Summary
About American Staffordshire Terrier
American Staffordshire Terrier: muscular, medium-sized, people-focused dog with a short, easy-care coat in many colors. Affectionate, energetic, and highly trainable with consistent, positive handling. Needs daily exercise, mental stimulation, socialization, and responsible management.

Large, powerful livestock guardian, calm and observant yet strongly protective. Quiet and laid back at home if well exercised, deeply loyal with family and usually reserved with strangers. Independent and thoughtful, it suits experienced owners with space, structure and early socialisation.
