The American Bully is a relatively new breed, developed in the United States during the 1980s and 1990s. The goal wasn’t just to create a powerful-looking dog—it was to build the ultimate companion: strong, muscular, but calm, friendly, and family-oriented.

🔥 The Foundation
The breed started with two key players:
American Pit Bull Terrier Brought athleticism, drive, and that signature muscular build.
American Staffordshire Terrier Added a broader frame, a more defined head, and a stable, people-friendly temperament.
👉 These two breeds form the core DNA of the American Bully.
🧬 Additional Influences
To fine-tune the look, breeders introduced other breeds into certain lines:
English Bulldog Helped create a thicker body, wider chest, and more compact structure.
Olde English Bulldogge Added density, strength, and exaggerated muscle.
French Bulldog (in some lines) Influenced smaller sizes and certain compact features.

Raising a Strong Bully Puppy: Why Growth Plates Matter
There is nothing more exciting than bringing your new Bully puppy home. Whether you’ve chosen an American Bully in Standard Bully class, Pocket Bully, Micro Bully, Exotic Bully, those first weeks are full of energy, personality, and nonstop movement — followed by long, deep puppy naps.
Because they seem so active, many owners assume puppies can’t get “too much” exercise. Some even believe it’s fine to let them run and play until they completely tire themselves out.
But during early development, that approach can quietly cause long-term damage.
At 8–10 Weeks: They’re Still Under Construction
When you bring home an 8–10 week old Bully puppy, remember this:
Their bones are not fully formed. Their joints are not fully structured. Their growth plates have not closed.
Those oversized paws and wobbly movements aren’t just cute — they’re signs of an immature skeletal system. At this stage, joints are supported primarily by muscle, tendons, and ligaments, with soft cartilage areas at the ends of long bones. The bones are not yet tightly fitted into strong, stable sockets.
Your puppy is literally building its frame.
What Are Growth Plates?
Growth plates (also called epiphyseal plates) are soft areas of cartilage located at the ends of long bones. As your puppy matures, these plates slowly harden (calcify) and turn into solid bone.
For healthy development, bones must grow evenly and at the same rate. This synchronized growth is critical for producing correct structure, balance, and movement — especially in powerful, muscular Bully breeds.
Until the growth plates fully close, they remain vulnerable to injury. They are actually the last part of the bone to harden.
If a growth plate is damaged:
Growth on that side may slow or stop.
The opposite side may continue growing normally.
This uneven development can cause deformities and lifelong structural problems.
One of the most common areas for growth plate issues is between the radius and ulna in the front leg. If one bone stops growing and the other continues, it can result in bowed legs and an abnormal gait that affects the dog permanently. Over time, this imbalance can place stress on other joints and lead to secondary issues such as arthritis or ligament strain.
How Over-Exercise Causes Damage
Normal play is healthy. Controlled movement builds muscle and coordination.
The problem is excessive impact.
Repeated high-impact activity — especially during rapid growth phases — can damage developing joints. This includes:
Jumping on and off sofas or beds
Long walks beyond their developmental capacity
Repetitive running on hard surfaces
Forced jogging
Intense rough play
Slippery floors with no traction
Every big jump creates force between soft, forming bones. In moderation, that’s normal wear and tear. But repeated stress during early growth can interfere with proper skeletal development.
You only get one chance to grow them correctly.
When Are Puppies Most at Risk?
The fastest growth phase typically occurs between 4 and 8 months of age. During this time, growth plates are working hard and are particularly vulnerable.
In many medium-to-large breeds, growth plates begin closing around 8–12 months. However, some larger or more heavily built dogs may take 12–18 months (or longer) to fully mature.
Bully breeds vary depending on size and bloodline, so always monitor your individual dog’s development.
How Much Exercise Is Appropriate?
Five minutes of structured exercise per month of age.
For example:
3 months = 15 minutes
6 months = 30 minutes
Important: This refers to gentle, controlled exercise — not high-intensity jumping or sprinting.
A calm 30-minute walk is very different from 30 minutes of explosive running and bouncing.
Always:
Stop before your puppy becomes exhausted
Avoid forced exercise
Allow free rest periods
Prioritize safe footing and soft surfaces
Breeding + Upbringing = Structure
A well-built Bully is the result of two things:
Excellent breeding AND responsible upbringing.
Even the best genetics can be compromised by poor management during the growth phase.
Once your dog is fully mature, you’ll have years to enjoy:
Strength training
Conditioning
Longer walks
Performance work
Higher-impact play
But while they are still babies, your focus should be protection and controlled development.
You only get one opportunity to develop your Bully puppy’s foundation. Protect their growth plates now — and you’ll be rewarded with strength, balance, and soundness for life.
If you ever have concerns about your puppy’s development or exercise levels, speak with your breeder and veterinarian for breed-specific guidance.
The American Bully breed has grown rapidly in popularity over the last decade, leading to the development of several distinct size categories. While each variety shares the same bully foundation, the differences in height, build, and overall appearance can dramatically change the look and style of the dog.
Understanding these categories is important for breeders, owners, and enthusiasts who want to better understand the breed standard and the purpose behind each variation.
What Defines An American Bully Size Category?
Unlike many dog breeds that are separated by weight, American Bullies are primarily categorised by:
height at the withers
overall frame
body proportions
The withers are the highest point of the shoulder blades where the neck meets the back. Height should always be measured from the ground to the top of the withers while the dog is standing naturally on a flat surface.
Although each category differs in size, all American Bullies should still maintain:
bully breed characteristics
strong bone
muscular structure
broad appearance
balanced proportions
The Four Main American Bully Size Categories
Micro / Miniature Bully
Adult Male Height:
Under 14 inches at the withers
The Micro Bully is the smallest and most compact variation of the breed. These dogs are known for:
short stature
heavy bone
compact frames
large heads
exaggerated bully appearance
Micro Bullies have become extremely popular due to their unique look and strong visual presence despite their smaller size.
However, responsible breeding remains important to maintain:
structure
movement
breathing
functionality
Pocket Bully
Adult Male Height:
14 to 17 inches at the withers
The Pocket Bully is one of the most popular American Bully categories worldwide.
Despite the name “Pocket,” these dogs are still muscular and substantial in build. Pocket Bullies are simply shorter in height compared to the Standard category while maintaining:
bully type
broad chest
muscular appearance
compact proportions
Many enthusiasts appreciate the Pocket category because it balances:
compact size
family-friendly temperament
bully presence
manageable proportions
without becoming overly tall.
Standard Bully
Adult Male Height:
17 to 20 inches at the withers
The Standard American Bully is often considered the foundation size of the breed.
This category combines:
athleticism
muscularity
structure
bully characteristics
into a balanced overall package.
Standard Bullies typically display:
more athletic movement
cleaner structure
balanced proportions
functional build
while still maintaining the strong bully appearance the breed is known for.
Many breeders view the Standard category as one of the most versatile and structurally balanced variations.
Classic Bully
Adult Male Height:
17 to 20 inches at the withers
The Classic Bully shares the same height range as the Standard Bully but differs in overall body type.
Classic Bullies are generally:
leaner
lighter boned
less bulky
more athletic in appearance
compared to the heavier Standard style.
The Classic category was developed for enthusiasts who preferred:
a more traditional athletic build
cleaner movement
less exaggerated mass
while still maintaining American Bully breed characteristics.
XL Bully
Adult Male Height:
Over 20 inches at the withers
The XL Bully is the tallest variation within the breed.
XL Bullies are known for:
large frames
increased height
substantial muscle mass
powerful appearance
Despite their size, quality XL Bullies should still maintain:
balance
movement
sound structure
stable temperament
rather than appearing oversized or poorly proportioned.
A well-bred XL Bully should combine size with functionality.
Female Height Differences
Female American Bullies are generally:
approximately 1 inch shorter
than male height ranges across all categories.
Females should still maintain:
femininity
bully type
balanced structure
while fitting proportionally within their respective category.
Why Size Alone Does Not Determine Quality
True quality involves far more than height alone.
A quality American Bully should display:
sound structure
stable movement
good breathing
correct proportions
balanced temperament
overall functionality
regardless of size category.
Two dogs may fall within the same height range but look completely different based on:
structure
bone density
conditioning
genetics
overall balance
This is why experienced breeders evaluate the entire dog rather than focusing only on size.

The Importance Of Proper Measurement
Incorrect measurement is extremely common online and can create confusion regarding a dog’s actual category.
American Bullies should always be measured:
standing naturally
on level ground
from the ground to the top of the withers
Measuring to the head, neck, ears or below the shoulders is inaccurate and does not follow proper breed measurement standards.
Accurate measurement helps maintain consistency and integrity within the breed.
Final Thoughts
The American Bully breed offers a wide range of styles and sizes, which is one reason for its growing worldwide popularity.
From the compact Micro Bully to the towering XL Bully, each category brings its own unique appearance and appeal while still sharing the same bully foundation.
However, regardless of size, the future of the breed depends on maintaining:
structure
movement
temperament
health
overall functionality
alongside visual bully characteristics.
Understanding these size categories helps owners and enthusiasts better appreciate the diversity and development of the American Bully breed.

The American Bully breed has a wide range of styles. Some dogs display more “classic lean” traits, while others carry heavier “extreme” features. Understanding the difference helps explain why breeders often combine both styles in breeding programs.
The image below illustrates a sample of the Pocket Bully class. The same male body-type variations apply across all American Bully classes.
American Bully Extreme Features vs Lean/Classic Features
Lean / Classic Features
Lean or classic-type Bullies usually show:
More athletic and functional movement
Lighter bone and less overall mass
Longer muzzle and cleaner facial structure
More visible tuck-up and waist definition
Higher resemblance to older APBT/terrier influence
Moderate chest, shoulders and head size
These dogs are often described as:
Cleaner
Sportier
More agile
More moderate in appearance
However, “lean” does not automatically mean:
structurally correct,
healthy,
or temperament sound.
A lean dog can still have:
weak fronts,
poor rear angulation,
bad movement,
breathing issues,
unstable nerves,
lack bully presence
or incorrect temperament.
Structure, health and temperament depend on genetics, selection and breeding decisions — not simply body size.
Extreme Features
Extreme-style Bullies are bred for:
More muscle mass
Heavier bone density
Larger head size
Wider chest and shoulders
Shorter compact body
More substance and “bully presence”
Thick neck and exaggerated features
The goal is often a dog with:
powerful appearance,
heavy mass,
and strong visual impact while still maintaining functional movement and stability.
Why Lean Dogs Often Need Extreme Blood
Many lean/classic dogs lack:
enough bone,
head size,
chest width,
or overall substance.
Because of this, breeders often introduce extreme bloodlines to:
increase mass,
improve head type,
add width,
and create more bully expression.
Without stronger mass genetics, offspring from two lean dogs commonly remain:
lighter framed,
more terrier influenced,
and less “bully” in appearance.
Producing True Extreme Offspring Is Rare
Producing genuine extreme offspring consistently is difficult because genetics naturally pull many puppies back toward moderate or lean traits.
Even when using one extreme parent:
many pups still mature closer to classic/lean structure,
lighter bone,
or terrier-style proportions.
This is why truly balanced extreme dogs are uncommon.
A breeder may produce:
only one or two standout extreme pups (sometime neither) in an entire litter,
while the rest mature more moderate.
Extreme traits are not guaranteed simply by breeding two heavy dogs together. Correct structure, health, movement and temperament still need to be maintained alongside mass.
Balanced Goal
The ideal goal for many breeders is not simply:
“lean” or “extreme,”
but rather:
a balanced American Bully with:
correct structure,
sound movement,
stable temperament,
good health,
and strong bully breed type.
The challenge is achieving:
mass without dysfunction,
compactness without restriction,
and bully presence without sacrificing athletic ability.
What is Bully Presence
“Lack bully presence” refers to a dog that does not visually project the strong, powerful, unmistakable American Bully look.
Regardless of their classification determined by their adult heights in class Pocket Bully, Standard Bully, XL Bully, Micro/Miniature Bully.
The American Bully should give the impression of great strength for its size. It is a compact and medium/large size dog with a muscular body and blocky head. The American Bully should have the appearance of heavy bone structure with a bulky build and look. Bred as a companion dog, intelligent, exhibiting confidence, a zest for life, along with an exuberant willingness to please and bond with their family.
Following ABKC President Dave Wilson’s announcement of the Nationals Alternative Variety Showcase, the alternative variety includes Miniature Bully (Micro Bully), Blotch Bully (Merle Bully) and Extreme Bully. The American Bully community has expressed mixed reactions.
As the event approaches, questions arise about the EXTREME Variety versions of the breed. The American Bully is inherently an extreme breed, but how extreme are we really discussing in this Extreme Bully Variety exhibit show? What traits and features are they looking for? The community has successfully showcased some notably extreme dogs, but are we referring to dogs that are out of type such as more exaggerated features or those that simply don’t conform to the standards? This concern exists across all varieties.
There is also concern that the term “extreme” often excuses dogs that aren’t well-structured. It has been proven that a well-balanced dog can achieve the desired muscle, size, and mass. Labeling a dog as extreme can suggest an overdone appearance that misaligns with the breed’s standard.
Many are questioning what defines “extreme,” especially as we see dogs that surpass current standards.
The American Bully is expected to embody Extreme Bully characteristics and features. The ABKC has previously noted that the original Extreme Bully class was removed from their registry because these traits should already be integral to the American Bully breed standard.
On the other hand, some of the community appreciate the opportunity for varieties like Merle, Miniature, and Extreme Bullies to be showcased, emphasizing that these dogs deserve recognition and offering excitement for quality dogs to gain a platform.
Conversely, critics argue that Merle Bullies, an essential part of the breed’s history, are being sidelined. Some fear that introducing these varieties might dilute the breed standard, leading to lower-quality breeding practices.
Public opinion remains divided. Some suggest that those dissatisfied with the changes should create their own registry, seeing this shift as an opportunity for growth. Others express frustration that the Nationals should prioritize top-tier dogs that adhere to traditional standards rather than experimenting with new varieties.
While the new showcase aims to promote diversity and inclusivity, it’s evident that opinions vary regarding its potential impact on the breed’s future.
Is this the next phase of development for the breed?
This showcase provides our community, especially the minority, with a chance to present these types to a wider audience. It also highlights what these “types” look like today and where they stand in their development. Such as the Miniature Bully (Micro Bully) these dogs share the same functionality as the current pocket variety. The same goes for Merle’s, do they adhere to the standard as far as conformation. It’s a fun event and an opportunity to showcase the best of these breeds in relation to the ABKC.
In young breeds, like the American Bully and all of these (American Bully varieties), change is inevitable as they develop. Early on, many breeds began to emerge, some evolving while others did not. Trends shift, leading to population growth, and what was once in style can quickly fall out of favor. New registries are constantly emerging to adapt to these changes.
The American Bully is still a young breed and far from finished developing. It is evolving, not just changing. We now have a wealth of quality breeding stock, which means we no longer need to rely on terrier-type dogs. It’s important to focus on breeding for true American Bully type.
“Without type, the identity of the breed is lost.”

Pocket Bullies are a small version of the American Bully breed. They usually stand about 14 to 17 inches tall at the shoulders (comparative in size height between the Staffordshire bull terrier with a more muscular thick build and English Bulldog and weigh between 15kg to 40kg. Pocket Bully with their muscular build and intimidating appearance yet friendly face, many people wonder if they would make good family pets.
What Are They Like?
Pocket Bullies are known for being friendly and loving. They love spending time with people and often get along well with kids. Even though they look tough, they can be very gentle and playful, making them great companions for families.
Training and Socializing
Just like all dogs, Pocket Bullies need to learn how to behave. It’s important to train them when they are young. Taking them to new places, meeting different people, and playing with other animals can help them grow up to be happy and well-mannered. Using treats and praise helps them learn best!
How Much Exercise Do They Need?
Pocket Bullies are medium to low energetic dog, a bit less than a Staffordshire bull terrier, yet a bit more energy than an English Bulldog and love to play. They need regular exercise, like daily walks and fun games, to stay healthy and happy. They make great playmates for families who enjoy outdoor and indoor activities, but they don’t need as much space or exercise as some larger breeds, so they can do well in homes or apartments and prefer to be a lounge or home lap dog.
Health Tips
Most Pocket Bullies are healthy, but like all dogs, they can have some health issues. Regular check-ups with a vet, a good diet, and enough exercise are important for keeping them healthy. If you’re thinking about getting one, it’s a good idea to find a responsible breeder who takes care of their dogs’ health.
Good with Kids and Other Pets
Pocket Bullies are usually great with kids. They love to play and can be very gentle. However, it’s important to always supervise them when they are with young children to keep everyone safe. They can also get along with other pets if introduced carefully.
Conclusion
In short, Pocket Bullies can be wonderful family pets! They are loving, playful, and adaptable, making them great companions. If your family is ready to spend time training and exercising a dog, a Pocket Bully could be a fantastic addition to your home. Just remember, every dog needs love and care to thrive!
