@alextheboss: No. Rottweilers are smaller, slower, less powerful, and less experienced. They have a cap bite force of 350 psi, wolves can reach 1,200 when defending themselves.
If Rottweilers would hurt Bruce, Wolves will kill him. Also, Bruce likely still would try to knock out the wolves, since I don't think he killed the Rottweilers and his no-kill rule doesn't seem to have too many limitations.
