Dogs began with the domestication of the wolf in Western Europe 11–16,000 years ago. This is during the time when humans were hunters. Proto-dogs may have taken advantage of carcasses left by early humans after hunting, as well as helping to capture prey and providing protection from larger predators. Dogs got the nickname "man's best friend" in human society.

Wolves and their canine descendants, living near human camps would provide them with significant benefits such as greater security, more reliable food sources and more chance to breed. At the same time, humans must have got huge benefits from the dogs living near their camps. The dogs used to clean up the waste food and they would have alerted the camp to the presence of predators or strangers.
