Dire Wolf

The Dire Wolf (Canis dirus) was a large canine predator that lived in Pleistocene North America. Fossil evidence suggests that they lived much like modern gray wolves

Environment
Dire Wolves lived on a plain full of potential prey; as well as rival carnivores. Smilodon, the Sabre-toothed cat, was perhaps its greatest concern. Other threats would have been the Short-faced Bear and American Lions.
