American Bully XL: The Complete Guide to the Breed's Biggest Size Class
The American Bully XL is the largest size class of the American Bully, with males standing over 20 to 23 inches at the withers and females 19 to 22 inches, typically weighing 80 to 150 pounds. Despite its powerful, muscular build, the XL Bully was bred as a companion dog and is generally affectionate, loyal, and gentle with family. It needs moderate exercise, firm early training, and an owner prepared for a large, strong breed.
What Is an American Bully XL?
The American Bully XL is not a separate breed but the tallest of the four size classes recognized by the American Bully Kennel Club (ABKC): Standard, Pocket, XL, and Classic. According to the ABKC, the only criterion separating these classes is height — the XL simply describes a taller, heavier dog with the same breed characteristics as the Standard.
The American Bully itself is a relatively modern breed, developed in the United States during the 1980s and 1990s and recognized by the ABKC in 2004. Its foundation traces to the American Pit Bull Terrier and the American Staffordshire Terrier, with some bloodlines incorporating bulldog-type breeds. Like other purpose-bred modern breeds, it was developed for a specific goal: a muscular, blocky appearance paired with a stable, people-friendly temperament.
American Bully XL Size and Weight
Size is what defines this class. Under ABKC standards, adult XL males measure over 20 inches up to 23 inches at the withers, and females measure over 19 inches up to 22 inches. Weight commonly falls between 80 and 150 pounds for males and 70 to 120 pounds for females, though individual dogs vary based on bloodline and build.
XL Bullies are slower to mature than smaller breeds. Puppies can gain a few pounds per week during peak growth, and most do not reach their final size until around 18 to 24 months of age.

Appearance and Coat
The American Bully XL has a heavily muscled, compact body, a broad chest, a large blocky head, and a short, glossy coat that lies close to the skin. Coat colors are wide-ranging and include black, blue, fawn, brindle, white, chocolate, and tricolor patterns. Grooming needs are minimal — the short coat requires only weekly brushing and occasional baths, and shedding is light to moderate.
Temperament and Personality
Despite an intimidating appearance, a well-bred American Bully XL is known for a gentle, affectionate temperament. The breed was developed specifically as a family companion, and reputable breeders prioritize stable, confident, human-friendly dogs. Most XL Bullies are loyal, eager to please, and notably patient with children — traits that have made them popular family dogs.
Temperament always depends on breeding and upbringing, however. With a dog this size and strength, early socialization, consistent boundaries, and responsible ownership are non-negotiable. A properly raised XL Bully is a calm, devoted companion; a poorly bred or under-socialized one is a large dog that is difficult to manage.
Exercise and Training Needs
XL Bullies have moderate energy for their size. Plan on 45 to 60 minutes of daily exercise — brisk walks, structured play, and light strength activities all work well, but avoid overexerting puppies whose joints are still developing. Because the breed is muscular and heavy, low-impact activity protects growing bones.
Training should start early and lean on positive reinforcement. These dogs are intelligent and eager to please, which makes them highly trainable, but their size means leash manners, recall, and impulse control are essential from puppyhood. Owners of other powerful mixes like the American Pit Corso or Bullboxer Pit will recognize the same need for firm, consistent guidance.
Health and Lifespan
The American Bully XL typically lives 10 to 12 years. Because of their bulky build, XL Bullies can be prone to hip and elbow dysplasia, heart conditions, skin allergies, and — in dogs bred to extreme proportions — breathing and mobility problems. Choosing a breeder who prioritizes health and function over exaggerated size is the single most important step toward a sound dog.
This is general information, not veterinary advice. Keep your XL Bully at a healthy weight, provide joint-supportive nutrition, and consult your veterinarian for screening recommendations and any health concerns.
Ownership, Cost, and Legal Considerations
XL Bullies are among the more expensive dogs to buy, with prices commonly ranging from $2,000 to $10,000 or more depending on bloodline and breeder reputation. Prospective owners should also research local laws: the breed has drawn regulatory attention in some regions, and certain jurisdictions — notably the United Kingdom — have introduced restrictions specifically targeting XL Bully-type dogs. Always verify breed-specific legislation and housing or insurance rules in your area before bringing one home.
