This den is not shared by the rest of the pack, who by that time are in their summer den. In their dens, wolves sleep, sometimes even eat or play, though most of the eating is done where the animal was caught. The Arctic wolf lives on the Tundra. In winter, which is almost the whole year in the Arctic, the ground is covered in snow. In the summer though, the ground has plants, berries, and lichen.
Wolves are hunters.
They eat caribou, small walruses and musk oxen. Like many animals, pups have their first meals off their mothers milk. When they are ready to actually eat, the pack members digest their food, and regurgitate it for the pups to eat. This is because the pups can't digest their own food yet. The pups start to develop their hunting skills by catching insects and small rodents.
