I have the same problem with one of my areas, but they can't shoot onto it. The area above me has my hunting property on one side and other private land on the other side of the road. They can't shoot from the road onto any property and they know this, but they still drop their dogs off on the other side of the leased land so they can run toward this road. I caught one shooting and let him know next time he'll be prosecuted. They solved that problem by trying to release the dogs ONTO the property I hunt so they can push deer out to where they CAN shoot. Caught them doing that this weekend. They've even run off the two small does I've been trying to get.

It's a never ending battle, if you stop them from doing one thing they're going to do another.
