I have the same problem sometimes. I've taken to toting the shotgun out on days that I know the dog hunters with be setting them loose. They can't shoot within 300 yds of my house and can't shoot onto property they don't own, so that pretty much means that they can't shoot anything the dogs chase out on my road. If they chase another deer by my stand or onto the property I hunt, I'm going to shoot it and take it home. If crosses the road, it's mine, no questions asked. So, if they choose to waste their ammunition and time they can. If they argue, they can argue with the game warden and county police. The law is on my side and they know it, so if they choose to ignore the law it can become their problem.
