Several years ago I was in Arkansas where running the deer with dogs was still permitted. I had three smaller hounds run through and piss on the legs of the feeder before trotting off down the trail. They almost got fed some lead but I noticed all three had orange collars on. We were on private land so there shouldn't have been any dog hunters out there, but I also know that dogs don't understand the term "private property" so they got a one day pass. If I had seen them a second time in the next couple days, they would have taken a quick trip across the rainbow bridge.
I hog hunted with my dogs and I know the costs that go into them, but I also know that its MY responsibility to make sure they are taken care of and part of that is keeping them out of situations where they can get hurt by people, ie running on property where they aren't allowed to be. A dog owner can only be mad at themselves if their dog got hurt while on somebody else's property, especially if you know the properties around you are dangerous areas for your dog.
