See if only everybody did what you do bryant1. It is the owners responsibilty to control and look after there dogs. All the problems Ive ran into on our land has been non collard dogs lately. But two weeks ago I was sittin on the ground and a walker and lab came runnin through the woods. Now the walker was trailing something and the lab was just followin...he was trackin me haha! They got to me I stood up and they ran over n sat down beside me. The walker was not collard but healthy and the lab looked like it escaped from a 5 star pet resort. I just sat there and they did to but "we" didnt see anythig lol. They followed me out when I left and I havnt seen em since. Bottom line is if they are affecting your hunting over periods of time shoot em.
