Wolf-pack

Pack is a social group of conspecific canids. Not all species of canids form packs; for example, small canids like the red fox do not. Pack size and social behaviour within packs varies across species.

African wild dogs (Lycaon pictus) live and hunt in packs. Males assist in raising the pups, and remain with their pack for life, while the females leave their birth pack at about the age of two and a half years old to join a pack with no females. Males outnumber the females in a pack, and usually only one female breeds with all of the males. African wild dogs are not territorial, and they hunt cooperatively in their packs, running down large game and tearing it apart. They cooperate in caring for wounded and sick pack members as well as the young.

Gray wolves (Canis lupus) usually live in packs which consist of the adult parents and their offspring of perhaps the last 2 or 3 years. The adult parents are usually unrelated and other unrelated wolves may sometimes join the pack. Wolves usually hunt in packs, but they hunt singly in the spring and summer when there is plenty of prey available.

Black-backed jackals (Canis mesomelas) and coyotes (Canis latrans) have a single long term mate, but they usually either hunt singly or in pairs. Both parents care for the young, and the parents and their current offspring are the pack. They occasionally cooperate in larger packs to hunt large game.

The Ethiopian wolf (Canis simensis) has different social behavior from the gray wolf: pack members hunt alone for rodents, and come together mainly to defend their territory from other packs.

Domestic dogs (Canis lupus familiaris): Domesticated dogs have had humans as part of dog social structure for at least 12,000 years, and human behaviour is not the same as wolf behaviour. Studies of dog behaviour include studies of dogs and their interactions with humans, and "dumped" or "road" dogs that were raised by humans and then left to fend for themselves (e.g. The Tuscany Dog Project).
