The American Pitbull Terrier and American Staffordshire Terrier originated in the United States. The dog breed "pitbull" that seems so popular with identifying mixed breeds that look like this picture, does not exist.
If you’re lucky enough to share your life with a Pit Bull, or a dog who falls under the bully breed category, you know it takes a special kind of person to take on the challenge of loving a breed that has such an undeserved bad rep.
I am a firm believer in it being the owners fault for how pits are looked at! A small dog could be aggressive as well just depends how they grown up. I know many people with pits that are great family dogs!
