First, I turned to natural history literature. I found that the wolf, as we know it today, evolved from carnivores and roamed the earth over one million years ago. During those early years of man and womankind wolves were always competitors with humans for the same prey species. Wolves have a strong social nature. Through gestures and body movement, they communicate their feelings.
Wolves like to howl as a pack for several reasons.
It may be to encourage their closeness, to celebrate a successful hunt, and to tell other packs to keep away. The lone wolf, a younger male, is usually in search of his own territory and a mate. He will skirt the territories of others but rarely howl. While the wolf pack is led by an Alpha male and Alpha female, each wolf assumes his or her share of responsibility for the welfare of the pack. From the early playful experiences with the older wolves, pups are carefully trained to assume their part of the leadership of the pack as if their life, and that of the pack, depends upon it.
