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.
Look at that Happy face! All pitties want is someone to love. Blame the deed not the breed! They are the most affectionate dogs. Think about giving a homeless dog the happiness that is written all over this puppy's face.
