The typical lifespan of dogs varies widely among breeds, but the median longevity (the age at which half the dogs in a population have died and half are still alive) is approximately 12.7 years. [ 73 ] [ 74 ] Obesity correlates negatively with longevity with one study finding obese dogs to have a life expectancy approximately a year and a half ...
The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. 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 ...

The dog population experienced relative stability from 1987 to 1996, before seeing a yearly increase of 3-4% since that time.

[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. [33 ...
The domestic dog is the first species, and the only large carnivore, to have been domesticated. The first dogs were certainly wolflike, but the phenotypic changes that coincided with the dog–wolf genetic divergence are not known. [15] Dogs are the most variable mammal on earth with around 450 globally recognized dog breeds. [2]
