Previous next-door-neighbours' lad was a wannabe gangsta and bought a "pitbull" (before the XL bully really landed here.) Called it Tyson, predictably.
Unfortunately for him and luckily for me, he was literally "sold a pup" and it grew into an English bull terrier. Didn't have the square jaw of a pitbull. Once it grew out of the nippy, chewy puppy phase it was as soft as anything; lovely dog. To be fair to the lad, he did train it properly.
The only time I've been bitten myself was by a typical "small pet" dog. I was a small child. It didn't kill me. The outcome would most likely have been very different if it were an XL bully. The owner (a relative) had it PTS immediately.
