Pitbull Locking Jaws - Myth or Truth

Often, these stories come complete with colorful descriptions of bully breeds' supernatural strength, locking jaws, or inability to feel pain. Many times, the tale has come to you by way of a "friend of a friend" or a "friend's neighbor who saw it happen to someone a while back." Almost always, the dog at fault is described as a "pit bull," with no additional details as to its specific breed or background.
These may seem like innocent rumors to pass around, but over the years, they've led many people to avoid adopting bully breeds. In some cases, those myths and assumptions about the dogs' supposedly aggressive natures have even led to regional bans on bully breed ownership.
