GuideToPitbull.com — UKC, ABKC & Breed Standard Sources
This article draws on official breed standards from the United Kennel Club (UKC), the American Bully Kennel Club (ABKC), and the American Dog Breeders Association (ADBA). All size measurements, weight ranges, and temperament descriptions reflect official breed standard documentation. This guide presents both breeds honestly — including challenges — to help owners make genuinely informed decisions.

The American Bully and the Pitbull are confused for each other every single day — in shelters, in breed-specific legislation debates, in social media, and in the minds of people who see a muscular, broad-chested dog and apply a single label to all of them. They are not the same breed. They do not have the same history, the same build, the same temperament profile, or the same ownership requirements. This guide gives you the complete, accurate comparison — the real history of each breed, every physical difference broken down precisely, the honest temperament data, the size classes that make American Bullies uniquely complex, the health differences, the cost difference, and a direct, honest assessment of which breed fits which type of owner.

📋 Key Takeaways
  • The American Bully is NOT a Pitbull — it is a separate breed recognized by the UKC in 2013 and the ABKC in 2004
  • The APBT (Pitbull) dates to 1800s England; the American Bully was developed in the USA in the 1980s–1990s
  • Pitbulls are lean, athletic, high-energy working dogs; American Bullies are heavier, calmer, companion-bred dogs
  • American Bullies come in 4 size classes — Pocket, Standard, Classic, XL — with significantly different size ranges
  • The American Bully breed standard explicitly identifies aggression as a disqualifying fault — it was bred out intentionally
  • American Bullies cost significantly more — $2,000 to $20,000+ vs $500 to $2,000 for APBT from reputable breeders
  • Both breeds need early socialization and positive training — neither is suitable for neglectful or inexperienced owners

History and Origin: Two Completely Different Stories

The American Pit Bull Terrier — A Working Dog from 1800s England

The American Pit Bull Terrier’s history begins in 19th-century England, where breeders crossed Old English Bulldogs with terrier-type dogs to create an animal combining the bulldog’s strength and tenacity with the terrier’s speed, intelligence, and drive. These dogs were initially used in blood sports — bull-baiting and dog fighting — which were eventually outlawed. When the breed arrived in the United States with immigrant communities, it was quickly repurposed as a versatile farm dog, guard dog, hunting companion, and family pet. The UKC formally recognized the American Pit Bull Terrier in 1898, making it one of the oldest recognized working breeds in the United States. Throughout the early and mid-20th century, the APBT was among the most popular family dogs in America, appearing in wartime recruitment posters as a symbol of loyalty and resilience.

The American Bully — A Purpose-Built Companion from the 1990s

The American Bully is a genuinely modern breed. Development began in the late 1980s and accelerated through the 1990s, primarily on the East and West Coasts of the United States. Breeders combined the APBT with American Staffordshire Terriers, American Bulldogs, English Bulldogs, and in some lines, Olde English Bulldogges — with a single clear purpose: to create a companion dog with the loyal, human-focused temperament of the pit bull type but a calmer energy level, broader physical presence, and reduced animal aggression. The American Bully Kennel Club (ABKC) was established in 2004, and the United Kennel Club recognized the American Bully as its own distinct breed in 2013. Today it is one of the fastest-growing breeds globally.

Physical Differences: How to Tell Them Apart

In photographs, the American Bully and the APBT can look remarkably similar. In person, the differences are immediately obvious to anyone who knows what to look for. The APBT is built like a natural athlete — lean, proportionate, and agile, with a frame designed for endurance and speed. The American Bully is built for presence — wider, heavier, and more exaggerated in muscular development, with a larger, broader head and a lower, more compact stance.

Physical Feature APBT (Pitbull) American Bully Key Difference
Overall Build Lean, athletic, proportionate Stocky, broad, heavily muscled Major
Weight 30–65 lbs 25–120+ lbs (by class) Very Major
Height 17–21 inches 13–23 inches (by class) Moderate
Head Shape Medium — proportionate to body Large, wide, pronounced stop Major
Chest Deep, moderately wide Very broad, wide, prominent Major
Legs Long, proportionate — agile Shorter relative to body — compact Moderate
Snout Length Medium-long snout Shorter, broader snout Moderate
Coat Colors Standard range — fewer variations Wide array incl. tricolor, merle Minor
Movement Light, agile, flowing gait Powerful, deliberate, wide stance Major
💡 The Easiest Visual Test: Look at the dog’s legs relative to its chest width. A Pitbull’s legs appear proportionate to its body. An American Bully’s chest is so wide that its legs appear to be set far apart — sometimes described as a dog that looks too muscular for its own legs. This disproportionate width-to-height ratio is a defining visual characteristic of the American Bully across all size classes.

American Bully Size Classes Explained — vs Pitbull

One of the most confusing aspects of the American Bully is its four official size classes, each recognized separately by the ABKC and UKC with distinct breed standards. Understanding these classes is essential because a Pocket Bully and an XL Bully are dramatically different dogs — in size, cost, health considerations, and care requirements — yet both are “American Bullies” by breed registration.

Size Class Male Height Female Height Typical Weight Build Character Vs Pitbull
APBT (Reference) 18–21 inches 17–20 inches 30–65 lbs Lean, athletic
Pocket Bully Under 17 inches Under 16 inches 11–24 lbs Very compact, low Smaller
Standard Bully 17–20 inches 16–19 inches 44–88 lbs Heavy, broad Heavier
Classic Bully 17–20 inches 16–19 inches 44–77 lbs Lighter frame Slightly heavier
XL Bully 20–23 inches 19–22 inches 80–120 lbs Very large, massive Much larger

* Measurements per ABKC and UKC official breed standards. Actual weights vary. “Extreme” class exists in some registries but is not universally recognized and often involves health-compromising exaggerations.

Temperament: The Most Important Difference

The temperament difference between the American Bully and the APBT is deliberate and documented — it was the primary reason the American Bully was developed as a separate breed. Breeders specifically selected against the higher prey drive, dog-directed aggression risk, and intense working drive of the APBT to create a calmer, more universally compatible companion dog. The result is two dogs that both love people intensely but express that love very differently in daily life.

🔵 APBT (Pitbull) Temperament
  • High energy — constantly active and engaged
  • Intense focus — locks onto tasks and goals
  • Strong prey drive — may chase small animals
  • Dog aggression possible in some individuals
  • Extremely loyal — bonds deeply with owner
  • Highly trainable — eager and responsive
  • Thrives with a job or athletic outlet
  • May be headstrong without consistent leadership
🟣 American Bully Temperament
  • Calmer energy — more settled indoors
  • Extremely people-oriented — “velcro dog”
  • Dog aggression: breed standard = disqualifying fault
  • Excellent with children — very patient
  • Less prey drive than APBT
  • Trainable — motivated by praise and food
  • Less suited to high-intensity sport
  • Can be stubborn — short training sessions work best
💡 Important Clarification: The American Bully breed standard lists “viciousness or extreme shyness” and “aggressive behavior toward humans” as disqualifying faults. This means a Bully that shows human aggression cannot be shown and should not be bred. This standard was intentionally designed to create a breed that is safer and more universally compatible than historical fighting dog lineages — it was engineered into the breed from the beginning.

Health, Cost and Care: Practical Ownership Differences

Ownership Factor APBT (Pitbull) American Bully Advantage
Purchase Price $500–$2,000 $2,000–$20,000+ APBT
Exercise Need 60–90 min daily 30–60 min daily Bully
Grooming Low — weekly brush Low — weekly brush Equal
Lifespan 12–16 years 10–13 years APBT
Hip Dysplasia Risk Moderate Higher (larger classes) APBT
Breathing Issues Low (normal snout) Some lines — BOAS risk APBT
Skin Allergies Common in breed Common in breed Equal
Heart Conditions Occasional Some lines — more prevalent APBT
Training Ease High — driven and focused Good — food motivated APBT slight edge
BSL Risk High — frequently named Increasing — often included Similar risk
⚠️ American Bully Health Warnings — XL and Extreme Classes
  • Brachycephalic Obstructive Airway Syndrome (BOAS) — some heavily bred lines have shortened snouts that cause breathing difficulties, especially in heat or during exercise
  • Joint stress in XL lines — extreme weight on a relatively short skeletal frame creates hip, elbow, and spine pressure that causes early arthritis
  • Cardiac issues — some bloodlines show higher rates of heart conditions, particularly in Extreme class dogs
  • Responsible breeder selection is critical — always ask for OFA hip and elbow certifications, cardiac clearances, and health-tested parents before purchasing any American Bully

Frequently Asked Questions

Are American Bullies and Pitbulls the same breed?
No. The American Bully and the American Pit Bull Terrier are two entirely separate breeds with distinct breed standards, registries, and development histories. The American Bully was developed in the 1980s and 1990s and recognized by the UKC in 2013 as its own distinct breed. They share ancestry through the APBT but differ significantly in build, temperament, purpose, size, and care requirements. Calling them the same breed is inaccurate — it would be similar to calling a Labrador and a Golden Retriever the same dog because they share common ancestors.
What is the main difference between an American Bully and a Pitbull?
The most significant differences are build and temperament. The APBT is a lean, athletic, high-drive working dog with a proportionate build optimized for endurance and agility. The American Bully is a heavier, broader companion dog with a more exaggerated muscular build, calmer energy level, and a breed standard that explicitly identifies aggression as a disqualifying fault. In practical daily life, the APBT needs significantly more exercise and mental stimulation; the American Bully is more suited to calmer household routines.
Which is bigger — American Bully or Pitbull?
For most American Bully classes, the Bully is heavier — sometimes dramatically so. XL Bullies can weigh 80 to 120+ pounds compared to the Pitbull’s 30 to 65 pounds. However, Pocket Bullies are actually smaller than Pitbulls in height. The Classic Bully class is similar in height to the APBT but significantly heavier in build. Height ranges overlap considerably between the breeds — weight and overall build are more reliable differentiators than height alone.
Is the American Bully more aggressive than the Pitbull?
No. The American Bully breed standard explicitly lists human aggression and dog aggression as highly undesirable and disqualifying traits. The breed was specifically developed to reduce the animal aggression and high prey drive of the APBT. Responsibly bred American Bullies are known for their extremely stable, tolerant temperament. The APBT can show dog-directed aggression in some individuals, but is not inherently human-aggressive. Both breeds need proper socialization — neither is inherently dangerous when responsibly bred and raised.
How much does an American Bully cost compared to a Pitbull?
American Bullies cost significantly more. Standard American Bullies from reputable breeders typically range from $2,000 to $5,000. XL class dogs from established bloodlines can cost $5,000 to $15,000. Rare color variants or highly sought-after bloodlines can exceed $20,000. American Pit Bull Terriers from reputable breeders typically cost $500 to $2,000. Both breeds are available through rescue organizations for $100 to $500 in adoption fees — the strongly recommended option for most families.
Which breed is better for families?
Both can be excellent family dogs with proper breeding, socialization, and training. The American Bully is often the more naturally suitable choice for families with young children due to its calmer energy, exceptional patience, and lower likelihood of dog-directed aggression. The APBT is an outstanding family dog for active households that can provide 60 to 90 minutes of daily exercise, consistent training, and proper socialization. The right choice depends on your activity level, experience with dogs, and household composition.
Do American Bullies have more health problems?
Some American Bully lines — particularly XL and Extreme classes — carry higher health risks due to their exaggerated build. Joint stress, Brachycephalic Obstructive Airway Syndrome (BOAS) in shorter-snouted lines, cardiac conditions, and obesity-related issues are more prevalent in some Bully lines than in the APBT. The APBT generally has a longer lifespan (12–16 years vs 10–13 years for most Bully classes). Selecting from health-tested parents with OFA-certified hips and elbows reduces risk significantly in both breeds.
Is the American Bully recognized by the AKC?
No. As of 2026, the American Bully is not AKC-recognized. It is recognized by the American Bully Kennel Club (ABKC, established 2004), the United Kennel Club (UKC, since 2013), and several international registries including the European Bully Kennel Club (EBKC). The APBT is also not AKC-recognized but is recognized by the UKC (since 1898) and the ADBA. The American Staffordshire Terrier — derived from the same lineage — is the AKC-recognized relative of the APBT.

Final Verdict: Two Different Dogs for Two Different Owners

The confusion between American Bullies and Pitbulls persists because they look similar and share ancestry. But in every way that matters to an owner — energy level, exercise requirement, temperament, health considerations, cost, and the daily experience of living with them — they are genuinely different dogs that suit different types of owners.

The APBT is for the active, experienced owner who wants a driven, athletic, highly trainable working dog with exceptional loyalty and a long history as one of America’s most versatile breeds. The American Bully is for the owner who wants that same depth of human connection and loyalty in a calmer, heavier, more physically impressive package that is better suited to relaxed family life and requires less intense daily management.

Neither is better. Both require responsible ownership. The right choice is the one that genuinely matches how you actually live — not how you imagine you might live with a dog you haven’t yet met.

Note: This article provides general breed comparison information based on UKC, ABKC, and ADBA official breed standards. Individual dogs vary significantly regardless of breed. Both breeds require health testing, responsible breeding, early socialization, and consistent training. Always verify local breed-specific legislation before acquiring either breed.
