The American Staffordshire Terrier, often affectionately called “AmStaff,” is a breed developed in the United States from its British cousin, the Staffordshire Bull Terrier. Bred originally for farm work, companionship, and guarding, the AmStaff is now known as a devoted family dog with a strong sense of loyalty and an energetic spirit.

This breed is muscular and compact, with a broad head, powerful jaw, and expressive eyes. Despite their tough appearance, AmStaffs are affectionate, playful, and love being around people. With proper training and socialization, they’re gentle with children and loyal to their households.

They are intelligent and eager to please, but also energetic and strong-willed — making consistent training and early socialization essential. The AmStaff thrives in active homes where they’re given structure, stimulation, and affection.
