Aw Payson, Lucky has the same problem. We brought him to a relatively quiet training class and he went beserk! I pulled him out and we're content with training and socializing on the dog trails, which are very quiet and peaceful with a minimum of disturbance. Do you have any of these trails near you? They really did help with Lucky's fear. Also, I just wanted to add that the minute Payson starts to "go deaf", it's time to back up to a quieter place. You made the right choice

Have you bought "The Cautious Canine" by Patricia McConnell? It's a short booklet that costs, oh say, 5$, but it is so worth it!
