A female wolf is pregnant for 63 days or less. Wolves could have five to six pups in a litter. The mother digs a den so she could put her pups in. Pups come out of the den by the time theycan see and hear very well. By the time they can see, they begin to look around the den.
Pups can hear and see well by the time they're three weeks old.
Now they can go farther and beyond the den. Almost any environment can be a home for a wolf. Two places where wolves live are desserts of the United states and the dense, wet forests of southern-east Mexico. What a wolf needs in its environment is a place to escape its enemies. Arctic Wolves live on the Arctic tundra.
