Quoted from the American Bully Kennel Club, here are some general yet important characteristics that American Bullies must offer. You can find the full American Bully standard on the ABKC’s website.

The American Bully should give the impression of great strength for its size. It is a compact to medium/large size dog with a muscular body and blocky head, powerful in its movement and should display effortless movement at the same time. It is keenly alive and alert to its surroundings. The American Bully should have the appearance of heavy bone structure with a Bully build and look.
The American Bully is a companion breed exhibiting confidence, a zest for life, along with an exuberant will to please and companionship with their family. This making the American Bully an excellent family companion. Despite the American Bully’s fierce and powerful appearance their demeanor is gentle. They are great with kids, and extremely friendly with strangers, other dogs, and other animals. Human or dog aggression, extreme shyness, or viciousness is very uncharacteristic of the American Bully and is highly undesirable. It is important to note that all colours and patterns are accepted though the coat must be
close and short. There is no particular weight for the breed but there are height and weight ratio restrictions for the bully’s varieties defined in the following section.
With a great standard now in place, and different types clearly defined, the future of the breed lies in the community following the guidelines and evening out all the specimens out there labelled as American Bullies.
Once most of the breed’s specimens, whether officially registered or not, look similar and are clearly identified, it would mean that the breed as matured and can be taken more seriously by bigger organisations such as The American Kennel Club.
This is why many influential figures of the bully community push conformation shows so the breed sticks to its standard and non-confirm specimens get discarded of their breeding programmes.
As soon as The American Kennel Club shows full recognition of the American Bully, it will send a strong signal internationally and develop the breed even more, especially in South Africa where the breed is already hype, and other English-speaking countries.
