Eh, I'm actually fine with Zwei's power levels. There are more than enough games be it an RPG or MMO where you carry around a super high level pet that can easily roll a level 30 or 40 to death. And given that this dog is probably from Taiyang/Summer Rose's generation it probably has encountered fights far more grueling than what Team RWBY has faced so far.

Hell, it might even be an offspring of the pet who died along with Summer or something and thus has enhanced stats I'll believe it. Monty emphasized again and again that RWBY is constructed with the idea of a game at its core.
