The study indicates that the common ancestor of the coyote and gray wolf has genetically admixed with a ghost population of an extinct unidentified canid. The canid was genetically close to the dhole and had evolved after the divergence of the African wild dog from the other canid species. The basal position of the coyote compared to the wolf is proposed to be due to the coyote retaining more of the mitochondrial genome of this unknown canid.

This canid is genetically close to the dhole and evolved after the divergence of the African hunting dog from the other canid species. The basal position of the coyote compared to the wolf is proposed to be due to the coyote retaining more of the mitochondrial genome of this unidentified canid. Similarly, a museum specimen of a wolf from southern China collected in 1963 showed a genome that was 12–14% admixed from this unknown canid. In North America, most coyotes and wolves show varying degrees of past genetic admixture.

There is evidence of gene flow between golden jackals and Middle Eastern wolves, less so with European and Asian wolves, and least with North American wolves. The study proposes that the golden jackal ancestry found in North American wolves may have occurred before the divergence of the Eurasian and North American gray wolves. The study indicates that the common ancestor of the coyote and gray wolf has genetically admixed with a ghost population of an extinct unidentified canid. The canid is genetically close to the dhole and has evolved after the divergence of the African hunting dog from the other canid species.

The fossil remains of this canid are incomplete, hence they do not provide an accurate reconstruction. The species appears to have been diverged from Xenocyon, along with the African wild dog, Sardinian dhole and Mececyon trinilensis, another extinct Javanese canid. The Merriam's dog had a set of strong, robust teeth. Its size probably exceeded that of the extant African wild dog.

The Falkland Islands wolf (Dusicyon australis), also known as the warrah ( or ) and occasionally as the Falkland Islands dog, Falkland Islands fox, or Antarctic wolf, was the only native land mammal of the Falkland Islands. This endemic canid became extinct in 1876, the first known canid to have become extinct in historical times. Traditionally it had been supposed that the most closely related genus was Lycalopex, including the culpeo, which has been introduced to the Falkland Islands in modern times. However, in 2009, a cladistic analysis of DNA identified the Falkland Island wolf's closest living relative as the maned wolf (Chrysocyon brachyurus)—an unusually long-legged, fox-like South American canid, from which it separated about 6.7 million years ago.

Vulpes has a very similar bone structure to its canid relatives, but does have some modifications. Although canid limbs are designed specifically for running quickly on land to catch prey, Vulpes species avoid rapid sprints, excluding being chased, and have become more specialized for leaping and grasping prey. The adaptions for leaping, grasping, and climbing include the lengthening of hind limbs in relation to fore limbs, as well as overall slenderizing of both hind and fore limbs. Muscles are also emphasized along the axis of limbs.

A 2015 study reported genetic signatures in maned wolves that are indicative of population expansion followed by contraction that took place during Pleistocene interglaciations about 24,000 years before present. The maned wolf is not closely related to any other living canid. It is not a fox, wolf, coyote, dog, or jackal, but a distinct canid, though, based only on morphological similarities, it previously had been placed in the Canis and Vulpes genera. Its closest living relative is the bush dog (genus Speothos), and it has a more distant relationship to other South American canines (the short-eared dog, the crab-eating fox, and the zorros or Lycalopex).

It exists in southern China, which refutes claims made by some researchers in the Western world that the wolf had never existed in southern China. In 2019, a genomic study on the wolves of China included museum specimens of wolves from southern China that were collected between 1963-1988. The wolves in the study formed 3 clades: north Asian wolves that included those from northern China and eastern Russia, Himalayan wolves from the Tibetan Plateau, and a unique population from southern China. One specimen from Zhejiang province in eastern China shared gene flow with the wolves from southern China, however its genome was 12-14 percent admixed with a canid that may be the dhole or an unknown canid that predates the genetic divergence of the dhole.

Canis hybridisation in the distant past In 2018, whole genome sequencing was used to compare members of genus Canis, along with the dhole (Cuon alpinus) and the African hunting dog (Lycaon pictus). There is evidence of gene flow between African golden wolves, golden jackals, and gray wolves. The study suggests that the African golden wolf is a descendant of a genetically admixed canid of 72% grey wolf and 28% Ethiopian wolf ancestry, and that the Ethiopian wolf once had a wider range in Africa. One African golden wolf from the Egyptian Sinai Peninsula showed high admixture with the Middle Eastern gray wolves and dogs, highlighting the role of the land bridge between the African and Eurasian continents in canid evolution.

Genetic analysis has confirmed unique sequences of mtDNA, classifying the Japanese raccoon dog as a distinct isolation species, based on evidence of eight Robertsonian translocations. The International Union for Conservation of Nature Canid Group's Canid Biology and Conservation Conference in September 2001 rejected the classification of the Japanese raccoon dog as a separate species, but its status is still disputed, based on its elastic genome. The karyotype of Japanese raccoon dogs is different from that of the mainland raccoon dogs. Though it is unknown whether mainland raccoon dogs and Japanese raccoon dogs can produce fertile offspring, it is assumed that the chromosomal differences between them would have deleterious effects on the fertility of the potential offspring and this would be indicative of speciation.

The zorros are hunted in Argentina for their durable, soft pelts. They are also often labelled 'lamb-killers'. The Fuegian dog (), also known as the Yaghan dog, was a domesticated form of the culpeo (Lycalopex culpaeus), unlike other domesticated canids which were dogs and silver foxes. This means different canid species have been domesticated multiple times by humans independently.

Timeline of canids highlighting Canis lepophagus in red (Tedford & Wang) Canis lepophagus (Latin: : 'dog'; : 'hare' or 'rabbit'; suffix : '-eating'; hence hare-eating dog) is an extinct species of canid which was endemic to much of North America during the Early Pliocene. It is notable because its lineage is proposed to have led to both wolves and coyotes.

Lycaon is a genus of canid which includes the African wild dog (Lycaon pictus) and the extinct Lycaon sekowei. This hypercarnivorous and highly cursorial genus is distinguished by accessory cusps on the premolars. It branched from the wolflike canids lineage during the Plio-Pleistocene. Since then, Lycaon has become lighter and tetradactyl, but has remained hypercarnivorous.

Nyctereutes (Greek: nukt "night" + ereutēs "wanderer") is a genus of canid which includes only one extant species, the raccoon dog (Nyctereutes procyonoides). Nyctereutes first enters the fossil record 5.5 million years ago (Mya) in northern China. It was one of the earliest canines to arrive in the Old World. All but one species became extinct before the Pleistocene.

Phlaocyon was about in body length, and looked more like a cat or raccoon than a dog, but its skull anatomy shows it to be a primitive canid. Phlaocyon probably lived like a raccoon, often climbing trees. Its head was short, wide, and had forward-facing eyes. Unlike modern canides, Phlaocyon had no specialised teeth for slicing flesh.

Retrieved December 21, 2012. It is not recommended to use unleashed dogs to deter bear attacks. Although large, aggressive dogs can sometimes cause a bear to run, if pressed, angry bears often turn the tables and end up chasing the dogs in return. A bear in pursuit of a pet dog can threaten both canid and human lives.

The cercariae then leave the snail and infect the tadpole via penetration where a non-reproductive form is developed, which is known as mesocercariae. It usually takes about two weeks to develop. The mesocercariae transfer to their tissues and remain at this life-cycle stage. Finally, the parasite reaches its final host once ingested, usually a canid.

Although the maned wolf displays many fox-like characteristics, it is not closely related to foxes. It lacks the elliptical pupils found distinctively in foxes. The maned wolf's evolutionary relationship to the other members of the canid family makes it a unique animal. Electrophoretic studies did not link Chrysocyon with any of the other living canids studied.

The chief features which identify it as a canid include the loss of the upper third molar (part of a trend toward a more shearing bite), and the structure of the middle ear which has an enlarged bulla (the hollow bony structure protecting the delicate parts of the ear). Prohesperocyon probably had slightly longer limbs than its predecessors, and also had parallel and closely touching toes which differ markedly from the splayed arrangements of the digits in bears. The canid family soon subdivided into three subfamilies, each of which diverged during the Eocene: Hesperocyoninae (about 39.74–15 Mya), Borophaginae (about 34–2 Mya), and Caninae (about 34–0 Mya). The Caninae are the only surviving subfamily and all present-day canids, including wolves, foxes, coyotes, jackals, and domestic dogs.

Watercolor tracing made by archaeologist Henri Breuil from a cave painting of a wolf-like canid, Font-de- Gaume, France dated 19,000 years ago. In 2013, a leading evolutionary biologist stated: In 2015, a study looked at the mitogenome control region sequences of 13 ancient canid remains and one modern wolf from five sites across Arctic north-east Siberia. The 14 canids revealed nine haplotypes, three of which were on record and the others unique. Four of the Siberian canids dated 28,000 years before present (YBP), and one Canis variabilis dated 360,000 YBP. The phylogenetic relationship of the extracted sequences showed that the haplotype from specimen S805 (28,000 YBP) was one step away from another haplotype S902 (8,000 YBP) that represents the domestic dog and modern wolf lineages.

Metalopex is an extinct hypocarnivorous canid mammal similar to Vulpes endemic to Late Miocene North America. Its sister taxon is the extant Urocyon; together, the two genera form a clade based on dentition. These same dental characteristics are shared by Otocyon and Protocyon.Tedford, Richard H., Wang, Xiaoming, Taylor, Beryl E Phylogenetic systematics of the North American fossil Caninae (Carnivora, Canidae).

The species L. delicatus is the smallest canid to have existed. At the close of their genus 9 million years ago one Leptocyon lineage resembled the modern fox. Leptocyon were small-bodied, fox- like animals with a long, narrow jaw and delicate teeth. They were probably omnivorous, feeding on small animals and fruit in a diet that remained relatively unchanged during the Miocene.

If the person presenting symptoms lives in an area with poor sanitation, high wild dog population, or known endemic tapeworm, his chance of having coenurosis is much higher. Also, this disease is seen more often in children than adults because children spend time outside in the mud and generally are more likely than adults to come into contact with canid feces.

Cynodesmus once included numerous species of Oligocene and Miocene canid with highly carnivorous (hypercarnivorous) dentitions. A revision of the genus by Wang (1994) indicates that most species previously placed in Cynodesmus are unrelated to the type species, C. thooides. These other species have been placed the genera Carpocyon, Desmocyon, Leptocyon, Metatomarctus, Osbornodon, Otarocyon, Paracynarctus, Paratomarctus, and Phlaocyon (Wang, 1994; Wang et al., 1999).

The African golden wolf (Canis lupaster) is a canine native to North Africa and the Horn of Africa. It is the descendant of a genetically admixed canid of 72% gray wolf and 28% Ethiopian wolf ancestry. It occurs in Senegal, Nigeria, Chad, Morocco, Algeria, Tunisia, Libya , Kenya, Egypt, and Tanzania. It is listed as least concern on the IUCN Red List.

The following year, a major genetic study of Canis species also referred to the African golden wolf as Canis lupaster. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group recommended that because the specimen identified as Canis anthus Cuvier, 1820 was uncertain, the species should be known as Canis lupaster Hemprich and Ehrenberg, 1832 until Canis anthus can be validated.

The fennec fox is bred commercially as an exotic house pet. Commercial breeders remove the pups from their mother to hand-raise them, as tame foxes are more valuable. A breeders' registry has been set up in the United States to avoid any problems associated with inbreeding. The fennec fox is classified a "small wild/exotic canid" by the United States Department of Agriculture.

Based on a comparison with these early fossils, dingo morphology has not changed over thousands of years. This suggests that no artificial selection has been applied over this period and that the dingo represents an early form of dog. They have lived, bred, and undergone natural selection in the wild, isolated from other canines until the arrival of European settlers, resulting in a unique canid.

IUCN/SSC Canid Specialist Group. According to Enno Littmann, the people of Ethiopia's Tigray Region believed that injuring an African wild dog with a spear would result in the animal dipping its tail in its wounds and flicking the blood at its assailant, causing instant death. For this reason, Tigrean shepherds would repel African wild dog attacks with pebbles rather than with edged weapons.Littman, Enno (1910).

Archaeocyon was a comparatively small and unspecialized dog. Its dentition (teeth) suggests a slightly more hypocarnivorous (omnivorous) diet than the otherwise similar Hesperocyon. The skeleton is also generalized, lacking specializations for running and retaining a plantigrade foot posture. A few derived features of the dentition support a relationship to Borophaginae and Caninae (the subfamily that includes living canids), rather than to the basal canid subfamily Hesperocyoninae.

261-69 The species was first described scientifically in 1820 by Coenraad Temminck, after having examined a specimen taken from the coast of Mozambique. He named the animal Hyaena picta, erroneously classifying it as a species of hyena. It was later recognised as a canid by Joshua Brookes in 1827, and renamed Lycaon tricolor. The root word of Lycaon is the Greek λυκαίος (lykaios), meaning "wolf-like".

The species occurs throughout most rocky, wooded, brushy regions of the southern half of North America from southern Canada (Manitoba through southeastern Quebec) to the northern part of South America (Venezuela and Colombia), excluding the mountains of northwestern United States. It is the only canid whose natural range spans both North and South America. In some areas, high population densities exist near brush- covered bluffs.

The maned wolf (Chrysocyon brachyurus) is the largest canine of South America. Its markings resemble those of foxes, but it is neither a fox nor a wolf. It is the only species in the genus Chrysocyon (meaning "golden dog"). It is the largest canid in South America, with a weight between 20 and 30 kg, and reaches up to 90 cm at the withers.

Wolves typically dominate other canid species in areas where they both occur. In North America, incidents of wolves killing coyotes are common, particularly in winter, when coyotes feed on wolf kills. Wolves may attack coyote den sites, digging out and killing their pups, though rarely eating them. There are no records of coyotes killing wolves, though coyotes may chase wolves if they outnumber them.

10 of the 12 extant canid genera left-to-right, top-to-bottom: Canis, Cuon, Lycaon, Cerdocyon, Chrysocyon, Speothos, Vulpes, Nyctereutes, Otocyon, and Urocyon Canidae is a family of mammals in the order Carnivora, which includes domestic dogs, wolves, coyotes, foxes, jackals, dingoes, and many other extant and extinct dog-like mammals. A member of this family is called a canid; all extant species are a part of a single subfamily, Caninae, and are called canines. They are found on all continents except Antarctica, having arrived independently or accompanied human beings over extended periods of time. Canids vary in size, including tails, from the 2 meter (6 ft 7 in) gray wolf to the 46 cm (18 in) fennec fox. Population sizes range from the Falkland Islands wolf, extinct since 1876, to the wolf, whose domestic dog subspecies has a worldwide population of over 1 billion.

Omegaverse fiction typically focuses on wolf or other canid- like behavior in humans, especially as it pertains to sex. This includes rutting and heat cycles, pheromonal attraction between alphas and omegas, penises with knots ("knotting"), scent marking, breeding, and pack structures. Male omegas are also often conceived of as being able to become pregnant. The genre often features other fantasy elements, such as the presence of werewolves or other fantastical creatures.

Canis nehringi is an extinct species of canid. Canis gezi, a poorly known small wolf from the Ensenadan of South America, appears to have given rise to Canis nehringi, a Lujanian species from Argentina. Betra's analysis in 1988, places Canis dirus and Canis nehringi as sister taxa and as the most derived members of the genus Canis in the New World. The species was first described by Florentino Ameghino in 1902.

It is a high-frequency pulsed signal whose spectral appearance suggests a continuous source that is periodically interrupted, and might last as long as 800 milliseconds. Such a sound is not known for any other canid; however, a similar sound (with lower frequency) has been described for a dhole at the Moscow Zoo. When they are kept with dogs that bark, New Guinea singing dogs may mimic the other dogs.

Bones of wild animals dating back to the Mesolithic period (2550-2185 BCE) have been excavated from sites in Lānghnaj. These include a canid (probably wolf), mongoose, rhinoceros, wild boar, chital, hog deer, swamp deer, nilgai and blackbuck. The presence of wild cattle has also been suggested. The animals bones at Lānghnaj suggest that the area was covered by a combination of savannah and forest with interspersed wetlands.

The culpeo (Lycalopex culpaeus), sometimes known as the zorro culpeo, Andean zorro or Andean fox, is a South American fox species. It is the second-largest native canid on the continent, after the maned wolf. In appearance, it bears many similarities to the widely recognized red fox. It has grey and reddish fur, a white chin, reddish legs and a stripe on its back that may be barely visible.

The teeth of the bat-eared fox are much smaller and reduced in shearing surface formation than teeth of other canid species. This is an adaptation to its insectivorous diet. Due to its unusual teeth, the bat- eared fox was once considered as a distinct subfamily of canids (Otocyoninae). However, according to more recent examinations, it is more closely related to the true foxes of the genus Vulpes.

A 2016 genetic study of canid scats found that despite high coyote density inside the Red Wolf Experimental Population Area (RWEPA), hybridization occurs rarely (4% are hybrids). In late 2018, two canids that are largely coyote were found on Galveston Island, Texas with red wolf alleles (gene expressions) left from a ghost population of red wolves. Since these alleles are from a different population from the red wolves in the North Carolina captive breeding program, there has been a proposal to selectively cross-breed the Galveston Island coyotes into the captive red wolf population. Another study published around the same time analyzing canid scat and hair samples in southwestern Louisiana found genetic evidence of red wolf ancestry in about 55% of sampled canids, with one such individual having between 78–100% red wolf ancestry, suggesting the possibility of more red wolf genes in the wild that may not be present in the captive population.

During planning and environmental assessment of the effects of wolf restoration, biologists anticipated that coyotes would compete with the larger canid, perhaps resulting in disruption of packs and numerical declines. Coyotes occasionally lose their wariness of humans and frequent roadsides or developed areas, becoming conditioned to human food by receiving handouts or picking up food scraps. They can quickly learn bad habits like roadside begging behavior. This leads to potential danger for humans and coyotes.

Canis arnensis arrived in Mediterranean Europe 1.9 million years ago and is probably the ancestor of modern jackals. The paraphyletic nature of Canis with respect to Lycaon and Cuon has led to suggestions that the two African jackals should be assigned to different genera, Schaeffia for the side-striped jackal and Lupulella for the black-backed jackal or Lupulella for both.Viranta, S., Atickem, A., Werdelin, L., & Stenseth, N.

Some authors have proposed the reclassification of this lineage as a separate species. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau. The group recommends that this wolf lineage be known as the "Himalayan wolf" and classified as Canis lupus chanco until a genetic analysis of the holotypes is available. The Himalayan wolf lacks a proper morphological analysis.

C. senezensis (Martin 1973) is represented by two maxillary bone fragments. This medium-sized canid was discovered in Senez, France and dated 2.1-2.0 million years ago. In 2011, a study compared all of the 55 Early Pleistocene wolf-like specimens found across Europe and found that their morphometric variation was no different than that of modern wolf populations, with their difference in size representing male and female specimens. However, the study proposed two lineages.

The definitive hosts for these Taenia species are canids. The adult tapeworms live in the intestines of animals like dogs, foxes, and coyotes. Intermediate hosts such as rabbits, goats, sheep, horses, cattle and sometimes humans get the disease by inadvertently ingesting tapeworm eggs (gravid proglottids) that have been passed in the feces of an infected canid. This can happen from ingesting food, water or soil that has been contaminated by dog feces.

Some authors consider the extinct Canis subgenus named Xenocyon as ancestral to both the genus Lycaon and the genus Cuon. Subsequent studies on the canid genome revealed that the dhole and African wild dog are closely related to members of the genus Canis. This closeness to Canis may have been confirmed in a menagerie in Madras, where according to zoologist Reginald Pocock there is a record of a dhole interbred with a golden jackal.

It is commonly known as the Tasmanian tiger because of its striped lower back, or the Tasmanian wolf because of its canid-like characteristics. Various Aboriginal Tasmanian names have been recorded, such as "coorinna", "loarinna", "laoonana" and "lagunta", while "kaparunina" is used in the constructed language of Palawa kani. The species was native to Tasmania, New Guinea, and the Australian mainland.

Typical of most canid species, Cape foxes mate for life. They are capable of breeding all year long, unlike the red fox, although they typically have offspring in the months from October to January. The female Cape fox has a gestation period of 51 to 53 days and gives birth to a litter of one to six cubs (or kits). Reared underground in burrows, the cubs stay close to the den until they are about four months old.

Blakeney Eye has a long history of occupation, with many finds from the Neolithic, but few from Roman or Anglo-Saxon dates,Birks (2003) pp. 10–12. although a gold bracteate was a rare and significant 6th-century find.Birks (2003) p. 21. Animal and plant finds showed that both domesticated species, such as goats, and locally available prey such as curlews were eaten; rabbit and canid remains may reflect the use of fur from these mammals.

The description of a new species and genus was published in 1997, emerging from examination undertaken by Jeanette Muirhead on specimens obtained at the Riversleigh World Heritage Area. The genus combines the Wanyi ngamala, "died out", and the Ancient Greek kynos, alluding to a "dog" for the resemblance to the canid family. The specific epithet names Tim Mulvaney, who was gifted the honour by his aunt, Margaret Beavis, for long time support toward research of Riversleigh fauna.

The hottest month is May recording temperatures up to , while the coldest month is December to February when it reaches freezing temperature. The region received around of rainfall and the soil is conducive for agriculture. There are a number of flora and fauna species in the high plateau regions in the West. Notably this was historic habitat for the endangered painted hunting dog (Lycaon pictus), a canid which is now thought to be extirpated from the region.

Dogs reach sexual maturity and can reproduce during their first year in contrast to a wolf at two years. The female dog can bear another litter within 8 months of the last one. The canid genus is influenced by the photoperiod and generally reproduces in the springtime. Domestic dogs are not reliant on seasonality for reproduction in contrast to the wolf, coyote, Australian dingo and African basenji that may have only one, seasonal, estrus each year.

This was the same time as the appearance of the Borophaginae with whom they share features with, indicating that these were two sister groups. Borophaginae skull and dentition were designed for a powerful killing bite compared with the Leptocyon which were designed for snatching small, fast-moving prey. The species L. delicatus is the smallest canid to have existed. At the close of their genus 9 million years ago one Leptocyon lineage resembled the modern fox.

This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005). At one time this canid was proposed by some authors as a subspecies of the red wolf - the red wolf once lived primarily in Texas - "BREVARD COUNTY, FLORIDA: A Short History to 1955" – Google Docs. Docs.google.com. Retrieved on 2012-12-30.and that a variation in the red wolf's coloring led to the creation of the Florida black wolf.

Also, unlike other hyenas, the female spotted hyena's external genitalia closely resembles that of the male. Their dentition is similar to that of the canid, but is more specialised for consuming coarse food and crushing bones. The carnassials, especially the upper, are very powerful and are shifted far back to the point of exertion of peak pressure on the jaws. The other teeth, save for the underdeveloped upper molars, are powerful, with broad bases and cutting edges.

Hare obtained his Bachelor of Arts degree in Anthropology and Psychology from Emory University in 1998. As an undergraduate, he conducted research with Michael Tomasello, where he found that chimpanzees are sensitive to what other chimpanzees can and cannot see, and that domestic dogs can follow humans’ pointing gestures to find food. Hare continued his study of primate and canid cognition at Harvard University, where he was advised by Richard Wrangham. In 2004, he obtained his Ph.D in Biological Anthropology.

The gray wolf is the largest wild member of the canid family, with males averaging , and females . It is the most specialized member of its genus in the direction of carnivory and hunting large game. Although they primarily target ungulates, wolves are at times versatile in their diet; for example, those in the Mediterranean region largely subsist on garbage and domestic animals. They have powerful jaws and teeth and powerful bodies capable of great endurance, and often run in large packs.

The African golden wolf was found to be the descendant of a genetically admixed canid of 72% grey wolf and 28% Ethiopian wolf ancestry. The Ethiopian wolf does not share the single-nucleotide polymorphisms that confer hypoxia adaptation with the Himalayan wolf. The adaptation of the Ethiopian wolf to living in high elevations may occur at other single-nucleotide polymorphism locations. This indicates that the Ethiopian wolf's adaptation has not been inherited by descent from a common ancestor shared with the Himalayan wolf.

For example, the area was earlier a habitat for the African wild dog, Lycaon pictus, although this canid is likely extirpated at present in the local area, due to an expanding human population. Also deer, horses, lions, cheetah, tigers, and many others currently almost non-existed due to increasing population residence were once up on a time inhabited the town and its surrounding serial of rocky mountains called in the local language "Weeranayaasha" meaning "The surrounded ones" due to their shape.

The crab-eating fox (Cerdocyon thous), also known as the forest fox, wood fox, bushdog or maikong, is an extant species of medium-sized canid endemic to the central part of South America, and which appeared during the Pliocene epoch. Like South American foxes, which are in the genus Lycalopex, it is not closely related to true foxes. Cerdocyon comes from the Greek words kerdo (meaning fox) and kyon (dog) referring to the dog- and fox-like characteristics of this animal.

The crab-eating fox is a canid that ranges in savannas; woodlands; subtropical forests; prickly, shrubby thickets; and tropical savannas such as the caatinga, plains, and campo, from Colombia and southern Venezuela in the north to Paraguay, Uruguay and northern Argentina at the southernmost reaches of its range.J.F. Eisenberg, K.H. Redford Mammals of the Neotropics – The Central Neotropics, vol. 3, University of Chicago Press, Chicago (1999) The crab-eating fox has also been sighted in Panama since the 1990s.Tejera-N, VH; Araúz-G.

Almost one third of the 47 mammals that live in BMNP are rodents. The rodent community, particularly of the Afro-alpine plateau are keystone species in the Bale Mountains National Park. They are the main prey for Ethiopian wolf, and natural grazers of the Afro-alpine areas where important cryoturbation processes happen. The Afro-alpine area is home to over half of the global population of the Ethiopian wolf, the rarest canid in the world with only 400 animals surviving.

A 10-year national action plan was formed in February 2011. The species' critical situation was first publicised by the Wildlife Conservation Society in 1983, with the Bale Mountains Research Project being established shortly after. This was followed by a detailed, four-year field study, which prompted the IUCN/SSC Canid Specialist Group to produce an action plan in 1997. The plan called for the education of people in wolf-inhabited areas, wolf population monitoring, and the stemming of rabies in dog populations.

Vulpes lagopus is a 'true fox' belonging to the genus Vulpes of the fox tribe Vulpini, which consists of 12 extant species. It is classified under the subfamily Caninae of the canid family Canidae. Although it has previously been assigned to its own monotypic genus Alopex, recent genetic evidence now places it in the genus Vulpes along with the majority of other foxes. It was originally described by Carl Linnaeus in the 10th edition of Systema Naturae in 1758 as Canis lagopus.

Marking behavior is present in both male and female dogs, and is especially pronounced in male dogs that have not been neutered. Raised-leg urination is the most significant form of scent marking in wolves, and is most frequent around the breeding season. Wolves urine-mark more frequently when they detect the scent of other wolves, or other canid species. Leg-lifting is more common in male wolves than female wolves, although dominant females also use the raised-leg posture.
|
|
In 2002, orphometric analyses of skulls also indicate that the red wolf is likely not to be a gray wolf–coyote hybrid (Nowak 2002). Therefore, while the red wolf's taxonomic status remains unclear, there is mounting evidence to support C. rufus as a unique canid taxon. Classifying animals commonly referred to as "eastern coyotes" or "northeastern coyotes" has become a problem for taxonomists, as it is unclear what new taxon will be used to refer to this new population of animals.

In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature. Canis is the Latin word meaning "dog", and under this genus he listed the doglike carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as Canis familiaris, and the wolf as Canis lupus. Linnaeus considered the dog to be a separate species from the wolf because of its cauda recurvata—its upturning tail—which is not found in any other canid.

The park can be accessed via the N19 highway via Diapaga (in the dry season also via Pama). Arli National Park has several pools, such as Tounga where there is a waterhole and there are two pools which are often visited by up to twenty hippos. The park was earlier a habitat for the West African wild dog (Lycaon pictus manguensis), although this canid is likely extirpated from the local area due to an expanding human population, and a lack of national protection.

The family Thylacosmilidae was originally erected by Riggs in 1933, to accommodate Thylacosmilus, found in the Pliocene Brochero Formation of Argentina. Later, the family was demoted to a subfamily, as Thylacosmilinae, within Borhyaenidae, a group of superficially canid-like sparassodonts, under the assumption that Thylacosmilus was merely a late and specialized borhyaenid. Later, with the discovery of fragmentary specimens of new sparassodonts related to Thylacosmilus from Miocene and Pliocene strata, Thylacosmilidae was promoted back to familial status.Analía M. Forasiepi & Alfredo A. Carlini (2010).

Lloma de Betxí indoor interpretation The presence of human remains scattered among the remains of fauna is found. The handling of human remains is a fact in other contexts of the Bronze Age. This has been interpreted as the existence of a new funeral ritual. In addition, also they appeared two human burials: a senile individual along the skeleton of a small canid, and other structure bounded by a circular stone in a fetal position with legs bent and arms.

The fame he gained in his television career allowed him to become an advocate for the protection of endangered species, and through Wild Kingdom he gave many Americans their first exposure to the conservation movement. Perkins also helped establish the Wild Canid Survival and Research Center (WCSRC) near St. Louis in 1971. This wolf sanctuary has been instrumental in breeding wolves for eventual re- placement into their natural habitats. Perkins retired from active zookeeping in 1970 and from Wild Kingdom in 1985 for health reasons.

The description of a new species and genus was published in 2000, the results of examination of fossil material discovered at the "Blast Site", associated with the Bullock Creek fossil beds in the Northern Territory. The describing authors, Peter F. Murray and Dirk Megirian, assigned the name Mutpuracinus to the new thylacinid genus, combining the Ancient Greek kynos, alluding to the canid family of dogs and wolves, and the word mutpura in reference to an Indigenous Australian people associated with the district at Camfield.

Canis ferox (Latin: canis: dog, ferox: fierce; hence fierce dog) is a species of canid which was endemic to North America and lived during the Late Miocene and Early Pliocene,PaleoBiology Database: Canis ferox existing for approximately . The first fossil was found in Rancho Viejo, Guanajuato (Mexico). Researchers estimated that their weight could be between 13.3 kg and 14.3 kg, based on the Legendre and Roth correlations. Paleontologists Miller and Carranza-Castaneda noted that their skull resembled that of an ancestral coyote, Canis lepophagus.

Canis cedazoensis is an extinct species of smaller canid which was endemic to North America during the Pleistocene epoch, 1.8 Ma—300,000 years ago.PaleoBiology Database: Canis cedazoensis Timeline highlighting Canis cedazoensis in red The morphology and dentition of C. cedazoensis suggests a jackal-like animal that was more hypercarnivorous than any current jackal. C. cedazoensis is close in size to the living golden jackal. It' appears to form an endemic clade with Canis thooides and Canis feneus, and is possibly descended from Canis lepophagus.

The extinction of T. walleri and other phorusrhacids throughout the Americas may have resulted from competition with large placental (canid, felid, and possibly ursid) carnivores that radiated in the same ancient terrestrial ecosystems during the Great American Interchange. From circumstantial evidence (i.e., bone fractures), it has been suggested that the species did not become extinct until 15,000 years ago, but more precise dating by McFadden and colleagues refutes such a late date; all known Titanis fossils appear to be at least 2 million years old.

The Guassa area harbors nine (23%) of the endemic mammals of Ethiopia, including the Ethiopian wolf, the Gelada and the Ethiopian Highland hare. The Ethiopian wolf is legally protected and with a total world population of less than 450 is the most endangered canid in the world. With six packs of wolves, the Guassa area is a key population of the species. The gelada is the only living member of the once widespread genus Theropithecus and is only found in the highlands of northern Ethiopia.

Belgium 26,000 YBP has been found to be uniquely large but was found not to be related to the Beringian wolf. This Belgium canid clade may represent a phenotypically distinct and not previously recognized population of gray wolf, or the Goyet dog may represent an aborted domestication episode. If so, there may have been originally more than one ancient domestication event for dogs as there was for domestic pigs. A 2016 review proposed that it most likely represents an extinct morphologically and genetically divergent wolf population.

Polychrome tracing made by the archaeologist Henri Breuil from the cave painting of a wolf-like canid discovered in the Font-de-Gaume cave, Dordogne, France dated to 17,000 years ago. The Paleolithic dog was a Late Pleistocene canine. They were directly associated with human hunting camps in Europe over 30,000 years ago and it is proposed that these were domesticated. They are further proposed to be either a proto-dog and the ancestor of the domestic dog or an extinct, morphologically and genetically divergent wolf population.

Knowledge of the Denisovan humans derives primarily from DNA evidence and artifacts, as no complete skeletons have yet been recovered. DNA evidence has been unusually well preserved because of the low average temperature in the Denisova caves. Neanderthal bones and tools made by Homo sapiens have also been found in the Denisova Cave, making it the only place in the world where all three hominids are known to have lived. A dog-like canid from 33,000 years ago was found in the Razboinichya Cave.

From this name it can be ascertained that the virus' primary natural host is a canid (i.e. a member of the family Canidae; dogs etc.), that it is a member of the family Herpesviridae and subfamily Alphaherpesvirinae, and that it is the first herpesvirus named for which canids serve as primary natural hosts. A number of virus names (e.g. Epstein–Barr virus, also known as Human gammaherpesvirus 4) are so widely used that it may be impractical to attempt to insist on their replacement.

The Ethiopian wolf (Canis simensis), also known as the Simien jackal or Simien fox, is a canid native to the Ethiopian Highlands. It is similar to the coyote in size and build, and is distinguished by its long and narrow skull, and its red and white fur. Unlike most large canids, which are widespread, generalist feeders, the Ethiopian wolf is a highly specialised feeder of Afroalpine rodents with very specific habitat requirements. It is one of the world's rarest canids, and Africa's most endangered carnivore.

Since 2007, Norton has also been a regular host of The British Academy Television Awards. On 7 July 2007, Norton presented at Live Earth and undertook a trip to Ethiopia with the Born Free Foundation to highlight the plight of the Ethiopian wolf – the rarest canid in the world. In the same year, he was the subject of an episode of the BBC1 genealogy documentary Who Do You Think You Are?. Norton's chat show, The Graham Norton Show, began on 22 February 2007 on BBC Two.

Although the genome of a CTVT is derived from a canid (probably a dog, wolf or coyote), it is now essentially living as a unicellular, asexually reproducing (but sexually transmitted) pathogen. Sequence analysis of the genome suggests it diverged from canids over 6,000 years ago; possibly much earlier. The most recent estimates of its time of origin date it to about 11,000 years ago. However, the most recent common ancestor of extant tumors is more recent: it probably originated 200 to 2,500 years ago.

In North America, in places such as Coffee Ranch in Texas, Epicyon shared territory with the bear Agriotherium as well as the feliform Barbourofelis, machairodont cat Amphimachairodus coloradensis and fellow canid Borophagus. All of these animals were potential competitors that would have occasionally conflicted with Epicyon for food and territory. Prey for Epicyon included herbivores like the camel Aepycamelus, the pronghorn antelope Cosoryx, horses like Neohipparion and Nannippus, the peccary Prosthennops and rhinoceroses like Teleoceras, all of which could provide a suitable meal through hunting or scavenging.

Graywolf Press was founded by Scott Walker and Kathleen Foster in 1974, in a space provided by Copper Canyon Press in Port Townsend, Washington. The press was named for the nearby Graywolf Ridge and Graywolf River, and for the canid. The press had early successes publishing poetry heavyweights like Denis Johnson and Tess Gallagher. In 1984, Graywolf Press was incorporated as a 501(c)3 non-profit organization, and moved to St. Paul, Minnesota in 1985 with the support of the National Endowment for the Arts.

Unlike most large canid species (such as the gray wolf, the African hunting dog, or the dhole), the maned wolf is a solitary animal and does not form packs. It typically hunts alone, usually between sundown and midnight, rotating its large ears to listen for prey animals in the grass. They tap the ground with a front foot to flush out the prey and pounce to catch it. They kill prey by biting on the neck or back, and shaking the prey violently if necessary.

Darwin's fox or Darwin's zorro (Lycalopex fulvipes) is an endangered canid from the genus Lycalopex. It is also known as the zorro chilote or zorro de Darwin in Spanish and lives on Nahuelbuta National Park (Araucanía Region), the Valdivian Coastal Range (Los Ríos Region) in mainland Chile and Chiloé Island.Farías, A.A., M.A. Sepúlveda, E.A.

One African golden wolf from the Egyptian Sinai Peninsula shows admixture with Middle Eastern wolves and dogs. There is evidence of gene flow between golden jackals and Middle Eastern wolves, less so with European and Asian wolves, and least with North American wolves. This indicates the golden jackal ancestry found in North American wolves may have occurred before the divergence of the Eurasian and North American wolves. The common ancestor of the coyote and the wolf has admixed with a ghost population of an extinct unidentified canid.

The cladogram below is based on the DNA phylogeny of Lindblad-Toh et al. (2005), modified to incorporate recent findings on Canis species, In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group recommends that because DNA evidence shows the side-striped jackal (Canis adustus) and black-backed jackal (Canis mesomelas) to form a monophyletic lineage that sits outside of the Canis/Cuon/Lycaon clade, that they should be placed in a distinct genus, Lupulella Hilzheimer, 1906 with the names Lupulella adusta and Lupulella mesomelas.

Some suggest that Parictis may have emigrated from Asia into North America during the major sea level low about 37 mya, because of the continued evolution of the Amphicynodontinae into the Hemicyoninae in Asia.Several students (Erdbrink 1953, Kurten 1966, Mitchell and Tedford 1973, Thenius 1979) suggested that the evolutionary line between the canid subfamily Amphicynodontinae and the ursid subfamily Hemicyoninae was through the genera Cephalogale and Ursavus. Although no Parictis fossils have been found in East Asia, Parictis does appear in Eurasia and Africa, but not until the Miocene.

In 2018, whole genome sequencing was used to compare members of the genus Canis. The study supports the African golden wolf being distinct from the golden jackal, and with the Ethiopian wolf being genetically basal to both. There is evidence of gene flow between African golden wolves, golden jackals, and gray wolves. One African golden wolf from the Egyptian Sinai Peninsula showed high admixture with the Middle Eastern gray wolves and dogs, highlighting the role of the land bridge between the African and Eurasian continents in canid evolution.

Snow camouflage is the use of a coloration or pattern for effective camouflage in winter, often combined with a different summer camouflage. Summer patterns are typically disruptively patterned combinations of shades of browns and greys, up to black, while winter patterns are dominated by white to match snowy landscapes. Among animals, variable snow camouflage is a type of seasonal polyphenism with a distinct winter plumage or pelage. It is found in birds such as the rock ptarmigan, lagomorphs such as the Arctic hare, mustelids such as the stoat, and one canid, the Arctic fox.

There are predators such as spotted hyena, striped hyena and African leopard. The endangered painted hunting dog had populations in the Horn of Africa, but pressures from human exploitation of habitat along with warfare have reduced or extirpated this canid in this region. Some important bird species of the Horn are the black boubou, the golden-winged grosbeak, the Warsangli linnet, and the Djibouti spurfowl. The Horn of Africa holds more endemic reptiles than any other region in Africa, with over 285 species total and about 90 species which are found exclusively in the region.

Polymorphic populations of asexual or sexual yeast, and multicellular eukaryotes like Drosophila, can adapt to new environments through allele frequency change in standing genetic variation. Organisms with longer generations times, although costly, can be used in experimental evolution. Laboratory studies with foxesEarly Canid Domestication: The Fox Farm Experiment, p.2, by Lyudmila N. Trut, Ph.D., Retrieved February 19, 2011 and with rodents (see below) have shown that notable adaptations can occur within as few as 10–20 generations and experiments with wild guppies have observed adaptations within comparable numbers of generations.

Old Dingo the New Guinea Singing Dog. In the past, the New Guinea singing dog was considered "unworthy" of scientific study, as it was regarded as an insignificant variety of feral domestic dog. However, due to its potential value as a resource for the determination of the process of canid evolution and domestication, particularly in relation to the dingo, as well as several of its unique genetic, behavioral, ecological, reproductive and morphological characteristics, limited research has been undertaken. The New Guinea Department of Environment and Conservation has announced protection measures.

Tomarctus is a canid genus of the extinct subfamily Borophaginae which inhabited most of North America during the late Early Miocene to the Early Barstovian age of the Middle Miocene (23—16 million years ago). Tomarctus existed for approximately . This animal shared a period and ecology with a variety of bear dogs, giant mustelid genera, and the genus of bone-crushing canidae, Cynarctoides. As the bear dogs and giant mustelids became extinct, Tomarctus further radiated to fill a line of dogs which filled the hyena-like fruit eating and bone-crushing niches.

Depending on the species of bear, there is generally a preference for one class of food, as plants and animals are digested differently. Wolf subspecies (including wolves, dogs, dingoes, and coyotes) eat some plant matter, but they have a general preference and are evolutionarily geared towards meat. Also, the maned wolf is a canid whose diet is naturally 50% plant matter. While most mammals may display "omnivorous" behavior patterns depending on conditions of supply, culture, season and so on, they will generally prefer a particular class of food, to which their digestive processes are adapted.

Upset, Owen repairs Hubble's communicator and sends him a message declaring how much he loves him. The Greater Dane hears the message and is left curious by it so she approaches Hubble for his opinion on why the dogs on Earth are subservient to humanity when they should be ruling it. Hubble believes that the dogs and humans have formed a bond of love and loyalty. When asked where his own loyalty lies, Hubble asks the Greater Dane to refer to him as Hubble rather than Canid 3942, showing his bond with Owen.

The elephant exhibit was then turned into an exhibit for black rhinoceroses. The new $3.7 million Adventure Center (visitor services, administration, and education, all privately funded) and the new Creepy Crawler Center were also opened in 2007. In 2008, the zoo saw the opening of the maned wolf exhibit, which was initially home to a mother and son acquired from the Wild Canid Survival and Research Center in Eureka, Missouri. In June 2009, the zoo received an 8 year old white Bengal tiger named Havar from Busch Gardens Tampa Bay in Florida.

These oncospheres circulate in the blood until they lodge in suitable organs (skeletal muscle, eyes, brain, muscles or subcutaneous tissue). After about three months or so, the oncospheres develop into cystic like larvae balls called coenuri. The cycle perpetuates when a canid (definitive host) ingests the tissue of an infected intermediate host. When this happens, the maturing larvae reside in the small intestine of the definitive host until they mature into adult worms and begin producing eggs (which will eventually be passed through feces into the environment once again).

Hemicyon, also known as the "dog-bear" (literally "half dog", from Greek (half) + (dog)), is an extinct genus of hemicyonine bear, which probably originated in Eurasia but was found in Europe, Asia and North America during the Miocene epoch (), existing for approximately .Hemicyon at fossilworks Hemicyon is the best-known genus in the Hemicyoninae, a subfamily intermediate between bears and their canid ancestors but most often classified as bears. Hemicyonid bears evolved from dogs and should not be confused with Amphicyonids (bear-dogs), which are their own separate family of carnivores.

Coywolf (sometimes called woyote) is an informal term for a canid hybrid descended from coyotes, eastern wolves and gray wolves. All members of the genus Canis are genetically closely related with 78 chromosomes, therefore they can interbreed. One genetic study indicates that these two species genetically diverged relatively recently (around 55,000–117,000 years ago). Genomic studies indicate that nearly all North American gray wolf populations possess some degree of admixture with coyotes following a geographic cline, with the lowest levels occurring in Alaska, and the highest in Ontario and Quebec, as well as Atlantic Canada.

Flora and fauna Edit Giant forest hogs in the Harenna Forest, Bale Mountains NP, Ethiopia The Harenna Forest is known for its native plants, mammals, amphibians and birds, including many endemic species. [2] One such endemic species is the tree Maytenus harenensis, which is also classified by the IUCN as vulnerable due to the threat of logging.[3] The Harenna Forest was once habitat to packs of the endangered painted hunting dog, Lycaon pictus. However, the presence of this canid is now in question here due to the population pressures of expanding human presence.

Domestic dogs tend to have a litter size of 10, wolves 3, and feral dogs 5–8. Feral pups have a very high mortality rate with only 5% surviving at the age of one year, and sometimes the pups are left unattended making them vulnerable to predators. Domestic dogs stand alone among all canids for a total lack of paternal care. Dogs differ from wolves and most other large canid species as they generally do not regurgitate food for their young, nor the young of other dogs in the same territory.

The raccoon dog (Nyctereutes procyonoides, from the Greek words nykt-, "night-" + ereutēs, "wanderer" + prokyōn, "before-dog" [but "raccoon" in New Latin] + -oidēs, "similar to"), also known as the mangut (its Evenki name), tanuki or neoguri, is a canid indigenous to East Asia. It is the only extant species in the genus Nyctereutes. Despite its name, its closest relatives are the true foxes, and not the American raccoons. Among the Canidae, the raccoon dog shares the habit of regularly climbing trees only with the North American gray fox, another basal species.

Summers admits to working for the Sirians, but kills himself before revealing the identity of the robot spy. When Norrich helps bury Summers, Starr accuses him of being the robot, and Bigman threatens to shoot him; whereupon Mutt, coming to defend Norrich, is revealed as the robot himself. With the exposure of Mutt, Starr discerns that the Sirian spy ring on Earth must be the people who supplied Summers with Mutt, and who may be giving canid robot spies to others on Earth, and sets out to prevent them.

The Valentine Formation is a geologic formation or member within the Ogallala unit the out crops in South Dakota, Nebraska, and Kansas. It preserves fossils dating to the Neogene period and is particularly noted for Canid fossils. At the beginning of the Ogallala deposits washing out from the rising Rocky Mountains into the central plains states, the members of the Pierre Shale and Niobrara Formation outcrop had been largely exposed in their present range. The Niobrara had been incised by the present river systems, but to only a fraction of the present depths.

In the mandible, M1 (molar tooth) is relatively larger than in any other canid species.Miyamoto F, Maki I (1983) On the repaired specimen of Japanese wolf (Canis lupus hodophilax Temminck) and its skull newly taken out. Bull Fac Ed Wakayama Univ Nat Sci 32: 9–16 (in Japanese with English abstract) An examination in 1991 found one specimen's condylobasal length (a measure of skull length) to be 205.2mm, and the Alveolar length of P4 (the fourth maxillary premolar or carnassial tooth) to be 20.0mm (left) and 21.0mm (right).Miyamoto, F.

An alternative hypothesis has been put forward suggesting that the dogs died in an epidemic. However, this is inconsistent with the demographics of the buried dogs, as an outbreak would be expected to affect all members of the affected population, whereas the Ashkelon population is heavily skewed towards puppies. The dogs were physically similar, with close anatomical similarities to the present-day Canaan Dog. Rather than being a single breed, they appear to represent examples of a naturally occurring canid population adapted to the hot and semi-arid conditions of the region.

This lack of large prey caused the Sardinian dhole to evolve into a small sized (perhaps ) canid. This view of Cynotherium as a predator specializing in small, fast prey is supported by an examination of the animal's anatomy. The evolution of short, powerful limbs, a low neck carriage and increased head and neck mobility suggests an animal well suited for stalking and then quickly pouncing on or running down small prey. PDF copy Despite its common name, Cynotherium sardous is not always listed as a relative of the modern dhole.

There was 40%:60% wolf to coyote ancestry in red wolves, 60%:40% in Eastern timber wolves, and 75%:25% in the Great Lakes wolves. There was 10% coyote ancestry in Mexican wolves and the Atlantic Coast wolves, 5% in Pacific Coast and Yellowstone wolves, and less than 3% in Canadian archipelago wolves. If a third canid had been involved in the admixture of the North American wolf-like canids then its genetic signature would have been found in coyotes and wolves, which it has not. In 2018, whole genome sequencing was used to compare members of genus Canis.

The Himalayan wolf is distinguished by its mitochondrial DNA, which is basal to all other wolves. The taxonomic name of this wolf is disputed, with the species Canis himalayensis being proposed based on two limited DNA studies. In 2017, a study of mitochondrial DNA, X-chromosome (maternal lineage) markers and Y-chromosome (male lineage) markers found that the Himalayan wolf was genetically basal to the holarctic grey wolf and has an association with the African golden wolf. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group noted that the Himalayan wolf's distribution included the Himalayan range and the Tibetan Plateau.

Comparison between the skulls of the basal black-backed jackal (left) and advanced grey wolf Skull of a black-backed jackal The black-backed jackal is a fox-like canid with a slender body, long legs, and large ears. It is similar to the closely related side- striped jackal and more distantly related to the golden jackal, though its skull and dentition are more robust and the incisors much sharper. It weighs , stands at the shoulder, and measures in body length. The base colour is reddish brown to tan, which is particularly pronounced on the flanks and legs.

A scaled picture of the mandible of Vulpes skinneri Three associated small canid specimens (an M2, a rib and a posterior mandibular fragment including the P4, M1, coronoid, condylar and angular processes) that were originally attributed to Vulpes cf. V. chama are reassigned to V. skinneri. In the paper describing the new specimens, the authors argue that “we compare these specimens to a broad sample of modern and fossil foxes and conclude that these specimens are distinct enough to be referred to a new species” of the early Pleistocene, identified based on fossil remains dated to about 2 million years ago.

The canid has been referred to in scientific publications as Canis latrans, Canis latrans var., and Canis latrans × Canis lycaon, and has been commonly referred to as the eastern coyote, northeastern coyote, and coywolf. It is also called the southern tweed wolf. Coyotes and wolves first hybridized in the Great Lakes region, followed by a hybrid coyote expansion that created the largest mammalian hybrid zone known. In 2014, a DNA study of northeastern coyotes showed them on average to be a hybrid of western coyote (62%), western wolf (14%), eastern wolf (13%), and domestic dog (11%) in their nuclear genome.

The archipelago had only one terrestrial mammal upon the arrival of Europeans, the Falkland Islands wolf (also known as warrah), found on both major islands. It was traditionally thought that Patagonian Indians once brought the warrah to the islands as a hunting dog. However, a 2009 DNA study by scientists at UCLA suggested that the warrah arrived on the islands long before humans migrated to the New World, possibly during one of the particularly intense cold intervals 340,000 years ago, 150,000 years ago or 25,000 years ago. Its nearest relative was the maned wolf, an extant South American canid.

The dogs observed did not show the typical canid play bow; however, Imke Voth found this behavior during examinations in the 1980s. Several behaviors unique to New Guinea singing dogs have been noted: ;Head toss: This behavior, shown by every observed dog, is a prompt for attention, food or a sign of frustration, expressed in varying degrees depending on the level of arousal. In the complete expression, the head is swept to one side, nose rotated through a 90° arc to midline, then rapidly returned to the starting position. The entire sequence takes one to two seconds.

Most of their systematic and phylogenetic relationships have not been resolved because of their similar morphology. Upper Valdarno is the name given to that part of the Arno Valley situated in the provinces of Florence and Arezzo, Italy. The region is bounded by the Pratomagno mountain range to the north and east and by the Chianti Mountains to the south and west. The Upper Valdarno Basin has provided the remains of three fossil canid species dated to the Late Villafranchian era of Europe 1.9-1.8 million years ago that arrived with a faunal turnover around that time.

Ferrucyon is an extinct genus of omnivorous mammal of the family Canidae, which inhabited North America during the Pliocene, Blancan in the NALMA classification, from about 4.9 to approximately 2.6 Ma.Paleobiology Database: Cerdocyon avius The type species, F. avius, was originally interpreted as a relative of the modern crab-eating fox, and described as a species belonging to the genus Cerdocyon. Ruiz-Ramoni et al. (2020) reinterpreted it as a vulpine canid related to North American species Metalopex macconnelli, and to the Eurasian genus Nyctereutes. This reinterpretation necessitated removal of "Cerdocyon" avius from the genus Cerdocyon, and Ruiz-Ramoni et al.

The Ethiopian wolf is one of the rarest and most endangered of all canid species. The numerous names given to this species reflect previous uncertainties about its taxonomic position. However, the Ethiopian wolf is now thought to be related to the wolves of the genus Canis, rather that sold for about US$175 each to taxidermists who then retail the stuffed lions for US$400. "For the time being our immediate solution is to send them to the taxidermists, but the final and best solution is to extend the zoo into a wider area," Muhedin said.

States, cities, and towns in Western nations commonly enact local ordinances to limit the number or kind of pets a person may keep personally or for business purposes. Prohibited pets may be specific to certain breeds (such as pit bulls or Rottweilers), they may apply to general categories of animals (such as livestock, exotic animals, wild animals, and canid or felid hybrids), or they may simply be based on the animal's size. Additional or different maintenance rules and regulations may also apply. Condominium associations and owners of rental properties also commonly limit or forbid tenants' keeping of pets.

Given the position of the S805 haplotype on the phylogenetic tree, it may potentially represent a direct link from the progenitor (including Canis c.f. variabilis) to the domestic dog and modern wolf lineages. The gray wolf is thought to be ancestral to the domestic dog, however its relationship to C. variabilis, and the genetic contribution of C. variabilis to the dog, is the subject of debate. The Zhokhov Island (8,700 YBP) and Aachim (1,700 YBP) canid haplotypes fell within the domestic dog clade, cluster with S805, and also share their haplotypes with – or are one mutation away from – the Tibetan wolf (C. l.

Dhole skull and molars illustrated by St. George Mivart (1890) Captive adult dhole In appearance, the dhole has been variously described as combining the physical characteristics of the gray wolf and the red fox, and as being "cat-like" on account of its long backbone and slender limbs. It has a wide and massive skull with a well-developed sagittal crest, and its masseter muscles are highly developed compared to other canid species, giving the face an almost hyena-like appearance. The rostrum is shorter than that of domestic dogs and most other canids. The species has six rather than seven lower molars.

Fossils of Protocyon have been found in the Ñuapua and Tarija Formations of Bolivia, the Vorohue Formation of Buenos Aires, Argentina, Santa Elena Peninsula of Ecuador, Sopas Formation of Uruguay, Mene de Inciarte Tar Seep of Venezuela and various sites in Brazil, among others the Jandaíra Formation.Protocyon at Fossilworks.org Canid fossil material from the Hoyo Negro pit in the Sac Actun cave system (Mexico), initially identified as remains of a coyote, was reinterpreted as remains of Protocyon troglodytes by Schubert et al. (2019), indicating that this taxon was also present in the southern part of North America.

Phlaocyon mariae is an extinct species of the genus Phlaocyon, belonging to the subfamily Borophaginae and tribe Phlaocyonini, a canid which inhabited central western North America from the Miocene living 20.6–16.3 Ma, and existed for approximately . Phlaocyon mariae was described and named by , the name honours S. Marie Skinner who assembled and documented specimens from Nebraska. The species is known from worn upper and lower teeth and skull fragments found at the Early Hemingfordian Aletomeryx Quarry Site, Runningwater Formation, Cherry County, Nebraska. P. mariae is the largest Phlaocyon with teeth that display a mixture of hypo- and hypercarnivorous characters.

The striped hyena is primarily a scavenger, though it will also attack and kill any animals it can overcome, and will supplement its diet with fruit. The spotted hyena, though it also scavenges occasionally, is an active pack hunter of medium to large sized ungulates, which it catches by wearing them down in long chases and dismembering them in a canid-like manner. The aardwolf is primarily an insectivore, specialised for feeding on termites of the genus Trinervitermes and Hodotermes, which it consumes by licking them up with its long, broad tongue. An aardwolf can eat 300,000 Trinervitermes on a single outing.

The design and art direction for Lucario was provided by Ken Sugimori, a friend of the creator of the Pokémon games, Satoshi Tajiri. The species made its first non cameo appearance in the animated film Pokémon: Lucario and the Mystery of Mew, released in Japan in 2005. In an interview, Pokémon Diamond and Pearl director Junichi Masuda noted Lucario's name as one of the most difficult to create, due to an effort to make it appealing to both Japanese and American audiences. Lucario is a canid-like Pokémon that is a bipedal digitigrade with finger-like digits on its forepaws.

The South American foxes (Lycalopex), commonly called raposa in Portuguese, or zorro in Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not true foxes, but are a unique canid genus related to wolves and jackals; some of them somewhat resemble foxes due to convergent evolution. The South American gray fox, Lycalopex griseus, is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt. The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene.

On the rare occasions a bobcat kills a deer, it eats its fill and then buries the carcass under snow or leaves, often returning to it several times to feed. The bobcat prey base overlaps with that of other midsized predators of a similar ecological niche. Research in Maine has shown little evidence of competitive relationships between the bobcat and coyote or red fox; separation distances and territory overlap appeared random among simultaneously monitored animals. However, other studies have found bobcat populations may decrease in areas with high coyote populations, with the more social inclination of the canid giving them a possible competitive advantage.

The Range Wide Conservation Program for Cheetah and African Wild Dogs (RWCP) began in 2007 as a joint initiative of the IUCN Cat and Canid Specialist Groups, the Wildlife Conservation Society and the Zoological Society of London. National conservation plans have been developed successfully for several African countries. In 2014, the CITES Standing Committee recognised the cheetah as a "species of priority" in their strategies in northeastern Africa to counter wildlife trafficking. In December 2016 the results of an extensive survey detailing the distribution and demography of cheetahs throughout the range were published; the researchers recommended listing the cheetah as Endangered on the IUCN Red List.

In addition to extant canids, a number of prehistoric species have been discovered and classified as a part of Canidae. Morphogenic and molecular phylogenic research has placed them within the extant subfamily Caninae as well as the extinct subfamilies Hesperocyoninae and Borophaginae. Within Caninae, prehistoric species have been placed into both extant genera and separate extinct genera. The generally accepted classification of extinct canid species is primarily based for Hesperocyoninae on work by Xiaoming Wang, curator of terrestrial mammals at the Natural History Museum of Los Angeles County, and on work by Wang and zoologists Richard H. Tedford and Beryl E. Taylor for Borophaginae and Caninae.

Canids communicate by scent signals and vocalizations. One canid, the domestic dog, entered into a partnership with humans at least 14,000 years ago and today remains one of the most widely kept domestic animals. The 13 genera and 37 species of Caninae are primarily split into two tribes: Canini, which includes 9 genera and 20 species, comprising the wolf-like Canina subtribe and the South American Cerdocyonina subtribe; and Vulpini, the fox-like canids, comprising 3 genera and 14 species. Not included in either tribe is the Urocyon genus, which includes 2 species, mainly comprising the gray fox and believed to be basal to the family.

The description of a new species and genus was published in 2000, the results of examination of fossil material discovered at the "Blast Site", associated with the Bullock Creek fossil beds in the Northern Territory. The describing authors, Peter F. Murray and Dirk Megirian, assigned the name Tyarrpecinus to the new thylacinid genus, combining the Ancient Greek kynos, alluding to the canid family of dogs and wolves, and tyarrpa from the Arrente language for "cracked", alluding to the condition of the holotype. The fossil material described by the authors was a left maxilla, and remains of some teeth, which had been severely fragmented while in its state of deposition.

Canis (Xenocyon) falconeri mandible Upper Valdarno is the name given to that part of the Arno valley situated in the provinces of Florence and Arezzo, Italy. The region is bounded by the Pratomagno mountain range to the north and east and by the Chianti mountains to the south and west. The Upper Valdarno Basin has provided the remains of three fossil canid species dated to the Late Villafranchian era of Europe 1.9-1.8 million years ago that arrived with a faunal turnover around that time (Early Pleistocene). It is here that the Swiss paleontologist Charles Immanuel Forsyth Major discovered Falconer's wolf (Canis falconeri) (Forsyth Major 1877).

The Elmendorf Beast was the name given to a coyote blamed for several attacks on livestock in Elmendorf, Texas. Various opinions have been offered as to the identity of the creature, including that it was a Mexican Hairless Dog whose appearance had been altered by sickness and/or congenital ailments, and that it was a wolf-coyote cross. Some local people have linked it to the legend of the Chupacabra, while others believe that it was the product of a lab experiment that escaped, or that it was a previously unknown form of canid that was forced into contact with humans after its natural habitat was destroyed.

Erect bulbus glandis (1) in a Labrador Retriever The bulbus glandis (also called a bulb or knot) is an erectile tissue structure on the penis of canid mammals. During mating, immediately before ejaculation the tissues swell up to lock (tie) the male's penis inside the female. The locking is completed by circular muscles just inside the female's vagina; this is called "the knot" tightening thus preventing the male from withdrawing. The circular muscles also contract intermittently, which has the effect of stimulating ejaculation of sperm, followed by prostatic fluid, as well as maintaining the swelling of the penis and therefore the tie, for some time.

Canis arnensis skull at the Museum of Paleontology in Florence, Italy C. arnensis was a medium- sized canid, with a close affinity to modern canids. It had a slightly smaller cranial length than both C. etruscus and the extant C. lupus. C. arnensis featured a lower and more pronounced forehead, with less-developed sagittal and nuchal crests and a bulkier braincase than C. etruscus; in addition, the nasal bones were found to be shorter, stopping short of the maxillofrontal suture. C. arnensis and C. etruscus have been compared, as they are morphologically similar and are believed to have spread to Western Europe together during the so-called "Canis Event".

Cope recognised that clades of Cenozoic mammals appeared to originate as small individuals, and that body mass increased through a clade's history. Discussing the case of canid evolution in North America, Blaire Van Valkenburgh of UCLA and coworkers state: In some cases, the increase in body size may represent a passive, rather than an active, trend. In other words, the maximum size increases, but the minimum size does not; this is usually a result of size varying pseudo-randomly rather than directed evolution. This does not fall into Cope's rule sensu stricto, but is considered by many workers to be an example of "Cope's rule sensu lato".

When discovered in the 19th century and during the following decades, Phlaocyon was thought to be ancestral to raccoons because of shared convergent adaptations toward hypocarnivorous dentitions, but was the first to discover the canid nature of the middle ear region in P. leucosteus and Phlaocyon in now believed to be part of very diverse clade of hypocarnivorous canids, the Phlaocyonini, and only distantly related to raccoons. P. mariae and P. yatkolai, both known from isolated teeth and fragmentary material, are the largest and most derived species, and both display a tendency away from the hypocarnivorous dentition of the genus and towards a more hypercarnivorous dentition.

The basal position of the coyote compared to the wolf is proposed to be due to the coyote retaining more of the mitochondrial genome of this unknown canid. A genomic study on the wolves of China included museum specimens of wolves from southern China that were collected between 1963 and 1988. The wolves in the study formed 3 clades: north Asian wolves that included those from northern China and eastern Russia, Himalayan wolves from the Tibetan Plateau, and a unique population from southern China. One specimen located as far southeast as Jiangxi province shows evidence of being admixed between Tibetan-related wolves and other wolves in China.

In 2015, a study looked at the mitochondrial control region sequences of 13 ancient canid remains and one modern wolf from five sites across Arctic north- east Siberia. The fourteen canids revealed nine mitochondrial haplotypes, three of which were on record and the others not reported before. The phylogentic tree generated from the sequences showed that four of the Siberian canids dated 28,000 YBP and one Canis c.f. variabilis dated 360,000 YBP were highly divergent. The haplotype designated as S805 (28,000 YBP) from the Yana River was one mutation away from another haplotype S902 (8,000 YBP) that represents Clade A of the modern wolf and domestic dog lineages.

The dhole (; Cuon alpinus) is a canid native to Central, South, East Asia, and Southeast Asia. Other English names for the species include Asian wild dog, Asiatic wild dog, Indian wild dog, whistling dog, red dog, and mountain wolf. It is genetically close to species within the genus Canis, but distinct in several anatomical aspects: its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars sport only a single cusp as opposed to between two and four. During the Pleistocene, the dhole ranged throughout Asia, Europe, and North America but became restricted to its historical range 12,000–18,000 years ago.

The eastern timber wolf (Algonquin Provincial Park) is genetically closely related to the Great Lakes wolf (Minnesota, Isle Royale National Park). If a third canid had been involved in the admixture of the North American wolf-like canids, then its genetic signature would have been found in coyotes and wolves, which it has not. Grey wolves suffered a species-wide population bottleneck (reduction) approximately 25,000 YBP during the Last Glacial Maximum. This was followed by a single population of modern wolves expanding out of a Beringia refuge to repopulate the wolf's former range, replacing the remaining Late Pleistocene wolf populations across Eurasia and North America as they did so.

The eastern wolf as found in Algonquin Provincial Park is genetically closely related to the Great Lakes wolf as found in Minnesota and Isle Royale National Park in Michigan. If a third canid had been involved in the admixture of the North American wolf-like canids, then its genetic signature would have been found in coyotes and wolves, which it has not. Later in 2018, a study based on a much smaller sample of 65,000 SNPs found that although the eastern wolf carries regional gray wolf and coyote alleles (gene variants), it also exhibits some alleles that are unique and therefore worthy of conservation.

Watercolor tracing made by archaeologist Henri Breuil from a cave painting of a wolf-like canid, Font-de-Gaume, France dated 19,000 years ago. In 2015, a study undertook an analysis of the complete mitogenome sequences of 555 modern and ancient dogs. The sequences showed an increase in the population size approximately 23,500 YBP, which broadly coincides with the proposed genetic divergence of the ancestors of dogs and present-day wolves before the Last Glacial Maximum. A ten-fold increase in the population size occurred after 15,000 YBP, which may be attributable to domestication events and is consistent with the demographic dependence of dogs on the human population.

She also blamed the Doctor for his inability to save a young woman named Cassie in Project: Lazarus (2003), something the Seventh Doctor said she never forgave him for, even when she parted ways with him. While visiting the planet Világ and helping repel an alien invasion by an aggressive humanoid canid species known as the Killorans, Evelyn met and fell in love with Governor Rossiter, who eventually became the political head of the union of three nations (Arrangements for War, 2004). When she and the Doctor returned a year later, Evelyn decided to stay and marry Rossiter. She subsequently became involved in the politics of Világ and underwent surgery for her heart.

The golden jackal (Canis aureus) is a wolf-like canid that is native to Southeast Europe, Southwest Asia, South Asia, and regions of Southeast Asia. Compared with the Arabian wolf, which is the smallest of the gray wolves (Canis lupus), the jackal is smaller and possesses shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle. The golden jackal's coat can vary in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is listed as 'least concern' on the IUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter.

Representatives of three canid subfamilies: Hesperocyon (Hesperocyoninae), Aelurodon (Borophaginae) and Canis aureus (Caninae) The Canidae today includes a diverse group of some 34 species ranging in size from the maned wolf with its long limbs to the short-legged bush dog. Modern canids inhabit forests, tundra, savannahs, and deserts throughout tropical and temperate parts of the world. The evolutionary relationships between the species have been studied in the past using morphological approaches, but more recently, molecular studies have enabled the investigation of phylogenetics relationships. In some species, genetic divergence has been suppressed by the high level of gene flow between different populations and where the species have hybridized, large hybrid zones exist.

Males rarely disperse, and when they do, they are invariably rejected by other packs already containing males. Although arguably the most social canid, the species lacks the elaborate facial expressions and body language found in the grey wolf, likely because of the African wild dog's less hierarchical social structure. Furthermore, while elaborate facial expressions are important for wolves in re-establishing bonds after long periods of separation from their family groups, they are not as necessary to African wild dogs, which remain together for much longer periods. African wild dog populations in East Africa appear to have no fixed breeding season, whereas those in Southern Africa usually breed during the April–July period.

|
During estrus, the female is closely accompanied by a single male, which keeps other members of the same sex at bay. The copulatory tie characteristic of mating in most canids has been reported to be absent or very brief (less than one minute) in African wild dog, possibly an adaptation to the prevalence of larger predators in its environment. The gestation period lasts 69–73 days, with the interval between each pregnancy being 12–14 months typically. The African wild dog produces more pups than any other canid, with litters containing around six to 16 pups, with an average of 10, thus indicating that a single female can produce enough young to form a new pack every year.

Red fox kits Order: Carnivora, Family: Canidae Occurrence: Grasslands, open forest The red fox (Vulpes vulpes) is a small canid native to much of North America and Eurasia, as well as northern Africa. It is the most recognizable species of fox and in many areas it is referred to simply as "the fox". As its name suggests, its fur is predominantly reddish brown, but there is a naturally occurring gray morph known as the "silver" fox. The red fox is by far the most widespread and abundant species of fox, found in almost every single habitat in the Northern Hemisphere, from the coastal marshes of United States, to the alpine tundras of the Tibetan Plateau.

Nowak and Tedford also believed that it was possible for C. lupus to have been derived from a Miocene or Pliocene canid line that preceded and was separate from C. lepophagus. Based on morphology from China, the Pliocene wolf C. chihliensis may have been the ancestor for both C. armbrusteri and C. lupus before their migration into North America. C. chihliensis appears to be more primitive and smaller than C. lupus, and measurements of its skull and teeth are similar to C. lupus but those of its postcranial elements are smaller. C. armbrusteri appeared in North America in the Middle Pleistocene and is a wolf-like form larger than any Canis at that time.

Indian Forester, 117(10), 915–920. In one case, a golden jackal (a species much smaller and less powerful than a sloth bear and not generally a pack hunter as is the dhole) was seen to aggressively displace an adult bear which passively loped away from the snapping canid, indicating the sloth bear does not regard other carnivores as competition. Sloth bears are sympatric with Asiatic black bears in northern India, and the two species, along with the sun bear, coexist in some of the national parks and wildlife sanctuaries. They are also found together in Assam, Manipur, and Mizoram, in the hills south of the Brahmaputra River, the only places occupied by all three bear species.

The closest approximation to human morality that can be found in nature is that of the grey wolf, Canis lupus. Wolves are among the most gregarious and cooperative of animals on the planet, and their ability to cooperate in well-coordinated drives to hunt prey, carry items too heavy for an individual, provisioning not only their own young but also the other pack members, babysitting etc. are rivaled only by that of human societies. Similar forms of cooperation are observed in two closely related canids, the African wild dog and the Asian dhole, therefore it is reasonable to assume that canid sociality and cooperation are old traits that in terms of evolution predate human sociality and cooperation.

Fossil remains of C. adustus date back to the Pliocene era. A mitochondrial DNA sequence alignment for the wolf- like canids gave a phylogenetic tree with the side-striped jackal and the black-backed jackal being the most basal members of this clade, which means that this tree is indicating an African origin for the clade. In 2019, a workshop hosted by the IUCN/SSC Canid Specialist Group recommends that because DNA evidence shows the side-striped jackal (Canis adustus) and black-backed jackal (Canis mesomelas) to form a monophyletic lineage that sits outside of the Canis/Cuon/Lycaon clade, that they should be placed in a distinct genus, Lupulella Hilzheimer, 1906 with the names Lupulella adusta and Lupulella mesomelas.

This was the first time they had cloned a dog that had been dead for such a long time. In 2016, Hwang's company was regularly cloning pigs which were genetically predisposed to certain diseases so that they could be used for testing pharmaceuticals and cloning cattle which were highly valued for their meat. In total Sooam Biotech was reported to be producing roughly 500 cloned embryos a day from various species. They were also reported to be attempting to clone the Ethiopian wolf, one of the world's rarest canids, of which there are only 500 in the wild, another endangered canid, the Dhole, of which there only about 2,500 adults and the Siberian musk deer which is classified as vulnerable by the IUCN.

Several skulls of fossil large canids from sites in Belgium, the Ukraine and Russia were examined using multivariate analysis to look for evidence of the presence of Paleolithic dogs that were separate from Pleistocene wolves. Reference groups included the Eliseevichi-1 prehistoric dogs, recent dogs and wolves. The osteometric analysis of the skulls indicated that the Paleolithic dogs fell outside the skull ranges of the Pleistocene wolf group and the modern wolf group, and were closer related to those of the Eliseevichi-1 prehistoric dog group. The fossil large canid from Goyet, Belgium dated at 36,000 YBP was clearly different from the recent wolves, resembling most closely the Eliseevichi-1 prehistoric dogs and suggesting that dog domestication had already started during the Aurignacian.

Phlaocyon minor is an extinct species of canid mammal known from the Miocene- Oligocene (Arikareean NALMA, more than ) of the United States (Wyoming, South Dakota, Nebraska, Wyoming, and Texas.) The type specimen of P. minor is a partial maxilla, a partial dentary, and limb fragments found in Oglala Lakota County, South Dakota (: paleocoordinates ). referred half a dozen other specimens to P. minor, including a nearly complete skull and a mandible from Wyoming. P. minor is the most basal member of Phlaocyon but it can still be distinguished from more primitive borophagines such as Archaeocyon, Rhizocyon, and Cynarctoides. Characters placing it in Phlaocyon includes robust and shortened premolars, a quadrate first upper molar, and widened talonid on the first lower molar.

Other threatened species include two riparian fauna: the threatened California red-legged frog (Rana draytonii) and the western pond turtle (Actinemys marmorata). Pair of gray foxes (Urocyon cinereoargenteus), the only tree-climbing canid in the Americas, den and forage for rodents, grasshoppers and berries near the mouth of Matadero Creek in the Palo Alto Baylands Recently, gray foxes (Urocyon cinereoargenteus) have been documented near the mouth of San Francisquito Creek (see photo) and on the Palo Alto Golf Course. Populations of gray fox have increased in the South Bay since the U.S. Fish and Wildlife Service has culled non-native red foxes (Vulpes vulpes) because the latter prey on the endangered California clapper rail (Rallus longirostris obsoletus). Genetically, gray fox are the most basal of all canids.

In 2020, a literature review of canid domestication stated that modern dogs were not descended from the same Canis lineage as modern wolves, and proposes that dogs may be descended from a Pleistocene wolf closer in size to a village dog. The genetic divergence between dogs and wolves occurred between 20,000 and 40,000 years ago, just before or during the Last Glacial Maximum (20,000-27,000 years ago). This period represents the upper time-limit for domestication commencement because it is the time of divergence and not the time of domestication, which occurred later. One of the most critical transitions in human history was the domestication of animals, which began with the long-term association between wolves and hunter–gatherers more than 15,000 years ago.

In one cryptozoological investigation on a corpse of what was initially labelled as a chupacabra, examinations conducted by the UC Davis team and the Texas State University concluded based on the sex chromosomes that the male animal was in fact another coyote and wolf hybrid sired by a male Mexican wolf. DNA analysis consistently shows that all existing red wolves carry coyote genes. This has caused a problem for canid taxonomy, as hybrids are not normally thought of as species, though the convention is to continue to refer to red wolves as a subspecies of the gray wolf, Canis lupus rufus, with no mention of the coyote taxon latrans. In recent history, the taxonomic status of the red wolf has been widely debated.

The appearance of this animal was vaguely similar to that of a particularly robust, large felid, but the skull resembles that of a canid or an ursid, like that of many amphicyonids. Unlike most other amphicyonids, Magericyon had teeth associated with those of a hypercarnivore, with laterally flattened canines, the third premolar having a single root, the absence of second premolars and a metaconid on its lower molars, with a reduction in the second upper molar. The scapula and the front leg showed primitive features such as an acromion in the shoulder with a reduced caudoventral projection and post scapular pit.Peigné, S., Salesa, M. J., Antón, M. & Morales, J., 2008: A new amphicyonine (Carnivora: Amphicyonidae) from the upper Miocene of Batallones-1, Madrid, Spain.

The first record of genus Canis on the African continent is Canis sp. A from South Turkwel, Kenya dated 3.58–3.2 million years ago. In 2015, a study of mitochondrial genome sequences and whole genome nuclear sequences of African and Eurasian canids indicated that extant wolf- like canids have colonised Africa from Eurasia at least 5 times throughout the Pliocene and Pleistocene, which is consistent with fossil evidence suggesting that much of African canid fauna diversity resulted from the immigration of Eurasian ancestors, likely coincident with Plio-Pleistocene climatic oscillations between arid and humid conditions. In 2017, the fossil remains of a new Canis species named Canis othmanii was discovered among remains found at Wadi Sarrat, Tunisia from deposits that date 700,000 years ago.

Later, this process occurred in the Great Lakes region and then eastern Canada with the influx of coyotes replacing wolves, followed by the expansion of coyotes and their hybrids. The Great Lakes and Algonquin wolves largely reflect lineages that have descendants in the modern wolf and coyote populations, but also reflect a distinct gray wolf ecotype which may have descendants in the modern wolf populations. The proposed timing of the wolf/coyote divergence conflicts with the finding of a coyote-like specimen in strata dated to 1 million years before present. In 2017 a group of canid researchers challenged the 2016 whole-genome DNA study's finding that the red wolf and the eastern wolf were the result of recent coyote–gray wolf hybridization.

An extinct Late Pleistocene wolf may have been the ancestor of the dog, with the dog's similarity to the extant grey wolf being the result of genetic admixture between the two. In 2020, a literature review of canid domestication stated that modern dogs were not descended from the same Canis lineage as modern wolves, and proposes that dogs may be descended from a Pleistocene wolf closer in size to a village dog. The genetic divergence between dogs and wolves occurred between 20,000–40,000 years ago, just before or during the Last Glacial Maximum (20,000–27,000 years ago). This timespan represents the upper time-limit for the commencement of domestication because it is the time of divergence but not the time of domestication, which occurred later.

The sha is usually depicted as a slender canid, resembling a greyhound or a jackal, with three distinguishing features: a stiff tail, often forked at the end, which stands straight up or at an angle, whether the animal is sitting, standing, or walking; its ears, also held erect, are usually depicted as squarish or triangular, narrowest at the base and widest at the squarish tops; and a long nose, often with a slight downward curve. It is normally depicted as black, but may also have been reddish.E. A. Wallis Budge, The Gods of the Egyptians: Studies in Egyptian Mythology (1904)New Larousse Encyclopedia of Mythology (1974) The Set animal is usually depicted at rest, either lying down or seated. The shape of the head often resembles a giraffe, causing confusion between the two signs.

The few positively identified wolf remains were thought to have been transported to the cave system by hyenas for consumption. William Buckland, in his Reliquiae Diluvianae, wrote that he only found one molar tooth which could be positively identified as being that of a wolf, while other bone fragments were indistinguishable from those of domestic dogs. In the Paviland limestone caves of the Gower Peninsula in south Wales, the jaw, a heel bone and several metatarsals were found of a large canid, though it was impossible to definitively prove that they belonged to a wolf rather than a large dog. In a series of caves discovered in a quarry in Oreston, Plymouth, a Mr. Whidbey found several bones and teeth of a species of canis indistinguishable from modern wolves.

Hubble, who is really named Canid 3942, has been sent by the powerful Greater Dane (voice of Vanessa Redgrave) on a mission from the Dog Star Sirius 7 to make sure dogs have fulfilled this destiny. The dogs Owen walks include pampered Poodle Barbara Ann (voiced by Delta Burke), rambunctious Boxer Wilson (voiced by Donald Faison), nervous Italian Greyhound Nelly (voiced by Brittany Murphy) and Connie's gassy Bernese Mountain Dog Shep (voiced by Carl Reiner). Despite the best efforts of Owen and this rag-tag group of neighborhood dogs to convince Hubble that everything is fine with Earth's dogs, Hubble soon discovers the awful truth about Earth dogs: "You're all pets!" Things get worse when Hubble learns that the Greater Dane is headed for Earth to do her own inspection.

In 2015, a study of mitochondrial genome sequences and whole genome nuclear sequences of African and Eurasian canids indicated that extant wolf-like canids have colonised Africa from Eurasia at least five times throughout the Pliocene and Pleistocene, which is consistent with fossil evidence suggesting that much of African canid fauna diversity resulted from the immigration of Eurasian ancestors, likely coincident with Plio-Pleistocene climatic oscillations between arid and humid conditions. According to a phylogeny derived from nuclear sequences, the Eurasian golden jackal (Canis aureus) diverged from the wolf/coyote lineage 1.9 million years ago, and with mitochondrial genome sequences indicating the Ethiopian wolf diverged from this lineage slightly prior to that. Further studies on RAD sequences found instances of Ethiopian wolves hybridizing with African golden wolves.Bahlk, S.H. (2015).

A study conducted in 1990 of black and gray morphs of the eastern gray squirrel concluded that there was no major difference in behavior between the morphs. The same study also found no difference between the morphs when reacting to either a human or canid predator. However, another study in 2010 also found that gray morphs of the eastern gray squirrel were more prone to initiate flight than black morphs after hearing a red-tailed hawk; although the fact that black morphs were less likely to initiate flight after hearing a red-tailed hawk may not be an effect of pigmentation, rather the environment they inhabit. Given the higher frequency of black morphs in urban setting, it has been suggested that black morphs have a higher tolerance for human/urban stimuli.

More recent researchers have revisited Pei's view that the ancestor of the dog is a now extinct Canis lupus, and proposed that C. variabilis might be an ancestor of the dog lineage. In 2012, a study of the wolf-like Canis species of ancient China conducted by the noted vertebrate paleontologist and geologist Xiaoming Wang found that C. variabilis was "very strange" compared to other Canis in China as it had much smaller cranio-dental dimensions than earlier and later species. The study concluded that "It is very likely that this species is the ancestor of the domestic dog Canis familiaris, a hypothesis that has been proposed by previous authors." In 2015, a study looked at the mitochondrial control region sequences of 13 ancient canid remains and one modern wolf from five sites across Arctic north-east Siberia.

The presence of the warrah, Dusicyon australis, has often been cited as evidence of pre- European occupation of the islands. However, in 2009, this hypothesis was disproved when DNA analysis identified the Falkland Island wolf's closest living relative as the maned wolf (Chrysocyon brachyurus) – an unusually long- legged, fox-like South American canid, from which it separated about 6.7 million years ago. It would seem that the lineages of the maned wolf and the Falkland Islands wolf separated in North America; canids did not appear in South America until roughly 3 million years ago in a paleozoogeographical event called the Great American Biotic Interchange, in which the continents of North and South America were newly connected by the formation of the Isthmus of Panama. This means it is likely that the warrah arrived in the islands long before humans.

Early morning in a Gash Barka village It is situated in the south-west of the country, bordering the Anseba region to the north, and the Maekel (Central) and Debub (Southern) regions to the east; the country of Sudan lies to the west and Ethiopia to the south. The major crops in the region are bananas, tomatoes, cotton, onions, millet, sesame, green pepper and sweet melon. Within the entire country there existed extensive forestation as recently as 1900 AD; however, there is less than one percent forested area present in the country, and this deforestation trend has been mirrored in the region. Most of Eritrea was previously habitat for the endangered painted hunting dog, Lycaon pictus; however, this canid is now deemed extirpated from Gash-Barka and all of Eritrea due to the expanding human population in this country.

The site accounts for a remarkable variety of prehistoric objects: thousands of bones of prehistoric humans and large mammals, a whistle, stone artifacts with stylized engravings, an approximately 5,000 year old child's grave, the fossilized cranium of a Paleolithic dog, a knife made from a human rib, the largest collection of Neanderthal fossils of Northern Europe, hand axes, harpoons, necklaces, ivory chopsticks, engraved ivory platelets, carved reindeer horn and skinned and filleted human remains, that suggest cannibalism among Neanderthals. Horizons 1 and 2, . Artifacts of the Magdalenian levels include hand axes and a harpoon, a necklace of 26 wolves perforated teeth, bone fragments and needles, a biserial (multiple barbs on both edges) bone harpoon, a necklace, a Turritella sea snail shell necklace. Horizon 4 included a fossilized canid skull, which has been direct AMS dated to be 31,000 years old.

In 2015, a study of mitochondrial genome sequences and whole-genome nuclear sequences of African and Eurasian canids indicated that extant wolf-like canids have colonized Africa from Eurasia at least five times throughout the Pliocene and Pleistocene, which is consistent with fossil evidence suggesting that much of African canid fauna diversity resulted from the immigration of Eurasian ancestors, likely coincident with Plio-Pleistocene climatic oscillations between arid and humid conditions. When comparing the African and Eurasian golden jackals, the study concluded that the African specimens represented a distinct monophyletic lineage that should be recognized as a separate species, Canis anthus (African golden wolf). According to a phylogeny derived from nuclear sequences, the Eurasian golden jackal (Canis aureus) diverged from the wolf/coyote lineage 1.9 Mya, but the African golden wolf separated 1.3 Mya. Mitochondrial genome sequences indicated the Ethiopian wolf diverged from the wolf/coyote lineage slightly prior to that.

Matadero Creek at Hillview Road, Palo Alto, with Great Blue Heron Three gray foxes (Urocyon cinereoargenteus), the only tree-climbing canid in the Americas, den and forage for rodents, grasshoppers, and berries near the mouth of Matadero Creek in the Baylands View of Interstate 280 from the Matadero Creek Trail, which crosses the hill between Matadero Creek and its Deer Creek tributary Recently, gray fox (Urocyon cinereoargenteus) have been documented near the mouth of Matadero Creek (see photo). Populations of gray fox have increased in the South Bay since the U.S. Fish and Wildlife Service has culled non-native red fox (Vulpes vulpes) because the latter prey on endangered California clapper rail (Rallus longirostris obsoletus). Genetically, gray fox are the most basal of all canids. Steelhead trout (Oncorhynchus mykiss) were supported by Matadero Creek historically, and at least as recently as the late 1980s.

Several studies of the skeleton, including a comparison with Hemicyon ursinus, a fossil bear widely accepted as a predator, show that Agriotherium did not have the limb strength or speed needed for active hunting, either by ambush or by chasing down prey. It also did not show the long claws and increased forelimb strength typical of mammals that dig for food. These very large bears may have specialized on a combination of grazing, eating fruit and invertebrate food in season, and intimidating predators away from carcasses in order to scavenge meat and bone marrow. Very large size would have been necessary to steal and defend kills in environments dominated by some of the most powerful carnivorous mammals that have ever lived, such as the sabertooth cat Amphimachairodus, with whom it shared territory in both Afro-Eurasia and North America, and the bone-cracking canid Epicyon and the massive feliform sabertooth Barbourofelis, which it lived alongside in Texas, as evidenced by fossil deposits at Coffee Ranch.

The tree illustrates the genotype-phenotype distinction, where a genotype is an organism's full hereditary information and a phenotype is an organism's actual observed properties, such as morphology, development, or behavior. By phenotype, the dhole (genus Cuon) and the African hunting dog (genus Lycaon) are not classified as members of the genus Canis, but by genotype they are closer to dogs, wolves and coyotes than are the two genus Canis jackals – the Side-striped jackal (C. adustus) and the Black- backed jackal (C. mesomelas). In 2015, a study of mitochondrial genome sequences and nuclear genome sequences of African and Eurasian canids indicated that extant wolf-like canids had colonized Africa from Eurasia at least 5 times throughout the Pliocene and Pleistocene, which is consistent with fossil evidence suggesting that much of the African canid diversity resulted from the immigration of Eurasian ancestors, likely coincident with Plio-Pleistocene climatic oscillations between arid and humid conditions.

Clade D contained sequences from 2 Scandinavian breeds (Jamthund, Norwegian Elkhound) and were the sister group to another 14,500 YBP wolf sequence also from the Kesserloch cave, with a common recent ancestor estimated to 18,300 YBP. Its branch is phylogenetically rooted in the same sequence as the "Altai dog" (not a direct ancestor). The data from this study indicated a European origin for dogs that was estimated at 18,800–32,100 YBP based on the genetic relationship of 78% of the sampled dogs with ancient canid specimens found in Europe. The data supports the hypothesis that dog domestication preceded the emergence of agriculture and was initiated close to the Last Glacial Maximum when hunter- gatherers preyed on megafauna. The study found that three ancient Belgium canids (the 36,000 YBP "Goyet dog" cataloged as Canis species, along with Belgium 30,000 YBP and 26,000 YBP cataloged as Canis lupus) formed an ancient clade that was the most divergent group.

The route by which the Falkland Islands wolf was established in the islands was unknown for a long time, as the islands have never been connected to the mainland see figure 3 and there are no other native land mammals.But even though the study has gone some way to clarifying the evolutionary origins of the Falklands wolf, the species still represents a great bio-geographical conundrum because the Falklands have never been connected to the South American mainland and no other land mammals – not even small rodents – have managed to live there. No other oceanic island as remote as the Falklands has a native canid; the island fox of California in the US and Darwin's fox of Chile both inhabit islands much closer to a continent. Berta and other authors suggest that it was unlikely that the wolf's ancestors could have survived the last Ice Age on the Falklands and they must therefore have arrived later, within the last ten thousand years, crossing a wide expanse of the South Atlantic.

Further doubts over its being conspecific with the golden jackal of Eurasia arose in December 2002, when a canid was sighted in Eritrea's Danakil Desert whose appearance did not correspond to that of the golden jackal or the six other recognized species of the area, but strongly resembled that of the gray wolf. The area had previously been largely unexplored because of its harsh climate and embroilment in the Eritrean War of Independence and subsequent Eritrean–Ethiopian War, though local Afar tribesmen knew of the animal, and referred to it as wucharia (wolf). The animal's wolf-like qualities were confirmed in 2011, when several golden "jackal" populations in Egypt and the Horn of Africa classed as Canis aureus lupaster were found to have mtDNA sequences more closely resembling those found in gray wolves than those of golden jackals. These wolf-like mtDNA sequences were found to occur over a 6,000 km wide area, encompassing Algeria, Mali and Senegal. Furthermore, the sampled African specimens displayed much more nucleotide and haplotype diversity than that present in Indian and Himalayan wolves, thus indicating a larger ancestral population, and an effective extant population of around 80,000 females.
