What I really believe is, if dogs hear gunfire in the field while they're excited and having fun, it doesn't bother them. My setter Ike hates fireworks, thunderclaps and other loud noises but gun shots in the field don't faze him, because he associates them with a warm, dead bird on the ground. So, on Monday I took the dogs on afternoon run at the local marsh, knowing that early duck season is in and we would hear some guns going off. As Jed ran around enjoying himself he heard several gunshots, including a couple that were fairly close. He looked up, noticed that neither Ike nor I reacted, and went back to what he was doing, which was sniffing a catfish carcass.
