mdbohuntr - I'm glad to see you are learning from me already!!
Another thought on the dog: If the owner is unknown, or doesn't want to help with controlling the dog, and if there were not sufficient legal options, then I would also have to look at the welfare of my deer herd. This is absolutely the WRONG time of year to have a herd of deer stressed out by loose running dogs. With that in mind, I would get it resolved quickly if possible, but if I had no other feasible alternative, I'd rather shoot the dog than to allow him to cause a lot of stress to my deer. I don't want either to happen, but it's like someone breaking into my house. I don't want to shoot them , but I would before I would let them harm my family. An extreme analogy, I know, but it gets the idea across.
