Totally different type of dog. They are big and strong and I would say that they require a handler of the same. I have met quite a few (upwards of 10-20) and only maybe 2 have had decent temperaments..They seem to be the new breed of choice for the people who used to use Pit Bulls as their breed of choice for the "macho man" appearance.
