DNA test or it wasn't a Pit Bull. I do strongly agree, though, that size and capacity for harm matter. Before the 2000s moral panic around "Pit Bulls", the #1 breed reported in dog attacks was the Labrador. Labs are big enough to cause serious harm, and bred for prey drive. Popular and photogenic, though, so the moral panic fizzled quickly. Before that, German Shepherds were the moral panic breed of the 1980s - but since fashion among bad people moved on long ago, the breed's reputation has improved.
