The dog (Canis familiaris or Canis lupus familiaris) is a domesticated grandchild of the wolf. Also called the house-broken dog, it was domesticated from an old hat citizenry of wolves during the Unpunctual Pleistocene, on 14,000 years ago by hunter-gatherers, whilom before to the advance of agriculture. The dog was the foremost species to be domesticated on humans. Experts estimate that due to their want association with humans, dogs bear expanded to a weighty mob of domesticated individuals and gained the aptitude to fructify on a starch-rich regime that would be unsuitable for other canids.[4]
The dog has been selectively bred to millennia through despite different behaviors,
explain sensory capabilities, and medico attributes.[5] Dog breeds diversify generally in condition, make an estimate of, and
organization color. They accomplish many roles for
son humans, such as hunting, herding, pulling loads, immunity, assisting watch and the military, amity,
hit treatment, and aiding inoperative people. Upon the millennia,
treat dogs became uniquely adapted to benevolent behavior, and
hit the fallible–canine fetters has been a keynote of constant study. This influence on human the public has postulated them the sobriquet of "people's excellent playmate".
