15 Dogs That Look Like Pitbulls, Big and Small
Dog Breeds
A stranger crosses the street when a Boxer mix trots past. A rental form asks, in bold type, whether the dog is a pit bull. Plenty of dogs that look like pitbulls are something else entirely, and the mix-up follows them everywhere, from the dog park to the leasing office.
The resemblance usually comes from shared family history. Bulldogs and terriers were crossed in nineteenth-century Britain, and their descendants spread into dozens of breeds with the same broad head and muscled chest. Many of the old fears attached to that look don't hold up, as these pit bull myths worth letting go of explain.
Pit Bull Type Dogs vs the American Pit Bull Terrier
"Pit bull" describes a type of dog, not one breed. The label usually covers the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier and American Bully, plus mixes of them. Breeds that look similar but sit outside that group include the American Bulldog, Boxer, Bull Terrier, Dogo Argentino, Cane Corso and Presa Canario. They share a wide skull, strong jaw, deep chest and short coat, but differ in size and temperament.
Breeds Grouped Under the Pit Bull Label
The American Pit Bull Terrier is the dog most people have in mind: 30 to 60 pounds, 17 to 21 inches at the shoulder, with a short coat in almost any color. Beyond that, kennel clubs disagree. The United Kennel Club registers the American Pit Bull Terrier and the American Bully, while other registries recognize the AmStaff and the Staffy but not the APBT.
Why Pit Bull Lookalikes Get Mislabeled
In a University of Florida study, 16 experienced shelter workers, veterinarians among them, judged the breeds of 120 dogs that were then DNA tested. Dogs with pit bull heritage were picked out only 33 to 75 percent of the time, depending on who was looking. About one in three dogs with no pit bull DNA at all got the label from at least one assessor.
Genes don't blend evenly, either. A Lab and Boxer cross can inherit the blocky head and little else, which is why this look at what makes a dog a mutt explains how often shelter cards and DNA results disagree.
Small Pit Bull Lookalike Breeds Under 40 Pounds
For the pit bull face in a lap-sized dog, these four come closest.
Staffordshire Bull Terrier
The Staffy is the dog most often mistaken for a pit bull, since both come from the same bull and terrier ancestors. It is shorter and stockier, with a wide grin, cheek muscles that bulge when it pants and a tail that wags its whole back end.
Staffies rank among the most popular dog breeds in Australia, especially in Western Australia, where a well-socialized one is a clownish, devoted family dog.
- Size: 14 to 16 inches, 24 to 38 pounds
- Lifespan: 12 to 14 years
- Best for: families who want a people-focused dog in a compact size
- Notable trait: can be choosy about other dogs, so early socialization matters
Miniature Bull Terrier
Shrink a Bull Terrier to knee height, keep the egg-shaped head and small triangular eyes, and that's the Mini. From the neck down it is as muscled as any pit bull. The face gives it away.
- Size: 10 to 14 inches, 18 to 28 pounds
- Lifespan: 11 to 14 years
- Best for: apartments and owners with patience and a sense of humor
- Notable trait: stubborn, so short and upbeat training sessions work best
Patterdale Terrier
A working terrier from England's Lake District, the Patterdale has a broad head, compact muscle and a short black, red or chocolate coat that reads as "mini pit bull" to most passersby. It was bred to follow foxes underground, and it hasn't forgotten the job.
- Size: 10 to 15 inches, about 11 to 13 pounds
- Lifespan: 11 to 14 years
- Best for: active owners who enjoy a busy, bold little dog
- Notable trait: very high prey drive around cats and small pets
Boston Terrier
Bostons descend from a Bulldog and white terrier cross, close to the recipe behind the early pit bull types, which explains the square head and sturdy frame. The short muzzle and tuxedo markings set them apart. They get confused with Frenchies just as often, and this French Bulldog vs Boston Terrier comparison shows how to tell those two apart.
- Size: 15 to 17 inches, up to 25 pounds
- Lifespan: 11 to 13 years
- Best for: city living and first-time owners
- Notable trait: flat face, so heat and hard exercise need care
Medium Breeds Mistaken for Pit Bulls
These dogs sit in the same 40 to 80 pound range as a typical pit bull, and a couple are pit bull types in all but name.
American Staffordshire Terrier
The AmStaff and the American Pit Bull Terrier began as the same dogs. Show breeders took one name, working lines kept the other, and decades apart have changed them only a little. AmStaffs tend to be slightly shorter, heavier through the chest and more uniform in head shape.
Like Staffies, many adore people and are less sure about other dogs. If an AmStaff starts lunging on leash, this guide to training a reactive dog walks through the distance work step by step.
- Size: 17 to 19 inches, 40 to 70 pounds
- Lifespan: 12 to 16 years
- Best for: experienced owners who enjoy training
- Notable trait: athletic and strong, with a huge appetite for play
American Bully
Developed from the American Pit Bull Terrier with some bulldog added, the American Bully exaggerates every pit bull feature: wider chest, heavier bone, shorter and blockier head. It comes in pocket, standard, classic and XL sizes, so one Bully can be knee-high and another as heavy as a mastiff. Owning an XL now requires an exemption certificate in England and Wales. Even a pocket Bully pulls hard, so a front-clip style from this guide to choosing a dog harness makes walks far easier.
- Size: 13 to 23 inches, 25 to 120 pounds across the four sizes
- Lifespan: 10 to 12 years
- Best for: owners who want a calm, people-loving companion
- Notable trait: heavy builds tire quickly in hot weather
Bull Terrier
The Bull Terrier has the pit bull's muscle and short coat, but the head is its own thing: long and smoothly curved, with no dip between forehead and nose, and small triangular eyes set high.
- Size: 21 to 22 inches, 50 to 70 pounds
- Lifespan: 12 to 13 years
- Best for: playful homes where someone is around most of the day
- Notable trait: may chase its tail compulsively when bored
Olde English Bulldogge
A modern recreation of the old working bulldog, the Olde English Bulldogge was bred from English Bulldog, Bullmastiff, American Bulldog and American Pit Bull Terrier. That last ingredient shows. The body is close to pure pit bull, while the head is wider, with a shorter muzzle and a slight underbite.
The shorter muzzle puts it closer to the breeds that suffer in summer than to the dogs that handle hot weather well, so walks belong early or late on warm days.
- Size: 17 to 20 inches, 50 to 80 pounds
- Lifespan: 9 to 14 years
- Best for: families who want a sturdy, less extreme bulldog
- Notable trait: calm indoors, but a strong puller on leash
Boxer
Boxers share the square jaw, short coat and fawn or brindle colors of many pit bulls, which is why so many Boxer mixes get labeled pit bulls at intake. The tell is the face. A Boxer's muzzle is shorter and blunter, with an underbite and a wrinkled, quizzical forehead.
Bouncy, silly and devoted, the Boxer earns its place among the best family dogs for active homes.
- Size: 21.5 to 25 inches, 50 to 80 pounds
- Lifespan: 10 to 12 years
- Best for: active families with older children
- Notable trait: greets people by jumping up, so polite hellos need early training
Large Breeds With a Pit Bull Build
The bigger lookalikes are mostly bulldog and mastiff types, often two or three times a pit bull's weight, and several were bred as guardians.
American Bulldog
Mostly white with brindle, red or black patches, the American Bulldog looks like a pit bull that kept growing. Working lines are leaner and more athletic, while bully lines carry heavier heads and shorter muzzles. Both are farm dogs at heart, bred to catch hogs and guard property.
- Size: 20 to 28 inches, 60 to 100 pounds
- Lifespan: 10 to 12 years
- Best for: active, experienced owners with room to roam
- Notable trait: a natural guarding instinct
Dogo Argentino
The Dogo is the dog most often called a white pit bull. Developed in Argentina to hunt boar and puma, it has an all-white coat, sometimes with one dark patch near an eye. It is far bigger than a pit bull, though, and white-coated dogs carry a higher risk of deafness, so ask any breeder about hearing tests.
- Size: 24 to 27 inches, 80 to 100 pounds
- Lifespan: 9 to 15 years
- Best for: experienced handlers with secure fencing
- Notable trait: intense prey drive
Cane Corso
The Italian mastiff is lean for its size, with a short glossy coat in black, gray, fawn or brindle. Natural ears hang in soft triangles. Cropped, the Corso looks remarkably like an oversized pit bull. It is quiet at home and serious about strangers, one of the big dog breeds best kept by people who have owned a guardian before.
- Size: 23.5 to 27.5 inches, 88 to 110 pounds
- Lifespan: 9 to 12 years
- Best for: experienced owners who want a protective dog
- Notable trait: needs socialization that continues for life
Presa Canario
Bred in the Canary Islands to guard farms and drive cattle, the Presa has a thick, square head, a dark mask and a body slightly longer than it is tall. It is a capable guardian, wary of strangers, and not a first dog for anyone.
- Size: 22 to 26 inches, 85 to 130 pounds
- Lifespan: 9 to 11 years
- Best for: experienced owners only
- Notable trait: strongly territorial
Bullmastiff
English gamekeepers crossed Bulldogs with Mastiffs to stop poachers, and the result is a heavyweight who is gentle at home. The wrinkled forehead and dark muzzle look more mastiff than pit bull, but a fawn Bullmastiff seen side-on has the same deep chest and short back.
- Size: 24 to 27 inches, 100 to 130 pounds
- Lifespan: 7 to 9 years
- Best for: calm homes with floor space to spare
- Notable trait: drools and snores generously
Boerboel
South Africa's farm guardian is the heaviest dog here, a mastiff that can pass 150 pounds and still move with surprising agility. The blocky head and short tawny or brindle coat recall a pit bull drawn at giant scale.
- Size: 22 to 27 inches, 150 to 200 pounds
- Lifespan: 9 to 11 years
- Best for: experienced owners on rural properties
- Notable trait: deeply protective of family and territory
How to Tell a Pit Bull From a Lookalike
No checklist is foolproof with mixes, but a few clues help.
Pit Bull Head Shape, Muzzle and Ears
A pit bull's head is broad and wedge-shaped, with a medium-length muzzle and a clear stop where the forehead meets the nose. Boxers, Bulldogs and Bostons have shorter, flatter muzzles. Bull Terriers have no stop at all. Mastiffs carry looser skin, deeper wrinkles and a lot more drool.
Pit Bull Size, Weight and Coat Color
Most American Pit Bull Terriers weigh 30 to 60 pounds. A dog well over 80 pounds is far more likely to be a bulldog or mastiff type, and an all-white giant is probably a Dogo. Pit bulls come in nearly every color, so the coat tells less than people expect.
When a Dog DNA Test Settles It
For a mixed dog, a DNA test is the only reliable way to know what's in the family tree. It won't predict temperament, but it is useful paperwork where the law cares what a dog looks like.
Breed Laws That Catch Pit Bull Lookalikes
Looks matter most once the law is involved. Australia bans the import of five breeds, among them the American Pit Bull Terrier, the Dogo Argentino and the Presa Canario, and states and councils add their own rules for restricted dogs. In Canada, Ontario's Dog Owners' Liability Act defines a pit bull to include Staffordshire Bull Terriers, American Staffordshire Terriers and dogs that look substantially similar, and it leaves the owner to prove a dog is not one.
Leases, strata bylaws and home insurance policies often use the same loose wording, so check them before adopting a bully-type mix.
Living With a Bully Breed or Mastiff Type
Exercise and Leash Training for Strong Dogs
Nearly every dog on this list is stronger than it looks. Daily exercise, sturdy chews and loose-leash training from puppyhood save a lot of sore shoulders.
Socializing Bull Breeds With Dogs and Kids
Many bull and terrier breeds love people and feel less sure about other dogs, while guardian breeds can be cool with strangers. Socialization starts in puppyhood and never really ends. With children, supervision matters for every breed, and these tips on helping dogs and kids get along cover the quiet warning signs to watch for.
Adopting a Pit Bull Mix From a Shelter
Big, blocky dogs wait longest in many shelters, often because of a label they may not deserve. Meet the dog more than once and judge the individual, not the face. This honest answer to whether to get a rescue dog covers what to ask before signing anything.
Before the meet and greet, the University of Florida's summary of how unreliable visual pit bull identification is is a short, useful read.
