I love dogs and have always had them as pets. But I keep track of them for their sakes and out of courtesy. To me, its just common sense to control your dogs. If one of my dogs got loose and was killed it would bum me out but thats just the way it is. I've had the exact problem you are talking about. I've hunted a small tract the last few years and its always had plenty of deer. Last year no deer. But sure had 2 or 3 dogs that seemed awful comfortable running around the place the first day of season. I didn't shoot any of them but I will this year if I get the chance. One of them looks like he's part pit and he scared the crap of me a few times because I'd turn around and there he'd be about 5' away. He never growled or anything but I ran at him a few times and he'd run away just a bit and then come back. I finally pitched a rock at him one day and pegged him in the ribs. I heard a grunt/yelp and didn't see him for a few weeks but then saw him again. Sometimes it was just him and other times he'd have 1 or 2 others with him. I pretty much quit going out there. I wasted a lot of time last year setting up a few stands, trimming lanes, etc., all for nothing. So yes, I'll end that business this year if it happens again. I won't like it but I'll do it. The land owners are pissed, too. I told them about it and then they were out there a few times and had the same thing happen. They told me if I saw them again they'd appreciate any help with the matter.
