Banned Dog Breeds in the UK: Exemptions, Seizure and Penalties

Five types of dog are banned in the UK: the Pit Bull Terrier, Japanese Tosa, Dogo Argentino, Fila Brasileiro, and the XL Bully. The first four have been prohibited since the Dangerous Dogs Act 1991; the XL Bully was added across all four UK nations during 2024.¹² Owning one of these dogs without a Certificate of Exemption is a criminal offence. The maximum penalty in England and Wales is six months in prison and an unlimited fine, and the dog is seized and, unless a court grants exemption, destroyed.

Why “Type” Matters More Than Breed

The law does not ban named pedigree breeds. It targets dogs whose physical characteristics match a prohibited type: head measurements, body proportions, overall size, and general appearance. A dog with no known pit bull ancestry can still be classified as a pit bull type if it looks the part, and a crossbreed sharing a substantial number of traits with a banned type is treated as one.¹

This is where owners get caught out. There is no DNA test or pedigree certificate that settles the question. The assessment is visual, made by police, dog wardens, or an expert instructed by a court, and the burden of proving a dog is not a banned type falls on the owner. People who bought or adopted a dog they were told was a Staffie cross, or a bulldog mix, or something else entirely, can find themselves in court arguing over the shape of the dog’s skull.

What You Cannot Do With a Banned Dog

Regardless of which of the five types is involved, the following are criminal offences under the Dangerous Dogs Act:¹

Breeding a banned dog, or breeding from one.
Selling one, offering one for sale, or publishing an advertisement for one.
Giving one away or exchanging it.
Abandoning one, or allowing it to stray.

These prohibitions still apply if your dog is on the Index of Exempted Dogs. A Certificate of Exemption lets you keep the dog. It does not let you breed from it, sell it, or hand it to someone else.

Living Legally With a Banned Dog: The Certificate of Exemption

The Index of Exempted Dogs is the official register of banned-type dogs permitted to remain with their owners. In England and Wales it is managed by DEFRA.³ Scotland runs its own scheme through the Scottish Government, and Northern Ireland handles exemptions through local councils.

Staying on the register is a lifelong commitment. The conditions are:

The dog must be neutered and microchipped. Neutering deadlines apply, and the specifics depend on where you live and how old the dog was when the rules came in.⁴⁵
The dog must wear a muzzle and be kept on a lead in any public place, including inside a vehicle.
The owner must hold third-party liability insurance covering damage or injury caused by the dog.
The dog must be kept securely at the address on the certificate. It can only be kept elsewhere for up to 30 days in any 12-month period.
The registered keeper must be at least 16 years old.

Any breach invalidates the certificate. The moment the certificate is invalid you are in illegal possession of a banned dog, exposed to the same penalties as someone who never applied. Forgetting the muzzle, letting insurance lapse, missing a neutering deadline: each is enough on its own.

The Insurance Problem From July 2026

Third-party liability insurance is a legal requirement, but suitable policies have always been hard to find. When the XL Bully ban took effect, Dogs Trust extended its Companion Club membership to cover exempted dogs because no other insurer offered a suitable product. Dogs Trust has now announced it will remove third-party liability insurance from Companion Club from 1 July 2026, citing unsustainable costs.⁶

As of early 2026 it is unclear whether the government will step in with an alternative scheme, or whether a commercial insurer will fill the gap. Without cover, the certificate is invalid. If you hold an exemption, watch this closely. Losing insurance through no fault of your own still puts you on the wrong side of the law.

How a Dog Gets on the Index

For the four original banned types, you cannot simply apply. The process is triggered by the police or a council dog warden seizing a dog they believe is a banned type. A court then decides whether the dog is of a prohibited type and, if so, whether it poses a danger to public safety. The court looks at the dog’s temperament, its history, and whether the owner is fit to keep it.¹ If satisfied the dog is not dangerous, the court can place it on the Index and issue a Certificate of Exemption. If not, the dog is destroyed.⁷

The XL Bully route was different. Owners were given a window to apply directly for exemption before the ownership ban took effect: 1 February 2024 in England and Wales, 1 August 2024 in Scotland, and 1 January 2025 in Northern Ireland.⁴⁸⁵ Those windows have all closed. Anyone now found with an unregistered XL Bully faces prosecution, and a new application requires court authorisation.

If the registered keeper dies or becomes seriously ill, the dog does not automatically have to be destroyed. There are provisions to apply to a court for the exemption to be transferred to a new keeper, though the new keeper must be assessed. Scotland’s legislation specifically covers transfer on the death of the registered owner, a provision that was not originally part of the England and Wales rules.⁹

If Your Dog Is Seized

When a suspected banned dog is seized, it is placed in kennels while the authorities apply to a court. You are not allowed to visit.⁷

You then have two options. You can contest the classification in court and argue your dog is not a banned type. Or you can voluntarily surrender ownership, in which case the dog can be destroyed without a hearing. Nobody can force you to give up ownership, but contesting means your dog waits in kennels, sometimes for months.

If you already hold a valid Certificate of Exemption and the dog has not behaved dangerously, you should be able to get it back on producing the certificate and proof you have kept to the conditions. Where the court accepts a dog is a banned type but finds it safe, it can place the dog on the Index. Where the court finds the dog dangerous, it will be destroyed.

Penalties

In England and Wales, illegal possession of a banned dog carries up to six months in prison and an unlimited fine.¹ In Northern Ireland, the fine is capped at £5,000 alongside the same six-month prison term.⁵ Unless a court grants exemption, the dog is destroyed. The same penalty range applies to breeding, selling, giving away, or advertising a banned dog.

Any Dog Dangerously Out of Control

Separate from the breed-specific ban, Section 3 of the Dangerous Dogs Act applies to every dog of every type. If any dog is dangerously out of control in any place, public or private, the owner faces criminal charges.¹⁰ For owners of exempted banned-type dogs this carries a double risk: an incident can bring Section 3 charges and also lead the court to revoke the exemption and order the dog destroyed. Following every condition to the letter is not enough on its own if a single incident puts the dog’s behaviour in question.
