Yeah, they were bred to kill other dogs, not people. And no pit bull is that big at six months, or any other time in its life. Sounds to me like someone sold these idiots a "fad" dog, or a bluff dog, calling it a pit bull, and the owners bought it because they didn't bother to learn about the breed standard. Perhaps that is why so many of these man biters are HUGE. They're overpriced, badly bred mutts with the pit bull name. It's a shame because dogs like mine (43 pounds and extremely human friendly, just as the standard states)are getting a bad name because of these dopes and their thousand dollar "rare" pits.
The reason so many children are attacked by pit bulls is that the dogs do not recognize that something that is small and down on their level is human.
