They’re not wild - they’re OVER bred, if anything.
As in way too many of them. One pit bull left in the world should be sufficient to cure the overbreeding problem.
They are probably not bred well by responsible breeders. I think a lot of backyard breeding goes on with pit bulls. A responsible breeder would not breed for agression in a dog. I think this breed is bred for the most part by yahoos who just want a vicious dog.
When I walk my little corgi, I am always armed in case a pit bull should attack him (or me).
