Wolves are social animals that live in family-like units called packs.
Of all their calls, howling is the only one that works well over long distances.
The way the tail is held is a very important part of a wolf's body language; submission, dominance, aggression or fear can be detected from the position of a wolf's tail.
Wolves eat grass as a purgative and other vegetable matter like nuts or berries.
Wolf pups introduced to humans instead of wolves when one month old will bond to people at this time.
Wolves need an average of three to 10 pounds of meat each day.
Wolves can travel distances from 10 to 30 miles in search of food by trotting along at five miles per hour. They can run short distances at 25 to 35 miles per hour when chasing prey.
