Social structure

Wolves function as social predators and hunt in packs organized according to a strict social hierarchy and led by an alpha male and alpha female. This social structure was originally thought to allow the wolf to take prey many times its size. However, emerging new theories suggest the pack strategy has less to do with hunting, and is based on reproductive success.

The size of the pack may change over time and is controlled by several factors, including habitat, personalities of individual wolves within a pack, and food supply. Packs can contain between two and 20 wolves, though an average pack consists of six or seven. The hierarchy of the pack is relatively strict, with the alphas at top and the omega at the bottom. The hierarchy affects all activity in the pack, from which wolf eats first to which is allowed to breed (generally only the alpha pair).

New packs are formed when a wolf leaves its birth pack and claims a territory. Wolves searching for other wolves with which to form packs can travel very long distances in search of suitable territories. Dispersing individuals must avoid the territories of other wolves because intruders on "owned" territories are chased away or killed. This possibly explains wolf "predation" of dogs. Most dogs, except perhaps large, specially bred attack dogs, do not have much of a chance against a wolf protecting its territory from the unwanted intrusion.
