Wolves can live in a wide range of habitats like tundra, woodlands, forest grasslands, and deserts. Wolves live in Wolf Dens. Wolves only use dens when they have young pups that are not yet able to travel with the pack. Wolf dens are usually found near water and sometimes a south facing slopes.They can be dug under a boulder, in tree roots, or in cut banks, hollow logs or other strong natural structures.
