A professional veterinarian can only correctly identify a pitbull visually about 75% of the time.🙂🙃
If you show a vet 100 dogs, where only 21 of those dogs are pitbulls, the vet will identify about 52 of those dogs as pitbulls. Without DNA tests, everyone massively overcounts pitbulls.

So when people say pitbulls are the most dangerous and rottweilers are number 2, they are wrong. Because pitbull is effectively a catch-all term for "scary looking dog"
