I've lived next to a non-stop barker. Of course the owner never understood what was wrong because she was never there to hear the barking. When she came home, the dog stopped barking. And when it wasn't barking it was whining because she left a great dane locked in a small apartment for 16 hours at a time, alone. I love animals, but I'm allergic to them. I hate many of these self-centered 'animal lovers' who think just because they have a pet, they are 'entitled' to let dogs bark all day long or let them poop everywhere without picking it up or run off lease. No, I don't want your animal jumping on me. I don't care if you think he's 'gentle and wouldn't hurt a flea'. And your dog does bark all day long!
So was wrong to shoot the animal, but I sympathize with him. It's overwhelming to hear an animal bark constantly, even if it's not all day long. Both should have been given a fine, and made to stop shooting dogs, and stop letting their dog bark. Sometimes the noise can drive u nuts!
