Evolution
The Dog linage began 37 million years ago in North America in predators that had distinctive pairs of shearing teeth and ran down prey. Early canids reached Europe seven million years ago.  

Eight million years ago a powerful canid called Epicyon attacks a horned herbivore. Epicyon were the size of large wolves and lived in North America.

The Eucyon, a fox-size canid, moved west from North America around 4 to 6 million years ago and gave rise to most modern canids, including wolves, coyotes, and jackals.
