The concept of “dangerous dog breeds” is controversial, as behaviour depends on training, socialisation, and environment.
Some breeds, including the Pit Bull Terrier and Japanese Tosa, are banned under UK law.
Dog aggression is often linked to owner responsibility, poor training, and neglect rather than breed.
Understanding dog behaviour, early socialisation, and proper training reduces the risk of aggressive incidents.
Breed-specific legislation (BSL) is debated globally, with calls for responsible ownership laws instead.
The term “dangerous dog breeds” is widely debated. While some breeds have gained a reputation for aggression, experts agree that a dog’s behaviour is primarily shaped by training, socialisation, and environment rather than genetics alone.
In the UK, the Dangerous Dogs Act 1991 was introduced to ban certain breeds considered high-risk. However, animal welfare organisations, such as the RSPCA and The Kennel Club, argue that focusing on breed alone does little to prevent dog attacks and instead advocate for responsible pet ownership laws.
This guide will explore which breeds are legally restricted in the UK, debunk common myths surrounding so-called "dangerous" breeds, and discuss how responsible training and handling play a crucial role in preventing aggression.
A dangerous dog breed is typically defined as a breed with a reputation for aggression or attacks. However, breed alone does not determine a dog’s behaviour: environment, training, and socialisation play significant roles.
While some breeds require experienced handling, no breed is inherently aggressive. Proper training and socialisation from an early age play the most critical role in shaping a dog’s temperament.
Bite Strength & Physical Capability: Large, muscular breeds with strong jaws can cause more severe injuries.
Historical Usage: Some breeds were originally bred for guarding or hunting, which contributes to their reputation.
Recorded Incidents: Certain breeds appear in dog bite statistics more frequently, but this often correlates with their popularity rather than their temperament.
In the UK, the Dangerous Dogs Act 1991 bans or restricts the ownership of certain breeds. As of 2024, the following breeds are banned unless exempt:
Pit Bull Terrier – A breed historically used for dog fighting.
Japanese Tosa – A rare breed bred for fighting in Japan.
Dogo Argentino – A large hunting breed with strong protective instincts.
Fila Brasileiro – A Brazilian mastiff known for its guarding abilities.
XL Bully (as of February 2024) – Recently added due to concerns over attacks.
In response to a series of fatal attacks involving American XL Bully dogs, the UK government implemented a ban on the breed. Effective from 1 February 2024, it is illegal to own an XL Bully in England and Wales without a Certificate of Exemption.
Owners of exempted dogs must adhere to strict conditions, including neutering, microchipping, obtaining third-party insurance, and ensuring the dog is muzzled and on a lead in public.
In some countries, breeds like Rottweilers, Doberman Pinschers, and Akitas are restricted under dangerous dog laws, requiring specific ownership conditions.
Many "dangerous dog" labels are based on misconceptions rather than science. Here are some of the most common myths:
Reality: No breed is born aggressive. A dog’s behaviour is shaped by training, environment, and socialisation.
Breed-specific legislation (BSL) refers to laws targeting certain breeds based on perceived aggression risks.
Aims to reduce dog attacks.
Creates awareness of responsible ownership.
Discriminates against specific breeds rather than addressing real causes of aggression.
Leads to the unnecessary euthanasia of well-behaved dogs.
Focuses on breed rather than owner responsibility.
Most animal welfare organisations advocate for behaviour-based assessments rather than breed bans.
Regardless of breed, responsible pet ownership is key to preventing aggression.
Introduce dogs to various environments and people.
Use reward-based training rather than punishment.
Always supervise interactions between dogs and children.
Use proper leashes and enclosures in public spaces.
Regular health checks can identify medical conditions that may cause aggression.
Neutering may help reduce aggressive tendencies in some dogs.
Understand breed-specific needs before adopting.
Avoid using harsh training methods, as these can increase fear-based aggression.
While certain breeds are labelled as dangerous, no dog is born aggressive. Training, environment, and responsible ownership play the most crucial roles in shaping a dog’s behaviour.
Instead of focusing on breed bans, effective laws should promote education, responsible pet ownership, and stricter penalties for neglectful handling. If you are considering adopting a breed with a strong reputation, invest in proper training and socialisation to ensure a safe and well-behaved companion.

No breed is inherently dangerous, but breeds with strong physical traits, such as Pit Bulls and Rottweilers, require experienced handling.
Only with an exemption certificate proving responsible ownership and proper containment measures.
Research suggests BSL does not effectively reduce dog attacks . Stronger ownership laws and education are more effective solutions.
Not necessarily. Many banned breeds can be friendly and well-behaved with responsible training and socialisation.
