Pack (canine)
Animals which typically predominate over others are associated with the term "alpha". Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition.
Julie's Wolf Pack
When it comes time for pups to be conceived, Sweet Fur Amy refuses to mate, feeling that with her confined to the den, the pack would fight and split up. It is instead Uqaq who becomes a mother, mating with Wind Voice. Raw Bones convinces Uqaq to have her pups at the den site near the Colville River that he has coveted. She goes there, where she gives birth to a litter of nine pups.
