I'm also opposed to deer hunting with dogs. I guess a lot depends on where dog hunts are taking place as to whether it's an ethical practice or not.
Dog hunting is not as popular here in Ms as it used to be, as most hunters that respect other folks lands and posted signs have long since given up dog hunting in favor of still hunting.
Another thing that makes the "dogs can't read posted signs" statement offencive to me is that most hunters are now using breeds of dogs such as the Running Walkers" that are known for running deer unlimited distances. Seems to me that if the dog hunter even intended to have range control of his hounds he would opt for other breeds. Face it, deer dog hunting in the best case scenerio is done with the intent of busting deer off private land and push them to where it is legal to shoot.
By experiance I have found deer dog hunters to be the most unethical of all the hunters, and an imposition to other hunters and non hunters alike.
I regularly write my congressman expressing my opinion of deer dog hunting, seeking to see it banned from my state. I encourage folks to do the same.
