I have been informed that we have had more than 3 dogs with aggression issues and after thinking about it that's right. Mike has dealt with each and every one of them. Trust me on this one, we have seen just about everything there is to see when it comes to behaviors. I am here in front of everyone on Pet Talk to say that I accept any and all liability to Chewy. I am even offering to drive out to PA and pick him up. He would be crated when we aren't home until he has been evaluated by us and the other poochies. I trust he won't be alpha, but, I think he'll try. He will learn quickly that the only true alphas in this society is Mike and me. Some how I would think that 20 dogs who already make up a pack would be slightly daunting for one medium size pooch.
