You are right about Red Bellies Morgan but although they might try to avoid trouble, sometimes they have no choice, being in the wrong place at the wrong time. In the mid-1980s we had an unraced Wild Port dog who dived into the grass coming out with a Red Belly wrapped around him. The dog was muzzled. With the benefit of a big vet bill he was saved and thankfully he was a very good dog from the financial viewpoint.
