I got excited for a moment, then I read that they will still fight for "alpha". Wolves don't fight for alpha. There is no such thing as alpha with wolves. There's the breeding pair, who are the parents, and almost always everyone else in the pack are their offspring. The offspring respect their parents and never fight them for "alpha" status. When offspring want to form their own pack in the wild they leave their original pack to find a mate. That is leave, as in they choose to do so and are not chased out. In captivity, unless they are traded out they obviously can't leave, but they wouldn't fight their parents for control of the pack.
I'm ok with wolves fighting if you introduce an outsider into their pack. But the members of the pack, i.e. the breeding pair and their offspring should not fight. Or at least if they do fight, please make it so they don't get serious injuries because of it.
