Wallpapers For Dogs

The dog derived from an ancient, extinct wolf, and the modern grey wolf is the dog's nearest living relative.

The dog was the first species to be domesticated, by hunter gatherers over 15,000 years ago, before the development of agriculture.

Their long association with humans has led dogs to be uniquely adapted to human behavior, leading to a large number of domestic individuals and the ability to thrive

on a starch-rich diet that would be inadequate for other canids.
