Dog Facts

It is believed that the ancient ancestor of the dog was the wolf and that they began to bond with humans as a way to get food.

The wolf offered a level of protection from other predators and in return had the chance to eat the food scraps.

Over the years, the dog was domesticated and the bond between humans and dogs has been so great that humans began to breed them for specific abilities, talents, and even appearances.
