I've hunted in Va where dogs are legal, not a big deal as far as hunting deer go. What do you think those dogs are doing, just chasing the deer out of your place and not chasing them back? If there wild they won't last long.
Wild dogs don't bother me, in fact they've moved deer to me. They do make a quiet hunt like being stuck in a room with squabbling women though, that gets'm as close as can be to a vet hole sometimes.
