I had a friend with the same problem. The neighbor let their hound run his woods at will. Every time he was on his deer stand the dog would come running by. He did all he could do to ask the owner to keep his dog at home, but he was ignored. So one day, he took things in his own hands and solved the dog problem. His only mistake was he left the evidence where it could be found. As it turned out he ended up in more trouble than it was worth. So if you do decide to thin the dog population, be SURE no one ever knows.
