Not only the idea of the Alpha male and hierarchical structure in wolf packs is completely outdated in favor of a more family-based structure with a breeding pair as leaders, but also female Alphas exert dominance other females the same as males do to other males. But not only that; wolf packs are almost always matrilinear, which means that the mother is the one determining the lineage, not the father. In fact, when the Alpha female dies, her mate often leaves the pack to look for another female, while one of her daughters become the next Alpha.
But hey, I’m not trying to bore you to death with a canine behavior lesson. What I’m trying to say is that female Alphas aren’t “rare”, as many books portray, but more like the opposite. Yet, in the werewolf genre, the made-up hierarchies keep portraying females as followers, and very rarely as leaders. I find this very sad, and even more when most of these stories are written by women and have female main characters. There’s nothing wrong with not being the Alpha, I just want to remind you that there’s nothing in the wolf nature that implies the leader has to be a boy.
