The problem is that pit-bull terriers are actually a type of terrier, not a breed, per se. Just as there are greyhound types (not capitalized), and retriever types, and spitz types.
Even using “type” as opposed to “specific breed” - PBT loses, I’m afraid.
Of course, there’s also the problem that many morons can’t tell a Labrador from a PBT, anyway, much less any mutt. There are many more mutts out in the world than any lists would imply. So we can’t always count on the ID being correct. (Which is why I totally oppose “breed” legislation.)
What Pit Bull? You mean this dog? Yeah, her name's Killer and that's why she's on this leash . . . !!!????!!!
Vets don't always ID breed mixes correctly, let alone Animal Control (notoriously inaccurate) or the newspaper reporter who probably never saw the dog, but thinks that "Pit Bull" sells papers. I'm totally opposed to breed legislation too, given the mouth breathing morons who would be "identifying" the breed.
