| I think that you have to realize that he may not be growling out of aggression but may be growling out of fear. Are his hackles raised when he growls? does he step towards or away from the target, how is he with other "scary" things, loud noises, new places, cars etc?
Also, never roll a dog for play biting. I have rolled Lexx a few times, but not to show dominance, just to get him used to being handled in all ways and trust me, I don't know if i even would have done it knowing what i know now. Rolling is NOT a fix for this behavior and will likely only make it worse in the end.
You need to find yourself a trainer that is familiar with DOGS period, even better if they are familiar with dobermans.
