When it comes to pitbulls, there’s often confusion about what exactly constitutes this popular dog type. While many people use “pitbull” as a catch-all term, there are actually several distinct breeds and bloodlines that fall under this umbrella. This guide will walk you through the official varieties, their characteristics, and what makes each one unique.
1. American Pit Bull Terrier
The American Pit Bull Terrier (APBT) is the only breed that everyone universally agrees is a Pit Bull – it’s in the name, after all!2 This medium-sized dog typically weighs between 35-60 pounds for males and 30-50 pounds for females, standing about 18-21 inches tall for males and 17-20 inches for females.10
With their muscular build and loyal temperament, APBTs form strong bonds with their families and are known for being affectionate companions. They require plenty of exercise and mental stimulation to channel their natural energy in positive ways.2
2. American Staffordshire Terrier
The American Staffordshire Terrier was technically the same breed as the American Pit Bull Terrier for decades. When the American Kennel Club decided to recognize the breed, they changed the name to separate it from its dogfighting history.2
These dogs are often mellow and friendly with proper socialization, though some may exhibit dog-on-dog aggression that can be mitigated through early training. They’re described as playful and good-natured, making them excellent companions for active households.2
3. Staffordshire Bull Terrier
The Staffordshire Bull Terrier is a British breed that developed from the dogs that weren’t exported to America. Smaller than their American cousins, these dogs were primarily kept as companion animals even when dogfighting was legal.2
Known for being extremely loyal and affectionate, Staffordshire Bull Terriers are a solid option for families with children. Their gentle nature and playful attitude make them great playmates for kids.2
4. American Bulldog
The American Bulldog descends from the English Bulldog and was primarily used as a working dog on farms in America. With their muscular build and devoted personality, these dogs are highly people-oriented and can suffer from separation anxiety.2
They make excellent family pets but require proper socialization and training due to their protective nature. Their larger size and energetic temperament mean supervision is important around small children.2
5. American Bully
The American Bully is a relatively new breed that first appeared around the 1980s. Recognized by the United Kennel Club but not the American Kennel Club, these dogs are more compact and muscular than other pitbull types.2
With their giant heads and “bully” appearance, they’re extremely athletic and require an active lifestyle. Despite their intimidating look, they’re bred for companionship rather than aggression.23
6. Colby Pitbull
The Colby Pitbull bloodline is one of America’s oldest and most popular, started by John Colby in 1889. This historic lineage features dogs with highly muscular builds, broad heads, and short tails.110
With over 100 years of history, Colby Pitbulls are known for their even temperament and make great family dogs. They do shed considerably, so regular grooming is necessary to keep them looking their best.1
7. Old Family Red Nose Pitbull
The Old Family Red Nose (OFRN) is an old strain originating in Ireland, known for their distinctive reddish coloration. These dogs typically have a copper-red nose and coat, red lips, red toe nails, and red or amber eyes.110
Originally bred for their “gameness,” this bloodline has been preserved by some of the most reputable breeders of the past. Not every red-nosed pitbull is a true OFRN – the dog must have a high percentage of recognized bloodlines in its pedigree.10
8. Razor’s Edge Pit Bull
Despite its intense name, the Razor’s Edge bloodline is known for being one of the best companion breeds of Pitbull. These dogs have a mild and calm temperament, making them excellent family pets.1
Physically, they feature a blocky muzzle with a broad chest and large bones despite their otherwise slim body. Their coarse coat should look sleek and shiny with proper care.1
9. Gottiline Pitbull
Gottiline Pitbulls are named for their sire, Juan Gotty, who sired over 1,000 puppies in his lifetime. These dogs are incredibly bulky and muscular with broad, square heads and a defined neck that blends seamlessly into the chest.1
Their powerful appearance belies their family-friendly nature when properly trained and socialized. Like all pitbull varieties, they thrive with consistent training and plenty of exercise.

FAQ About Pitbulls

Training Your Pitbull
Proper training is essential for any dog, but especially important for pitbull-type breeds. These intelligent, eager-to-please dogs respond well to positive reinforcement training methods. Early socialization and obedience training are key to raising a well-behaved pitbull that will be a great ambassador for the breed.15
- Start training early, as soon as your puppy has completed vaccinations
- Use positive reinforcement techniques
