The highest rank is the Alpha male, then the Alpha female, then the less strong wolves, and then the pups. The Alpha male of the pack is almost always the strongest and most fearless, so when the Alpha male gets scared, the other wolves in that pack are too. This arrangement helps prevent fighting among the pack. A wolf will not usually stay with the pack that it is born in its whole life. After a wolf is ready to mate, it will leave the pack, find a mate, and make a pack with some other unmarried, or married wolves and they will make a pack together.
Wolves can live almost anywhere.
They can live in the North or South, Tundra or Tree line, and even in mountains or around swamps. Whatever environment wolves are living in, they will live in a den. A den is a place in a hill, or in rocks where a wolf will live with its pack. Wolves make the dens by digging with their paws. They have a winter den, which is very warm, and a summer den.
