Two varieties, one breed -- a judge's guide to the structural distinctions that define each class
The American Bully is a young breed, but its evolution has been remarkably deliberate. When the American Bully Kennel Club established its four recognized varieties -- Standard, Classic, Pocket, and XL -- the goal was not simply to sort dogs by size. Each variety was designed to honor a distinct expression of breed type. Nowhere is that distinction more nuanced, more frequently misunderstood, and more important to the breed's future than in the relationship between the Classic and the Standard.
Walk a line of American Bullies at any ABKC-sanctioned show and you will see it immediately: the Standard is an unmistakable powerhouse, thick through the chest and shoulders, heavy-boned, projecting mass and presence from across the ring. Standing beside it, the Classic shares the same height range but reads entirely differently -- cleaner lines, a more athletic silhouette, a build that whispers of the breed's American Staffordshire Terrier and American Pit Bull Terrier roots.
The difference is not about height. It is about architecture.
“The Classic is not a Standard that missed the gym. It is a deliberate expression of breed type that honors where this breed came from.”
The head is the hallmark of the American Bully. The ABKC standard calls for a "distinct heavy, large and broad head" that is "medium in length, deep throughout, broad skull, well chiseled with very pronounced cheek muscles, distinct and deep stop." Both varieties must meet this standard, but the way that standard manifests differs in practice.
In the Standard variety, judges expect to see maximum expression of head type: a wider skull, heavier muzzle, more pronounced cheek musculature, and an overall blockier appearance. The head should convey power and substance immediately. The stop is deep and dramatic. The jaw is broad and imposing.
The Classic head, while still undeniably an American Bully head, presents with slightly less exaggeration. The cheek muscles are defined but not as dramatically pronounced. The muzzle may appear marginally more refined. The overall impression is of a head that balances strength with clean lines -- reminiscent of the American Staffordshire Terrier and classic American Pit Bull Terrier heads that sit at the foundation of the breed's lineage.
"I look for a head that belongs on that body," explains judge Denise Okafor. "On a Classic, a head that is overly bulky and exaggerated would look out of proportion with the lighter frame. On a Standard, a narrow or refined head would be just as wrong. The head has to match the architecture of the dog."
This is where the two varieties truly diverge. The Standard American Bully is built to project mass. The standard calls for a "heavily muscled, massive bulky body type of compact/medium length giving the impression of great power for its size." Ribs are well-rounded, creating a barrel chest. The chest is broad, deep, and well-filled. Forelegs are set wide apart to accommodate chest development. The overall silhouette is thick, compact, and imposing.
The Classic retains the breed's essential structure -- correct topline, proper angulation, well-sprung ribs -- but with a lighter frame. Where the Standard is thick, the Classic is athletic. Where the Standard projects mass and density, the Classic projects agility and proportion. The Classic should appear capable of sustained physical activity; its musculature is lean and defined rather than bulging and heavy.
This distinction extends to bone. Standard Bullies exhibit heavy, round bone that supports their substantial mass. Classic Bullies carry lighter bone that is proportionate to their leaner frame. Neither is superior; each is correct for its variety.
“On a Classic, a head that is overly bulky and exaggerated would look out of proportion with the lighter frame. The head has to match the architecture of the dog.”
Gait is where structural integrity reveals itself, and it is where the differences between Classic and Standard become kinetic. Both varieties should move with confidence, power, and efficiency. The ABKC standard calls for movement that is "effortless and powerful," with dogs keenly alive and alert to their surroundings.
In practice, the Standard's heavier build produces a gait that is rolling, ground-covering, and powerful. There is a deliberate quality to the Standard's movement that reflects its mass. The Classic, with its lighter frame and leaner muscle, tends toward a freer, more fluid gait. Its reach and drive may appear more pronounced simply because there is less mass to carry.
"If a Standard moves like it is pulling a plow, something is wrong," says Judge Ellison. "And if a Classic moves like it is wading through mud, something is wrong. Both should be balanced, efficient, and sound. The difference is that correct Classic movement will have a bit more freedom and flow."
When evaluating Classic entries, ABKC judges are assessing breed type within the context of the variety. The Classic must exhibit recognizable American Bully characteristics -- the broad head, the confident temperament, the compact body -- while simultaneously presenting the lighter, more athletic build that defines its class.
Common judging errors include penalizing Classics for lacking the substance of a Standard, or rewarding Standards that are simply overweight and unfit. Substance is not fat. Athleticism is not underweight. Each variety has its own ideal, and judges must evaluate each dog against the standard for its class.

“If we lose the Classic, we lose our roots. Every breed needs genetic breadth. The Classic gives breeders a path to maintain structural soundness and breed diversity.”
The Classic variety is not a relic or a compromise. It is a living bridge to the breed's heritage and a vital contributor to genetic diversity. The American Bully was developed from the American Pit Bull Terrier and the American Staffordshire Terrier, with additional influence from the American Bulldog and English Bulldog. The Classic preserves the athleticism and functional structure of those foundation breeds while still exhibiting the temperament, head type, and presence that define the American Bully.
"If we lose the Classic, we lose our roots," says breeder and judge Patricia Navarro. "Every breed needs genetic breadth. The Classic gives breeders a path to maintain structural soundness, functional movement, and breed diversity. That is not a weakness. That is forward thinking."
As the American Bully community continues to grow, understanding the distinction between Classic and Standard is not just an academic exercise. It is essential knowledge for breeders making pairing decisions, for handlers presenting dogs in the ring, and for judges whose placements shape the breed's future. The Classic and the Standard are two expressions of one breed -- each with its own ideal, each deserving of respect and precise evaluation.
They share a height range. They do not share a body type. And that is exactly as it should be.
