When I was in high school, our neighbor had a dog that would room freely and get into our garbage and pull clothes off the line. Not only that, he was mean as Hell! So, I told the neighbor that he needed to keep his dog out of our yard. When he asked how he was supposed to do that, I told him that I had no idea, but I was sure that he could figure something out. about a month later, i was home by myself and the dog was getting into our trash so I shot the dog in the rear foot. the next day, Mr. Neighbor asked me if I shot his dog, complaining that it cost him more than $300 in vet bills (Mid 1980's). I told him that I shot A dog, but it couldn't have been his dog because we'd agreed that he'd keep HIS dog out of our yard. For some reason, nothing more was said.
Reminds me of the story my friend told me. except his story he gave the neighbor one last warning and said his dog will be shot if he comes again. well the dog did and my friend shot and killed the dog. Neighbor called the cops on him but cops didn't do anything.
