One of the most unique and often misunderstood aspects of the American Bully breed is its size classification system. Unlike many dog breeds that have a single height range, the American Bully is divided into five recognized size classes, all following the same breed standard but differing in height and proportion.
Understanding the American Bully size classes is essential for:
- Choosing the right Bully for your lifestyle
- Setting realistic expectations for growth and care
- Avoiding misinformation and marketing hype
This guide explains each American Bully size class, how they differ, and what truly matters beyond size alone.
Why Does the American Bully Have Size Classes?
The American Bully was developed as a companion-focused breed, not a performance or working dog. As the breed evolved, breeders produced dogs of different heights while maintaining the same core traits:
- Muscular build
- Broad chest
- Blocky head
- Stable temperament
To maintain fairness in shows and clarity for owners, registries such as the American Bully Kennel Club (ABKC) established height-based size classes, not separate breeds.
All American Bullies — regardless of size — should display:
- Balance and proportion
- Sound movement
- Correct structure
- Confident, people-oriented temperament
Overview of the Five American Bully Size Classes
The five commonly recognized size classes are:
- Micro American Bully
- Pocket American Bully
- Standard American Bully
- Classic American Bully
- XL American Bully
Each class appeals to different owners, but size alone does not determine quality.
1. Micro American Bully
The Micro American Bully is the smallest and most compact type. While not officially recognized by every registry, Micros are widely accepted within the Bully community and have become increasingly popular.
Typical Characteristics
- Extremely short height
- Very compact frame
- Heavy bone relative to size
- Wide chest and thick muscle
Micros are prized for their dense structure and presence in a small package. However, responsible breeding is especially important to ensure sound joints, mobility, and overall health.

Pocket Bullies offer the muscular look the breed is known for while remaining manageable in size for many households.

The Classic American Bully shares the same height range as the Standard class but has lighter bone and muscle mass.
Key Traits

- More traditional bulldog influence
- Less exaggerated muscle

Classic Bullies appeal to owners who prefer a more old-school look while retaining the Bully temperament.

Despite their size, well-bred XL Bullies should still be stable, friendly, and people-oriented.
Temperament Across Size Classes
One of the most important things to understand is that temperament does NOT change significantly by size class.
Across all classes, the American Bully should be:
- Loyal
- Confident
- Social
- Calm around people
Differences in behavior usually come down to:
- Breeding quality
