I don't know much about coon dogs, but they seem to be extremely driven dogs and I could see why would could be difficult to get them called off of a trail. That being said I think that if they would happen to go onto other land you should leave your weapon behind and go in and get your dogs after the coon is treed. I also think that it would be a good idea to talk to the land owner around the land that you do hunt and explain to them what happens when your dogs follow a trail and get away from you. Tell them that you are not planning on hunting the land, but that you may need to go and get your dogs. I just do not think that it is a good idea to leave your dogs in the woods over night. Seems like a good way to lose a good dog.
