HISTORY

The American Bully breed developed as a natural extension of the American Pit Bull Terrier. The APBT has maintained a characteristic appearance and temperament for over 100 years. As with any long-standing breed, several types evolved from the parent breed, with one in particular taking on a specific build and structure that is so unique it was wise to recognize it as a different breed altogether. That being the American Bully breed.
The American Bully breed was subtly influenced by the infusion of several other breeds, which include the American Pit Bull Terrier, American Bulldog, English Bulldog, and Olde English Bulldogge. While these breeds were utilized in the creation of the American Bully, it is a breed of its own and should not specifically resemble any one in particular.
The American Bully breed was recognized by the United Kennel Club on July 15, 2013.

GENERAL APPEARANCE

The American Bully is found in three distinct sizes, the Pocket, Standard/Classic, and XL. The Classic has a lighter body frame and less overall body mass than the Standard while still exhibiting bully traits. The breed is recognizable by its characteristic compact, strong, thick-set structure and build. Their appearance reflects a strong American Pit Bull Terrier foundation, blended with stock from other bull breeds.
The overall balance and correct proportions are essential, and absolute soundness and proper muscle tone is a must.
It is a smooth coated dog that possesses great strength for its size. Although quite muscular, it is active and agile. Its presence is a picture of tremendous power and stamina that belies its kind and loyal temperament.
Eliminating Faults: Any disproportionate, overdone characteristic that would interfere with physical activity.
Disqualifications: Unilateral or bilateral cryptorchid.

CHARACTERISTICS

The American Bully breed is, first and foremost, a companion, exhibiting confidence with a zest and exuberance for life. Despite its powerful appearance, their demeanor is gentle and friendly. This breed makes an excellent family dog. The ideal American Bully possesses the athleticism to do well in performance events.
Aggressive behavior towards humans is uncharacteristic of the breed, and highly undesirable.

The head appears square from the front and side without any wedge appearance.

The docking of tails and cropping of ears in America is legal and remains a personal choice. However, as an international registry, the United Kennel Club, Inc. is aware that the practices of cropping and docking have been forbidden in some countries. In light of these developments, the United Kennel Club, Inc. feels that no dog in any UKC event, including conformation, shall be penalized for a full tail or natural ears.
