It's wonderful you are working with him to help his fears. As far as the groomer who grabbed him, and then hurt him by cutting the nails too short as well-- I would be very careful with this. If they can't appreciate what you are telling them about making it a positive experience, then the next time they grab your dog like that take the dog back from them (and explain why) and find someone else to trim his nails. A few bad experiences with nail trimming, or with the groomer in general, and they will remember it their entire life. You want all of these new things to be positive. Good luck!
