Origin:The first canids arrived in Europe seven million years ago, but it was Eucyon, four or six million years ago , that gave rise to most of today's canids, such as wolves, coyotes, and jackals.

Fun facts: Wolves have an extraordinary sense of smell that allows them to hunt at night . Wolves (canis lupus) are the largest species in the canid family. They tend to be quite shy and suspicious of humans because, unlike dogs, they have not been domesticated.
