Well, I really don't think that anyone criticized you at all, just giving opinions and advice which you asked for. I thik the behaviorist is a great idea. Also a choke or prong collar would be a good idea, since putting Roscoe on a prong I can walk him without my arm feeling like it's going to fall off Roscoe can be protective of me sometimes too, but the prong keeps him from pulling or lunging.
