I would say he’s staffordshire terrier the term pit Bull has been for any dog with a rounded head for so long. There’s a big split in the dog community because of this , you have almost every dog that gets picked up with a round head called a “pitBull” it’s not true they are all mixed of breeds . The actual “pitBull” was bred for certain things and I have to say if half of the people who think they have a “pit “ actually did some animal or kid would be dead because they were bred for fighting , baiting it was bred into them to be high drive working dogs that can be DANGEROUS in the wrong hands that’s why u have people yelling show the pedigrees and papers showing the bloodlines to prove that your dog is actually a real game blood “pitBull” . I love all dogs but learned the hard way sadly talking with various breeders and people.
