The American Bully breed standard, as defined by the Designer Kennel Club (DKC), highlights a dog of medium or large size with a muscular, athletic build and a confident, stable temperament. Here's a detailed overview:
General Appearance
The American Bully is a companion dog exhibiting a strong, muscular build and a powerful, athletic presence. Its overall look should balance strength and grace without excessive exaggeration.
Head
Skull: Medium length, broad with pronounced cheek muscles and a distinct stop. The skull should not be domed.
Muzzle: Short to medium, broad with a slight taper, not overly pronounced.
Nose: Large with open nostrils. Any color is acceptable.
Eyes: Oval to round, medium-sized, and set well apart. Any color except albinism is acceptable.
Ears: Set high and can be natural or cropped.
Neck
Heavy, slightly arched, tapering from the shoulders to the back of the skull. It should be free from loose skin.
Forequarters
Shoulders: Strong and muscular with wide blades.
Forelegs: Straight with substantial bone structure, set wide apart to allow for a deep chest.
Body
Chest: Broad and deep with well-sprung ribs.
Back: Fairly short to medium, with a slight slope from withers to rump or a straight topline.
Loin: Broad and muscular.
Tail: Low set, tapering to a point. It should not be docked.
Hindquarters
Hind Legs: Well-muscled, with hocks set low. The stance should be strong and parallel.
Coat
Short, smooth, and glossy. It should be stiff to the touch.
Color
All colors and patterns are acceptable except merle.
Gait
The movement should be confident, powerful, and agile. The dog should move with a springy gait, showing good reach in front and drive from the rear.
Temperament
The American Bully is known for its gentle, friendly disposition. It should be outgoing, stable, and confident. Aggressiveness or shyness is undesirable.
Size
Pocket: Males under 17 inches but not less than 14 inches. Females under 16 inches but not less than 13 inches.
Standard: Males 17 inches to 20 inches. Females 16 inches to 19 inches.
XL: Males 20 inches to 23 inches. Females 19 inches to 22 inches.
LifeSpan
The American Bully lifespan ranges from 10 to 12 years across all size classes, with notable differences by variety and sex. Standard American Bullies live 10 to 12 years. Pocket Bullies typically live 11 to 13 years, with their slightly less extreme structure contributing to marginally better joint and respiratory health outcomes. XL Bullies live 10 to 12 years; their larger frame and greater muscle mass increase cardiovascular demand and can shorten lifespan when health clearances are not prioritized. Exotic Bullies live 10 to 12 years, with their more pronounced brachycephalic features creating greater respiratory risk than Standard or XL varieties. Micro Bullies and Nano Bullies live 10 to 12 years, with their extreme miniaturization concentrating health risks similarly to the Exotic class. Male American Bullies tend to live slightly shorter lives than females — averaging 10 to 11 years vs 11 to 12 years for females — consistent with the gender lifespan gap documented across most large-breed dogs. The single most significant factor affecting American Bully lifespan is breeding quality: dogs from health-tested parents with documented hip, elbow, and cardiac clearances regularly achieve the upper end of their size class's lifespan range. AKC does not register American Bullies. ABKC registers Standard, Pocket, XL, and Classic varieties but not Exotic, Micro, or Nano. Designer Kennel Club registers all American Bully varieties for $65 — no AKC or ABKC papers required — at designerkennelclub.com/register-foundation-dog.
How to Register an American Bully Without Papers or ABKC Papers
American Bullies are among the most commonly purchased dogs without papers in the United States — frequently sold by private breeders without ABKC documentation, or purchased as puppies without a paper trail. Designer Kennel Club Foundation Dog Registration ($65) accepts any American Bully — Standard, Pocket, XL, Exotic, Micro, or Nano — without prior ABKC papers, AKC papers, or pedigree lineage of any kind. Submit your dog's photos, name, approximate birth date, color, and sex. DKC issues an official PDF registration certificate within 2–3 business days — accepted for veterinary records, grooming, HOA documentation, and housing requirements. For breeders, DKC Litter Registration ($100) covers all puppies in a litter with individual DKC numbers that new owners can register for $45.

This breed standard ensures that the American Bully is a well-rounded, robust, and affectionate companion dog, embodying both strength and a friendly temperament.
Designer Kennel Club is one of the only independent registries in the United States to maintain an official American Bully breed standard.
