mostly APBT's, have shown that those trained to pull for their owners satisfaction (gameness)
Nick, where did you get your info from. Where did you get this definition of gameness. I think you may need to do some more research on your dogs. Gameness cannot be taught, if that was the case any dog could be a catchdog. My definition of gameness -- willingness to continue despite taking punishment. Don't confuse gameness with aggression. An aggressive dog is not necessarily a game dog. People who don't understand this take aggressive dogs, breed them and make more aggressive dogs. In the 1970s a pit bull attack was unheard of. The men who had the dogs knew what to look and breed for. It wasn't until the dogs ended up in the hands of ignorant thugs that pit bull attacks started taking place. BAD BREEDING. Not knowing the difference between gameness and aggression. In my opinion, the APBT has the most stable temperament of any dog. I raised gamedogs for years and never had a dog just turn and attack. They are what they are, if I had a dog that acted funny towards people I knew it from the first day I had them. The stories of these dogs (most of the time) turning and just attacking is BS. The dog was human aggressive the whole time and I guarantee the owner knew it. The phrase "turn on" is a whole different story than what it has been recognized as. Nick, I don't expect you to understand everything I'm saying, people with gamedogs know exactly what I mean. I'm sorry, I started rambling on. Nick, my advice is to search and study up on the gamedog, maybe even own a few then form your own opinion. Don't believe everything the media tells you.
My source of information came from a random book I come across at the pet store, "Training Secrets for Bully Breeds." The book is comprised of several articles written by professional trainers and some dog behaviorists. Dr. Ian Dunbar, a world reknown trainer/animal behaviorist, was contacted for some articles since he loves the bully breeds.
They state that although "game" originated as a fighting term, it refers to a dog's tendency to continue in the face of adversity. What I was refering to in my previous post was that these breeds thrive off of their masters satisfaction and will continue to try as hard as they can for as long as they can. They then go on to talk about weight pulling competitions and dog fighting, stating that owners will position themselves in such a way that the dog can always see them rooting for them.
Like I said before, I am no expert by any means. I just like to read and this information is what the experts have to say about the subject.
