Second, because feral dogs do not exhibit the classic wolf-pack structure, the validity of the canid, social dominance hierarchy again comes into question. For the purposes of annual population surveys, the Washington Department of Fish and Wildlife (WDFW) defines a wolf pack as two or more wolves traveling together in the winter. If true, it implies that social behavior-even in wolves-may be a product more of environmental circumstances and contingencies than an instinctive directive. A pack is considered the fundamental unit of wolf social organization, and it is typically defined as a cohesive family unit that uses an established territory. First, because it does not seem to occur in the wild, this article suggests the strong dominance hierarchy that has been described for wolves may be a by-product of captivity. This article questions the validity of this perspective on 2 principal grounds. One recommended solution has been for the owner to endorse and enforce a particular dominance hierarchy because, on the wolf pack model, aggression is minimized when the structure of the hierarchy is clear, strong, and stable. This view suggests that aggression problems among dogs are natural expressions of conflict that arise whenever dominance status is in contention. Wolfpack is a realistic, first person, co-op U-boat game where one or multiple crews of players man the stations of a highly detailed German type VII U-boat.

A popular perspective on the social behavior of dogs in multiple-dog households sees the dogs' behavior as reflecting the sociobiological laws of the rigidly structured dominance hierarchy that has been described for wolf packs.
