Forget what they look like -
Pits and variants are different because 1) they snap in a second for no logical reason and 2) you can’t read ‘em like you can almost every other dog (excepting SharPeis and other mental specialty retards) and 3) they can and will KILL when they snap.
Not all, but MANY are a TREMENDOUS danger to kids.
I advise terminating the breed, neighborhood by neighborhood, using whatever means necessary.
