Banned & Restricted Dog Breeds in the UK
The Dangerous Dogs Act 1991 prohibits certain breeds and sets strict rules for any dog declared dangerous. Here's what every UK owner — and prospective buyer — needs to know.
Last reviewed: May 2026
The Dangerous Dogs Act 1991
The DDA applies across England, Wales, Scotland and Northern Ireland. It bans specific breeds outright, allows any dog to be declared dangerous if out of control, and carries fines up to £20,000 plus imprisonment.
Enforcement is shared between local council dog control officers, the police (for serious incidents), trading standards (for breeders and sellers), and the courts (for prosecution).
Banned breeds
| Breed | Origin | Characteristics | Reason for ban |
|---|---|---|---|
| Pit Bull Terrier | United States | 25–35 kg, muscular, powerful jaw | Bred for fighting; strong bite force |
| Japanese Tosa | Japan | 36–61 kg, massive, strong-jawed | Bred for dog fighting |
| Dogo Argentino | Argentina | 40–45 kg, white coat, athletic | Bred for hunting/fighting |
| Fila Brasileiro | Brazil | 40–50 kg, large mastiff-type | Guard dog bred for aggression |
| XL Bully | United States | 18–23+ inches at shoulder | Added Dec 2023 after fatal attacks |
XL Bully — added December 2023
The American Bully (XL variant) was added on 1 December 2023 after a series of fatal attacks. Dogs registered before that date can remain under a grandfather clause with an exemption certificate. All new XL Bullies must be neutered or spayed and require exemption.
How breeds are identified
The law uses phenotypic identification (appearance), not DNA testing. Officers assess head shape, jaw structure, body proportion and muscular build against breed-standard photos. Mixed-breed dogs can be banned if they resemble a prohibited type. Identifications can be challenged in court.
Legal consequences
| Offense | Fine | Prison | Additional penalty |
|---|---|---|---|
| First offense (no exemption) | Up to £5,000 | Up to 6 months | Dog may be destroyed |
| Repeat offense | Up to £20,000 | Up to 14 years* | Dog will be destroyed |
| Breeding/selling banned breed | Up to £20,000 | Up to 14 years | Lifetime ownership ban possible |
| Failing to control | Up to £5,000 | Up to 6 months | Dog destroyed |
*Extended sentence if a death occurs. Additional consequences include a criminal record, dog confiscation and destruction, possible lifetime ban on ownership, strict civil liability for injuries, and kenneling costs (£30–50/day) while awaiting a court hearing.
Exemption certificates
An exemption certificate is a legal permission to keep a banned breed under strict conditions. It is not a free pass — non-compliance leads to revocation and destruction of the dog.
Eligibility
You may qualify if your dog was born before the breed's ban date, you can demonstrate it is not a danger to the public, and you have no dog-control convictions. New post-ban purchases generally do not qualify.

Challenging a breed identification
- Request a formal written assessment from the council.
- Gather evidence — vet certificate, DNA test, pedigree papers.
- Consult a solicitor specialising in dog law.
- Request a council review with your evidence.
- If unsuccessful, appeal to the magistrates' court (£200–1,000+ in legal fees, 3–6 months).
- A Kennel Club expert witness can provide testimony.
Regional variations
Scotland — same banned breeds; Control of Dogs (Scotland) Act adds local procedures.
Wales — identical to England; Welsh-language support available.
Northern Ireland — similar legislation, separate enforcement structure; contact your local council.
Republic of Ireland — separate Control of Dogs Acts; not covered by the UK DDA.
If you're caught
Whether the dog is found straying, reported by a third party, or involved in an incident, the council can seize it immediately. The owner is responsible for kenneling fees while the case proceeds. Dogs involved in bites or attacks are almost always destroyed — exemption is not available after a dangerous incident.

FAQ
Is there a DNA test to prove my dog isn't a banned breed? DNA tests exist but are not legally recognised by UK courts — phenotypic assessment is the legal standard.
Can I move abroad with my banned breed? Some countries allow it, others don't. Check destination laws first.
What if my new purchase turns out to be a banned breed? Contact a solicitor immediately — options are limited and exemption may not be available.
Can a banned breed be rehomed legally? Only with an exemption certificate and proper transfer of ownership registered with the council.
What if a banned dog attacks me? The owner is strictly liable. Report to police, pursue a civil claim, and seek compensation for medical costs and injuries.
