Wolves can adapt to very cold climates and keep warm in winter because they have two coats of fur. They can happily sleep in blizzards under the snow. There is a thick, downy undercoat for insulation while an overcoat of long, guard hairs repels water and snow. The undercoat sheds in the spring and grows back again in the fall and winter.
