Wolves are shy, submissive animals.
There has never been a documented case in North America where a healthy wolf has ever attacked a human. Like some dogs, they are very territorial and will claim certain den sites, travel routes and feed grounds as their own. Adult wolves have the ability to regulate their body temperatures and can, therefore, adapt to different climates. Very young pups, however, cannot regulate their body temperatures and must stay close to their mother for warmth. Wolves from the Arctic Tundra are usually white and have long, thick fur to protect them from the cold.
