A wolf has dense, warm fur, so can survive extreme cold. A wolf's sense of smell is up to 100 times more sensitive than humans, it can hear up to a distance of 10 miles and has good night vision. Behaviour Wolves are illusive, avoiding contact with humans wherever possible. Wolves are playful animals and play amongst pups helps to develop muscles, hunting skills and to establish hierarchy. Society Wolves live and hunt in very closely bonded, well-structured family packs, led by a dominant, breeding pair, the 'alpha male and female'.
Wolves sometimes mate for life.
There is a well defined 'hierarchy' within the pack and every member of the pack has a social rank. After a nine week gestation, the alpha female gives birth to up to seven pups who at first are dependent on her milk. After a month the pups emerge from the den and other members of the pack act as 'helpers', caring for the pups and giving them food and attention. Wolf Campaign .
