The first time my dog was exposed to shotguns she sat in the truck and watched the other dogs hunt. After an hour or two watching she wanted out so bad that she never noticed the second shot. I also shoot alot of clays in the backyard. At first I kept her up close to the house and far enough away that the noise didn't scare her. Pretty soon she was sitting under the tailgate by me. Gunshots don't bother her a bit any more. Now they mean bird down and she's looking the direction I shot.
