Wow, yet another mere coincidence
There are characteristics that pit bulls display when they attack that differ from all other dog breeds. One of these characteristics was their lethal bite. They’re the only breed that grabs & shakes without opening the jaw, which is why owners are advised to carry a break stick to facilitate the release of its grip on another dog. The Colorado Supreme Court even cited these differences when they upheld the Denver pit bull ban in 2005:
“[pit bulls] inflict more serious wounds than other breeds. They tend to attack the deep muscles, to hold on, to shake, and to cause ripping of tissues. Pit bull attacks were compared to shark attacks.”11
