We got our dog from pound, mixed breed which I think is best and most healthy, smartest of dogs, smallest of big dogs, has border collie in him, so does hand signals without training, never barks at strangers, but know he would attack if I was threatened. He came fine, but he and my husband both got Lyme Disease in our woods. Both treated, husband fine, but Ossie (dog) gets weird leg things, that looks very neurological. Happens on occasion, still a great dog. If you can't train animal, go to a class or get a trainer. No one really likes a wild child, we owe it to our pets also to make them as acceptable to others. Os is Border collie, German Shepard and maybe a little Rottweiler. Nice mix. Ossre was 7 months, already trained, wonderful dog. All DS' friends want him. He never jumps on you.
