I have seen some yippy dogs that might qualify for insane. I think their unnaturally small size and perhaps poor upbringing my have caused them to have a loose screw or two. I had a neighbor with a Rottweiller, incredibly friendly dog. He might lean on you to death waiting for you to pet him. I think the general rule is "bad dog, bad owner".Raised and owned several pitties as a child, some of my favorite dogs. Absolute sweethearts.
Edit: If there are "insane" breeds (and I may regret asking this), but what human breeds are insane, Asian, Black, White, Hispanic?
