Chukchi Husky
Lone Wolf
I also find that a lot of the alleged conservation and research work done by zoos and aquariums to be merely bottom-barrel efforts meant to cover their own ass:
The research can end up being wrong. The first serious research and study into wolves begun during the early seventies. What the researchers did was observe random wolves brought together in captivity and how the wolves interacted with each other. This is where the idea that wolves form hierarchy based packs led by an alpha comes from. Later observation with wolves in the wild showed that this idea is incorrect, wolf packs are more like an extended familym but people still continue to believe it to this day.
