no, pitbulls were BREED to fight, due to its physiology, and its brute strength pound for pound also its jaw's vice-like strength, also come to think of it, during WW2, GSD were the 'only ones around' pitbulls wasnt breed or developed yet, (could be wrong someone could google that im half piss in gonna bed now so i cant be bothered) but for now i saying the police , armed forces used GSD for i thnk 2 reasons, they were already know, and size is another thing, bigger to look more scary ofc...
the games changed...now we have vicious strands of the breed and stupid people using them to boost own egos....
and sadly , those dogs are forced to do against their will, but only get stuck in fighting mode because they had to survive, not nice at all for everyone, includig the dog, the dog's lost their rights to live, simply because they trained to go 'feral; for some wanker's kicks...
