The dog is a domestic animal that likely travelled a commensal pathway into domestication (i.e. humans initially neither benefitted nor were harmed by wild dogs eating refuse from their camps). [ 23 ] [ 26 ] The questions of when and where dogs were first domesticated remains uncertain. [ 20 ]
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]

A study of the estimated bite force at the canine teeth of a large sample of living and fossil mammalian predators, when adjusted for their body mass, found that for placental mammals the bite force at the canines (in Newtons/kilogram of body weight) was greatest in the extinct dire wolf (163), followed among the modern canids by the four ...

The domestic dog is a divergent subspecies of the gray wolf and was derived from an extinct population of Late Pleistocene wolves. [ 8 ] [ 31 ] [ 32 ] Through selective pressure and selective breeding , the domestic dog has developed into hundreds of varied breeds and shows more behavioral and morphological variation than any other land mammal.
Heller's names and the designations he gave to various jackal species and subspecies live on in current taxonomy, although the genus has been changed from Thos to Canis. [5] The wolf-like canids are a group of large carnivores that are genetically closely related. They all have 78 chromosomes. The group includes genus Canis, Cuon, and Lycaon.
