what would you do?

On the other hand if the dog was running free, how can anyone be certain who the daddy dog is. Seems like he should have pinned his dog up, but he didn't. It unfortunate but he can do what he wants with his dog and the pups. Is he just an a$$ b/c he let her run loose or are there other reasons? I can usually get along with anybody, if I thought I could talk to him without starting a pissing contest, I would call him up or stop by. If I thought it was going to cause problems, I'd leave it alone. Like previously said, you may try to take call the law if her coming on your property continues to cause you problems.
