Also called the domestic dog, it was selectively bred from an extinct population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans , over 14,000 years ago and before the development of agriculture .

The genus Canis (Carl Linnaeus, 1758) was published in the 10th edition of Systema Naturae [2] and included the dog-like carnivores: the domestic dog, wolves, coyotes and jackals. All species within Canis are phylogenetically closely related with 78 chromosomes and can potentially interbreed. [4] In 1926, the International Commission on ...
All canids have a similar basic form, as exemplified by the gray wolf, although the relative length of muzzle, limbs, ears, and tail vary considerably between species. With the exceptions of the bush dog, the raccoon dog and some domestic dog breeds, canids have relatively long legs and lithe bodies, adapted for chasing prey. The tails are ...
Its taxonomic classification is debated as indicated by the variety of scientific names presently applied in different publications. It is variously considered a form of domestic dog not warranting recognition as a subspecies, a subspecies of dog or wolf, or a full species in its own right.

A prairie dog town may contain 15–26 family groups, [20] with subgroups within a town, called "wards", which are separated by a physical barrier. Family groups exist within these wards. Most prairie dog family groups are made up of one adult breeding male, two or three adult females, and one or two male offspring and one or two female offspring.
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.
