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.
Dingo
Similar to other canids, a dingo pack largely consists of a mated pair, their current year's offspring, and occasionally a previous year's offspring. Dominance hierarchies exist both between and within males and females, with males usually being more dominant than females. However, a few exceptions have been noted in captive packs. During travel, while eating prey, or when approaching a water source for the first time, the breeding male will be seen as the leader, or alpha. Subordinate dingoes approach a more dominant dog in a slightly crouched posture, ears flat, and tail down, to ensure peace in the pack. Establishment of artificial packs in captive dingoes has failed.
