American Bully vs American Bulldog Differences: Which Breed is Right for You?

Can you tell the difference between these two muscular powerhouses at a glance? Many people confuse them, but understanding the american bully vs american bulldog differences is critical before you bring a puppy home. While they share similar names and blocky heads, they are distinct breeds with very different energy levels, histories, and needs.

If you are looking for a high-drive working dog that can run for miles, you will be disappointed with a heavy-set American Bully. Conversely, if you want a chill companion for a small home, an energetic American Bulldog might destroy your furniture out of boredom.

This guide breaks down everything you need to know. We will look at size, cost, health, and temperament to help you decide which breed fits your lifestyle in 2026.

The Main Differences at a Glance

Before we look at the details, here is a quick comparison table to see how these breeds stack up against each other.

Origin and History

To understand why these dogs act differently, you have to look at why they were bred.

The American Bulldog: A Working Legacy

The American Bulldog is the older of the two breeds. It descends directly from the Old English Bulldogs brought to the American South by immigrants. Farmers used these dogs for real work. They caught wild cattle, guarded property, and hunted invasive wild pigs.

Because they were working dogs, they had to be athletic. They needed the stamina to run and the courage to hold down a large animal. This history means the modern American Bulldog still has a lot of “drive.” They want a job to do.

The American Bully: The Modern Companion

The American Bully is a much newer breed. It was developed in the United States during the 1980s and 1990s. Breeders crossed the American Pit Bull Terrier and American Staffordshire Terrier with various bulldog breeds (including the American Bulldog and English Bulldog).

The goal was specific. Breeders wanted the tough look of a Pit Bull but with the aggression bred out. They aimed for a dog with a heavy bone structure that would be happy sitting on the couch with the family. The American Bully was recognized by the ABKC in 2004 as a distinct breed designed solely for companionship.

Never assume an American Bully is a “Pit Bull.” While they share ancestry, the American Bully has been bred specifically for a lower prey drive and a stable, non-aggressive temperament suitable for families.

Physical Appearance and Size

This is where the confusion often starts, but also where the differences are most visible once you know what to look for.

American Bulldog Structure

American Bulldogs are generally taller and leggier. They look like athletes. There are two main types:

• Scott Type (Standard): Sleek, athletic, and looks like a large, white Pit Bull. They are built for speed and catching.
• Johnson Type (Bully): Larger, wider, and has a shorter muzzle. They look more like a classic bulldog but are still taller than an American Bully.

Males typically stand 20 to 28 inches tall and can weigh between 60 and 120 pounds.

American Bully Structure

The American Bully is built like a tank. They have a lower center of gravity, wider chests, and heavier bone density than American Bulldogs. They come in four distinct classes recognized by the ABKC:

1. Pocket: Under 17 inches at the shoulder.
2. Standard: 17 to 20 inches.
3. Classic: Same height as Standard but with a lighter frame (closer to a Pit Bull look).
4. XL: Over 20 inches (up to 23 inches for males).

Even a shorter American Bully often weighs as much as a taller American Bulldog because of their muscle mass. If you are interested in the larger variety, you should read our guide on the XL American Bully to understand their specific space requirements.

Temperament and Family Life

The personality of the dog is the most important factor for most owners. This is where the american bully vs american bulldog differences really shine.

American Bully Personality

The American Bully is known for being a “lover, not a fighter.” Reputable breeders have spent 30 years selecting for friendliness. They are often described as having a “nanny” temperament because they are exceptionally patient with children.

They are generally:

• Eager to please.
• Affectionate and cuddly.
• Low aggression toward other dogs (if socialized).
• Moderate energy (happy with a walk and a nap).

However, because they are strong dogs, they still need guidance. You can learn more about their personality in our deep dive on American Bully temperament.

American Bulldog Personality

The American Bulldog is a working breed. They are loyal and loving, but they are also more assertive. They have a higher prey drive, which means they might chase cats or squirrels more often than an American Bully would.

They are generally:

• High energy and boisterous.
• Protective of their home and family.
• Confident and sometimes stubborn.
• Need vigorous exercise to stay happy.

An American Bulldog is more likely to be a good guard dog, while an American Bully is more likely to show a burglar where the treats are kept.

Exercise and Training Needs

Training the American Bulldog

You need to be a confident leader with an American Bulldog. They are smart but can be independent. If you do not give them rules, they will make their own. They excel in dog sports like weight pulling, agility, or obedience because they love having a job.

Training the American Bully

American Bullies are generally easier to train for the average owner because they are so food-motivated and eager to please. They respond very well to positive reinforcement.

The biggest challenge with Bullies is usually their physical strength. You must teach them loose-leash walking early, or they will pull you down the street.

Start socialization immediately. Both breeds are powerful. A 100lb dog that fears strangers is dangerous. Introduce your puppy to 100 new people and 50 new dogs in their first few months to ensure a stable adult temperament.

Health and Lifespan

Both breeds are generally healthy, but their body shapes predispose them to different issues.

Shared Health Risks

• Hip Dysplasia: Both breeds are heavy and prone to joint issues.
• Skin Allergies: Itchy skin and hot spots are common in both.
• Cherry Eye: A protruding gland in the eye that often requires surgery.

American Bulldog Specifics

Because they are active and large, American Bulldogs are prone to tearing their cruciate ligaments (CCL) in their knees. They can also suffer from bone cancer (osteosarcoma) at higher rates than smaller breeds. They typically live 10 to 15 years.

American Bully Specifics

The American Bully’s heavy build puts immense pressure on their joints. You must be careful not to over-exercise puppies. They are also prone to cardiac issues if the breeder did not test the parents.

In the UK, the XL variety has faced scrutiny regarding health and conformation. If you own a Bully, you must be vigilant about [common health problems](https://bullyowners.com/american-bully-health-problems/) like elbow dysplasia and heart conditions.

Grooming and Maintenance

This is an area where both breeds are very similar.

• Coat: Both have short, stiff coats that shed moderately. A weekly brush with a rubber mitt is usually enough.
• Drool: American Bulldogs tend to slobber more, especially after drinking or eating. American Bullies vary, but those with looser jowls will also drool.
• Wrinkles: If your dog has folds on their face (more common in Bullies), you must clean them daily to prevent bacterial infections.

Cost Comparison: US and UK

Price is a major differentiator. American Bullies are currently one of the most expensive dog breeds due to their popularity and the “hype” around specific bloodlines.

American Bully Pricing

• US Price: A pet-quality puppy usually costs $2,000 to $5,000. Puppies from famous bloodlines or with unique colors (like lilac or merle) can reach $10,000+.
• UK Price: Expect to pay £1,500 to £4,000 for a standard puppy.

American Bulldog Pricing

• US Price: Typically $1,500 to $3,000.
• UK Price: Usually £1,000 to £2,500.

Because American Bulldogs are an older, more established breed without as much “designer” hype, their prices are generally more stable and affordable.

Legal Considerations and BSL

This is the most serious section of this guide. Depending on where you live, owning one of these breeds might be difficult or illegal.

In the United States

There is no federal ban on either breed. However, Breed Specific Legislation (BSL) exists in many cities and counties.

• Misidentification: Animal control officers often label both breeds as “Pit Bulls.” If your city bans Pit Bulls, your American Bully or American Bulldog could be seized.
• Housing: Many landlords ban “bully breeds.”
• Insurance: Getting homeowners insurance can be a nightmare. Companies like Allstate and Nationwide often have restrictions.

Before buying, call your home insurance provider. Ask specifically if they cover “American Bulldogs” or “American Bullies.” If they say no, check with State Farm, which historically does not discriminate by breed.

In the United Kingdom

• American Bulldog: Currently legal to own and breed.
• American Bully: The XL Bully type is banned in England and Wales (as of 2024). You must have a Certificate of Exemption, third-party insurance, and the dog must be muzzled in public.
• Other Sizes: Pocket, Standard, and Classic American Bullies are NOT banned, but they must not meet the physical measurements of an XL.

No. The American Bulldog is an older working breed descended from catch dogs. The American Bully is a modern companion breed created by mixing Pit Bulls, AmStaffs, and various bulldogs to create a family-friendly temperament.

Generally, the American Bully is considered better for families with young children due to its “nanny” temperament and lower energy. American Bulldogs are also great family dogs but are more boisterous and require more supervision due to their size and energy.

Neither breed is inherently aggressive if raised correctly. However, American Bulldogs have a higher prey drive and protective instinct. American Bullies have been specifically bred to have low aggression levels.

The American Bulldog is typically taller and more athletic. The American Bully is shorter but often wider and heavier for its size. An XL American Bully can weigh more than a standard American Bulldog, but it will usually be shorter at the shoulder.

A Pocket or Standard American Bully can do well in an apartment if walked daily. American Bulldogs are generally too high-energy and large for small apartments and do better with a yard.
