What came before dogs?
An extinct Late Pleistocene wolf may have been the ancestor of the dog. The dog is a member of the wolf-like canids. The genetic divergence between the dog’s ancestor and modern wolves occurred between 20,000 and 40,000 years ago, just before or during the Last Glacial Maximum (20,000–27,000 years ago).
How did dogs survive before they were domesticated?
Dogs were domesticated when ice sheets covered much of northern Eurasia and the climate was colder than today. During this time, humans and wolves would have competed for food, as both are top predators. However, wolves can survive on nothing but lean meat – which contains protein and little else – for months.
Why are dogs considered 7 years to our 1?

What were dogs used for a long time ago?
When livestock were domesticated about 7,000 to 9,000 years ago, dogs served as herders and guardians of sheep, goats, and cattle. Although many still serve in these capacities, dogs are mainly used for social purposes and companionship. Today dogs are employed as guides for the blind and disabled or for police work.
Where did dogs come from originally?
Thanks to DNA, we can see that dogs evolved from wolves somewhere between 19,000 and 32,000 years ago in Europe, but the genome of living dogs shows that the split took place in Asia around a thousand years earlier.
