Two dogs tend to wander all over where as one won't. Call around within a mile or so and find out whose they are. We had a beagle get loose and our normally home-bound sheltie ran off with it all over the place, as far as a mile away we got calls! If they are wild they should be destroyed as they can only cause a lot of harm and/or spread rabies. And NO dogs have the right to wander all over the place in most, if not all, states - where we are, you can get a few hundred dollar fine if your dog is wandering all over causing problems.
