My question would be, when Perry acts in this manner, what is your response?

I should probably let one of the experts chime in first, but I have seen some dogs act aggressively and their people just stand there dumbfounded. When Hannah goes "too far" trying to intimidate Tucker, I am all over her like a wet blanket. Voices are raised and I do carry on about the matter so there is no doubt in her mind who is in charge and that type of behavior is not to be tolerated. I do not hit my dog but the "Fear of Mom" is definately communicated.

Now the experts can chime in.
