9 Banned Dog Breeds to Avoid as Pets
Owning a dog can bring immense joy and companionship, but it’s worth knowing that certain breeds are banned or restricted in various regions due to safety concerns. While many of these breeds are loyal and loving in the right hands, their physical power and, in some cases, history of being bred for fighting or guarding have led lawmakers to regulate them.
Below is a guide to breeds that face bans or restrictions somewhere in the world, along with the reasoning behind it. Breed-specific legislation (BSL) varies enormously by country, and even by state, province, or city within a country — and it changes over time. Treat the regional notes here as a starting point, not a legal reference, and always confirm current rules with your local council, city, or state before acquiring one of these breeds.
Why Some Breeds Are in the Doghouse
Breed-specific legislation is typically introduced to reduce risk associated with breeds that have historically been bred for fighting or guarding. These laws regulate breeds based on perceived risk rather than an individual dog’s actual temperament, which means a calm, well-socialized dog can still be restricted purely because of its breed.
Key reasons bans exist:
- Public safety: reducing the odds of serious injury in worst-case scenarios.
- Historical use: breeds developed for fighting or guarding carry that reputation into legislation, fairly or not.
- Mismanagement: irresponsible ownership and poor training create real incidents that reinforce breed stereotypes for everyone else.
Whether BSL actually reduces dog bites is genuinely disputed — several veterinary and animal-behavior organizations argue that owner behavior and individual temperament matter far more than breed alone. That debate doesn’t change the legal reality for owners, though: if a breed is restricted where you live, that applies regardless of your own dog’s personality.
9 Banned or Restricted Dog Breeds
1. Pit Bull Terrier
One of the most widely restricted breeds worldwide. Pit bull-type dogs are muscular, athletic, and were historically bred for dog fighting, which shaped their controversial reputation despite many individuals being affectionate family companions.
Why they’re restricted: strong bite force and physical power, historical association with fighting, and high-profile attack incidents that raised public concern.
Regions with restrictions: the UK (under the Dangerous Dogs Act), specific Canadian provinces, and parts of Australia — rules and enforcement vary widely even within these.
2. Japanese Tosa
A rare, large mastiff-type breed developed in Japan specifically for dog fighting. Their size and combat history make them one of the most heavily regulated breeds internationally.
Why they’re restricted: bred for combat, requiring very experienced handling, plus a large, muscular build that poses real physical risk if a dog becomes aggressive.
Regions with restrictions: UK, New Zealand, and Denmark.
3. Dogo Argentino
A large white hunting breed developed in Argentina for big-game hunting (including wild boar). Loyal and protective with their family, but bred with a strong prey drive and physical power.
Why they’re restricted: hunting instincts and strength can translate to real risk if the dog isn’t properly trained and socialized.
Regions with restrictions: UK, Australia, and parts of the United States.
4. Fila Brasileiro
Also known as the Brazilian Mastiff, this large guardian breed is known for near-total loyalty to its family and instinctive distrust of strangers — a trait actually written into some breed standards.
Why they’re restricted: intense guarding instincts and wariness of unfamiliar people, which requires an experienced owner to manage safely.
Regions with restrictions: UK, Norway, and New Zealand.
5. Presa Canario
Originating in the Canary Islands, the Presa Canario is a powerful working breed originally used for guarding livestock. Loyal and confident, but strength and a protective streak have led to restrictions in some places.
Why they’re restricted: originally bred for guarding and, historically, fighting; high potential for aggression if undertrained.
Regions with restrictions: Australia, New Zealand, and parts of the United States.
6. Wolfdog Breeds (e.g., Czechoslovakian Wolfdog)
Wolfdog hybrids are crosses between domestic dogs and wolves. Fascinating and striking, but their wild ancestry can make behavior less predictable than a fully domesticated breed.
Why they’re restricted: less predictable behavior tied to wild ancestry, and potential risk around small animals or young children.
Regions with restrictions: Norway, UK, and several US states (some ban wolf-dog hybrids outright, others require permits).
7. Boerboel
Also known as the South African Mastiff, the Boerboel is a powerful, protective breed originally developed to guard farms. Its size and territorial instincts have led to regulation in some regions.
Why they’re restricted: highly territorial and protective by breeding, requiring firm, consistent training and early socialization.
Regions with restrictions: Denmark, Romania, and Singapore.
8. American Bulldog
Not banned everywhere, but restricted in some areas due to its muscular build and guarding instincts inherited from its farm-dog and working-dog ancestry.
Why they’re restricted: physical power combined with guarding instincts, plus incidents tied to inexperienced or irresponsible ownership.
Regions with restrictions: specific local authorities in the UK and Australia.
9. Cane Corso
A large Italian mastiff bred for guarding property and livestock. Calm and loyal with proper training, but its size, strength, and intimidating presence have led some jurisdictions to regulate ownership.
Why they’re restricted: protective instincts that can tip into aggression without proper handling, and an imposing appearance that shapes public perception.
Regions with restrictions: a small number of local authorities in Germany, specific Canadian provinces, and some US municipalities.
Paws and Responsibility: Why Ownership Matters
While these breeds face bans or restrictions somewhere, behavior overwhelmingly depends on training, socialization, and responsible ownership. Many of these dogs thrive with experienced, dedicated owners.
- Start early: training and socialization in the first year make the biggest long-term difference in behavior.
- Understand the breed: each of these breeds has real physical and mental exercise needs — research them thoroughly before bringing one home.
- Advocate for education over stereotypes: responsible-ownership conversations do more for public safety than blanket breed bans, according to many veterinary behaviorists.
Frequently Asked Questions
Is it illegal to own a pit bull?
It depends entirely on where you live. Some countries and cities restrict or ban pit bull-type dogs outright; many others have no restrictions at all. Always check your specific city, county, or country’s current animal control ordinances rather than assuming based on general reputation.
What exactly is breed-specific legislation (BSL)?
BSL is any law that regulates, restricts, or bans dog ownership based on breed or physical type rather than an individual dog’s behavior. It can range from an outright ban to requirements like mandatory muzzling, liability insurance, secure fencing, or neutering.
Can I get homeowners or renters insurance if I own a restricted breed?
Often, yes, but many insurers maintain their own breed exclusion lists separate from local law, and some will charge higher premiums or deny coverage for certain breeds. Check with your specific insurer before bringing a restricted breed home — don’t assume legal ownership means automatic insurance coverage.
Are banned breeds actually more dangerous than other dogs?
This is genuinely debated. Bite statistics are heavily influenced by reporting bias, breed misidentification, and owner behavior, and several major veterinary and animal-behavior organizations have argued that BSL doesn’t reliably reduce dog bite incidents. What’s well established is that training, socialization, and responsible management matter enormously regardless of breed.
Do these laws change often?
Yes — BSL is amended, repealed, and introduced regularly as public opinion and incident data shift. The UK, for example, added the XL Bully to its restricted list in 2023-2024 after previously not regulating it. Never rely on older articles (including this one) as a final legal answer — check your current local ordinance directly.
Wrapping It Up: A Tail-Wagging Decision
Understanding the reasoning behind breed bans helps you make an informed decision when choosing a pet — and helps you avoid the heartbreak of falling for a dog you later can’t legally keep where you live. If you’re considering any of the breeds above, research current local regulations first, then make sure the breed’s energy level, size, and temperament genuinely fit your home and experience.
Choose a breed that fits your lifestyle, and prioritize training, socialization, and proper care no matter which breed you bring home.
