He's a bandog.
No, I'm saying this particular aggression I'm talking about is in reference to firing guns or fireworks (and when he sees a decoy for bitework), but it's not limited to that. He also attacks lawn mowers, weed wackers, chain saws, etc. Those were corrected strongly for because my husband wasn't amused by it and he really tries to rip the tires off both ride on and push mowers while they're on and it's dangerous to him :nono: My female bandog was similar with the lawn equipment, just not as extreme or strong in dismembering it. She's a much smaller dog. Gun fire though never made her act that way, or fireworks.
Actually, now that you mention it, I do have a gun shy dog. My pointy eared mix. He has weak nerves. I don't know why I always forget about him I'm not interested in fixing him though. It's not worth the effort. I can't/won't work with weak nerves.
I've heard of other people trying to neutralize the gun shy issues for trial and it didn't work well.
I'll take your word on the efficacy of Koehlers test. My trainer went into a very long discussion on the ways to introduce gunfire and the ways introducing it could go wrong. For my female, I didn't introduce gun fire during work until the trial itself and she acted appropriately.
Do you think your rottweiler was introduced to gun fire during bitework and he sees it as a cue he's going to get to work?
