At this point, I would recommend the dog be evaluated by a professional trainer. I don't know what you did but trying to fixa problem can potentially create more problems especially for a new trainer. Gunshyness is not an easy problem to fix. It can take months if it can be fixed at all. You run the risk of accidently introducing some strange behavior or even worse, yelling and punishing the dog out of frustration. As an example, a friend's young brittany was never introduced to the gun properly. He didn't use birds. While out on walks, he simply fired .22 blanks then called the dog in to give her treats. Seems like a fineidea - gunfire = treats but whenwe went hunting, the moment someone fired a shot, the dogbolted to the owner's side. The dog wasn't scared of the shot but thought that the sound was for, "come here immediately!".

Hopefully, you won't listen to the person(s) who initially told you how to introduce the gun in the first place. A good trainer can tell you how long it will take and what you need to do.
