Wolves as pets and working animals

Wild wolves are sometimes kept as exotic pets, and in some rarer occasions, as working animals. Although closely related to domesticated dogs, wolves do not show the same tractability as dogs in living alongside humans, and generally, much more work is required in order to obtain the same amount of reliability. Wolves also need much more space than dogs, about 25 to 40 square kilometres (10 to 15 sq mi) so they can exercise.
