Meet the 150-Pound Bully and 9 Other Biggest Pit Bull Dogs

Think Pit Bulls are all medium-sized muscle machines? Think again.

Some of these dogs tip the scale at over 100 pounds—and one famous brute clocks in at a jaw-dropping 150.

These aren’t your average backyard pups. They’re the heavyweights of the bully world, packing mass, muscle, and presence into every step.

Some come from pure Pit Bull lines bred for size. Others are crosses with giants like Mastiffs and Cane Corsos. But don’t let their intimidating looks fool you—many of these dogs are gentle, loyal, and love a good cuddle session.

Still, their size demands respect and responsible ownership. If you thought the Pit Bull world was all about agility and energy, meet the bulkiest bullies on the block.

Here are the 10 biggest Pit Bull breeds you’ll ever see—ranked from huge to absolutely colossal.

10. Olde English Bulldogge x Pit Bull

This mix brings together the solid muscle of the Olde English Bulldogge and the athleticism of the American Pit Bull Terrier. While the Olde English Bulldogge was bred to be a healthier, more agile version of the original bulldog, pairing it with a Pit Bull creates a dog that’s thick, powerful, and surprisingly nimble.

These hybrids often weigh 80 to 100 pounds, and while they have a bulky build, they’re not lazy. They’re agile, quick to react, and full of personality. Owners often report a dog that’s as goofy as it is imposing. Though they look like mini tanks, they thrive on companionship and thrive in homes where they’re engaged both mentally and physically. With proper training, this mix can be a loyal and loving family protector—just don’t expect them to go unnoticed at the dog park.

9. Alapaha Blue Blood Bulldog

Though not technically a Pit Bull, the Alapaha Blue Blood Bulldog is often mistaken for one due to its stocky frame and square head. Bred in the American South as a protective farm dog, this rare breed carries itself with confidence and power. Males can tip the scale at over 100 pounds, with a frame that’s all business.

Despite their intimidating appearance, Alapahas are extremely loyal and affectionate with their families. They’re known for being great with kids, but protective when it comes to strangers. This isn’t a breed for first-time dog owners—they need consistent training and clear leadership to avoid stubborn behavior. With the right upbringing, they make devoted companions who are always ready to defend their home turf. If you’re looking for something unique and powerful, the Alapaha is a rare gem in the bully-type family.

8. Mastiff x Pit Bull Mix

When a Pit Bull meets a Mastiff, you get a hybrid that combines sheer power with unwavering loyalty. These mixes can weigh between 100 and 140 pounds, depending on which Mastiff breed is in the mix—English, Neapolitan, or Bullmastiff. Regardless, the result is a dog with massive jaws, a broad chest, and a heart that often matches its size.

These dogs tend to be naturally protective and can make excellent guard dogs, but early socialization is crucial to ensure they don’t become overzealous. They’re incredibly loyal to their people but can be wary of strangers and other animals. Their large frame needs space, and their thick muscles require consistent exercise. For experienced owners who can handle their strength, this mix offers the ultimate combination of size, affection, and loyalty in one unforgettable package.

7. Rottweiler x Pit Bull Mix (Pitweiler)

The Pitweiler is a powerful blend of two assertive breeds, combining the muscular Pit Bull with the already-impressive Rottweiler. These dogs are stocky, athletic, and imposing—with many tipping the scale at over 100 pounds. They’re alert, intelligent, and bred to protect, so it’s no surprise they’re often used in security work.

Despite their tough exterior, Pitweilers are deeply loyal to their families and can be total softies at home. They bond closely with their owners and thrive when given structure and purpose. Without proper training and leadership, however, they can become stubborn and difficult to manage. These dogs aren’t for the faint of heart—but for someone who knows how to handle a strong-willed, intelligent canine, the Pitweiler can be a fiercely loyal and impressive companion with strength that turns heads.

6. American Bulldog x Pit Bull (Bullypit)

Bullypits are a dynamic mix that combines the stocky frame of the American Bulldog with the agility of the Pit Bull. These dogs usually weigh between 80 and 120 pounds and bring an imposing presence wherever they go. With a thick neck, broad shoulders, and defined muscles, they look like bodybuilders in fur coats.

But it’s not just about looks. Bullypits are known for their affectionate nature and strong family bonds. They’re protective without being overly aggressive and often have a goofy, playful side that makes them great with kids. That said, their strength demands consistent training, and early socialization is key to avoiding behavioral issues. For experienced dog owners looking for a dog with both heart and heft, the Bullypit offers a well-rounded blend of loyalty, power, and personality in one powerful package.

5. Cane Corso x Pit Bull Mix (Corso Pit)

Combining the regal Cane Corso with a Pit Bull results in a hybrid that’s both intimidating and intelligent. These dogs often reach 100 to 130 pounds and have a serious, watchful demeanor that makes them natural protectors. With the Cane Corso’s guarding instincts and the Pit Bull’s athleticism, this mix isn’t one to mess with.

Despite their size and confidence, Corso Pits can be deeply loyal and affectionate with their families. They’re highly trainable but require experienced owners who can provide firm, consistent leadership. Without proper guidance, their protective nature can become overbearing or even reactive. These dogs do best in active households where they’re given a job or purpose. If you want a guardian who can also double as a loyal friend, this hybrid brings brains, brawn, and bravery to the table.

4. American Pit Bull Terrier (Large Strain)

While the standard American Pit Bull Terrier typically ranges from 35 to 60 pounds, some strains—especially those bred for strength sports like weight-pulling—grow significantly larger. These large-boned APBTs can hit 85+ pounds, packing solid muscle onto a still-agile frame that can surprise anyone who assumes Pit Bulls are only mid-sized.

Despite their intimidating build, these dogs are often social butterflies. They’re known for being loving, eager to please, and deeply bonded to their humans. When properly trained, they’re gentle, loyal companions who excel in everything from agility to obedience. Because they carry such strong instincts and drive, these bigger APBTs need plenty of mental and physical stimulation. They might not be the flashiest crossbreed, but don’t count them out—these oversized originals are as tough as they are loyal.

3. American Bully XL

Slightly smaller than the XXL but still enormous by most standards, the American Bully XL can weigh up to 130 pounds. These dogs are known for their wide stance, muscular build, and deeply affectionate personalities. They often look intimidating but tend to be sweet-natured and great with children.

Originally developed from the American Pit Bull Terrier, American Staffordshire Terrier, and other bull breeds, XL Bullies were bred to emphasize size and stability in temperament. They’re generally calm, confident, and easygoing—making them excellent family dogs for the right home. Because of their bulk, they do need firm training from an early age to ensure good manners. If you’re looking for a large companion with a mellow temperament and a loyal heart, the American Bully XL could be your gentle giant of choice.

2. American Bully XXL

Meet the bodybuilders of the Bully breed world. American Bully XXLs are a sight to behold, often weighing more than 140 pounds and carrying muscle on top of muscle. Bred specifically for size and temperament, they have an exaggerated build with massive chests, thick necks, and powerful legs.

Despite their fearsome appearance, these dogs are usually big softies. They’re known for being incredibly affectionate with family members and surprisingly tolerant of children and other pets. Because they were bred for companionship rather than work or sport, they don’t require as much exercise as other large breeds—but they still benefit from daily activity. Due to their size, they need experienced handling and regular socialization to stay balanced. The XXL Bully isn’t just a pet—it’s a presence. If you want size, personality, and loyalty in one oversized package, this breed delivers.

1. Hulk (The 150-Pound Bully)

Topping the list is the one and only Hulk, the colossal American Bully owned by Dark Dynasty K9s. At over 150 pounds, he defies every stereotype about Pit Bulls being medium-sized. His massive frame, blocky head, and rippling muscles made him a viral sensation—and he’s passed those genes on to multiple oversized offspring.

But what’s most surprising about Hulk isn’t his size—it’s his personality. By all accounts, he’s a sweet, affectionate family dog who plays gently with children and lives peacefully with other dogs. He’s also a trained protection dog, proving that brains can match brawn. Hulk isn’t just big for show—he’s the poster dog for what careful, responsible breeding can achieve. Whether you’re amazed, inspired, or a little intimidated, there’s no denying it: Hulk is the undisputed heavyweight champ of the bully world.
