4. The child rearing of wolf

Wolves has an interesting way of raising their young. When a female wolf is ready to give birth, she digs a hole. Within this hole, she has her babies. While she is taking care of these babies, other wolves bring her food. After they get a little older, the mother can leave them while she goes off to hunt with other members of the group. Then, instead of the mother, another female will stay behind to guard the young wolves.
