If there someones rabbit dogs they should have a collar on with a name plate and phone number. Someone may be turning the dogs in there and hunting on your place. If you can catch one of the dogs you can get the info. off the collar the local wildlife officer can have a talk with them. If they don't have a collar on then they are not hunting dogs or there deer dogs someone doesn't want to get caught with. If there strays or someones illegal deer dogs put a bullet to them and don't worry about it.
