Gamebred - Bred for gameness. Gameness - Dog fights/works till it is physically exhausted. Are pits gamebred for herding sheep?
EDIT - Yeah, I suppose you could unlock recessives breeding for temperament/breed standard, and a certain low% would be game, but IME, the dogs pups are pretty predictable if you know the parents. If you breed 2 dogs on the basis of 'great dog, he is tolerant and submissive, AND meets the breed standard to a female with the same qualities, 95% of the pups will fall somewhere between the parents in ALL aspects.
