Pit Bull's are A breed. As far as actual pit bulls go they are registered with AKC as American Staffordshire Terriers and UKC as American Pit Bull Terriers but most are actually dual as it's the same history and they meet standard for both so are shown with both. There are also many mix breeds that are promoted as 'pit bulls' so if you don't have those registration papers from either one, is just as likely to be a mix or even a different breed sometimes.
