If there is abundant prey for pack to feed its territory,the pack will stay there for many years. Once a pack is settled in a territory, its wolves can begin raising their families. Wolf family members always show a great deal of love and affection for each other. A wolf family is not like a humans family. Wolves are usually mates for life.
Young wolves stay with their parents until they are several yeas old.
However scientist agree that wolf packs how because they are staking out their territory and telling other packs to stay away. About two or three weeks before pups are born the pregnant female begins to dig a den. The den will become the center of the packs activities for the next twelve to fourteen weeks. Hillsides provides good den sites, for the parents can observe all that is going on around them. Other dens are built at try base of large trees, at the bottom of dead trees that have been uprooted by the wind, in old rock-caves and in old fox dens and beaver lodges that are dug out by the wolves.
