We have the same issue in Orangeburg county. Most of the dogs look like they have some pit in them and are most concentrated on the corner of the farm bordering a small trailer park. Mostly no collars and they haul ass if you run across them. We have found several deer that appeared to have been killed by dogs, one of which was a doe with two grown fawns ripped out of her. We put a trail cam on one dead doe and 9 different dogs fed on her. I've caught two trying to catch coyotes and released them both. One of them really wanted to bite me; the other wagged it's tail when I pulled up. I hate them but I don't want to lose any sleep at night.
