I had a buddy who had one and that thing could stop a truck and would hunt 'til it couldn't. He had kids and never really established himself(or his family) as the "alpha" to that dog and it got to the point he had to get rid of it. Like any dog, if you put your time into it, it'll pan out. Pound for pound, there's not a stronger dog out there that I've ever seen....and they swim better than a fish.
