Most lone wolves die within a year or two after being outcast. The pack divides their duties, works together, and protect each other. Early explorers encountering them found them to be very gentle and shy. Healthy wolves have never been known to attack humans. The only time attacks happen is when rabies are involved.
Wolves hunt the weak, old, and sick animals.
They keep the balance. They are not the threat many movies and books have made them out to be. They have been misunderstood like most Native Americans have been misunderstood. I hope this has stirred an interest in these beautiful animals. Here are some web sites I've found and enjoyed about wolves.
