Where were you when you heard your first bully breed urban legend? We've all come across at least one: A story about a bully that "just snapped" and attacked a person or another dog without warning. 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.

But according to groups like the ASPCA and Pit Bull Rescue Central (PBRC), bully breeds -- including the American pit bull terrier, the bullmastiff and the American Staffordshire terrier, among other breeds -- can make for great family pets when they're properly trained and socialized. And there's plenty of research to back that up. So before you buy into the scary stereotypes, read on to learn the truth behind five common bully breed myths.
