Revised and Expanded Standard
History
The American Bully originated in Los Angeles California in the late 1980s and early 1990s as breeders sought to create a companion dog with the physical stature of the American Pit Bull Terrier but a more muscular build and a temperament better suited for family life. The foundation of the breed includes influences from the American Pit Bull Terrier, American Staffordshire Terrier, and various Bulldog breeds, selectively bred to enhance specific traits such as bone density, head size, muscle mass, and overall stability.
While retaining the tenacity, intelligence, and confidence of its ancestors, the American Bully is distinct in both appearance and temperament. Over the past few decades, the breed has evolved significantly and is now recognized globally, celebrated for its balanced power, compact frame, and loyal nature.
General Appearance
The American Bully should present a strong, confident, and muscular appearance with a blocky, proportionately large head, broad shoulders, and a compact frame. The breed embodies power without exaggeration and should never appear excessively overdone or hindered in mobility.
The American Bully exudes a natural presence of strength and determination, combined with a poised, stable, and friendly demeanor. Both males and females must display balanced proportions, with females being slightly less muscular and more refined.
Size Variants
The American Bully is classified into size variants. All types are judged by the same standard, with height being the only differentiating factor. Dogs must remain within healthy proportion.
