American Bully Breed Standard Update

Effective January 1, 2024

November 30, 2023


Effective January 1, 2024
The American Bully breed standard has been updated to include the common sizes/styles of the breed, among other edits. While the American Bully will not be exhibited as separate varieties, it is important to note the distinct style types found within the American Bully breed. Those styles are: Pocket, Standard/Classic, XL. Additional revisions include edited descriptions of the breed to align more closely with the look of an ideal specimen.

The American Bully breed was initially recognized in 2013. Ten years later, the dogs being produced by our dedicated and knowledgeable breeders display unmistakable quality, soundness, and type, which the standard has been updated to acknowledge. Throughout 2023, we accepted feedback from multiple Bully breeders and judges. The updated standard is effective January 1, 2024.

United Kennel Club wholeheartedly supports the American Bully. We do not shy away from the unique and distinct breed it is. The American Bully is a beefy, balanced dog, and exhibits 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, and they have a firm "off" switch for when it's time to lounge and relax with family. The American Bully breed moves with a jaunty, confident attitude, conveying the impression that he expects any minute to see something new and exciting.

Notable revisions:

  • While it originated as a natural extension of the APBT, the American Bully is not a Terrier. Note the addition of these serious faults: Leggy, terrier-like structure, lacking muscle.
  • Acknowledgement of distinct styles: Pocket, Standard/Classic, XL. The Classic has a lighter body frame and less overall body mass than the Standard while still exhibiting Bully traits and measuring the same at the withers.
