Banned Dog Breeds in the UK: The 5 Illegal Types, the XL Bully Rules and What Changes on 1 November 2026

How the XL Bully Exemption Scheme Works

The UK government has confirmed that five specific dog breeds remain illegal to own, breed, sell, or abandon under the Dangerous Dogs Act 1991. As of October 2026, the XL Bully type is subject to strict exemption rules requiring neutering, microchipping, and third-party liability insurance for legal ownership. More than 57,000 XL Bullies have already been registered for exemption in England and Wales, indicating widespread owner compliance ahead of the November 2026 deadline.

The banned breeds include the Pit Bull Terrier, Japanese Tosa, Dogo Argentino, Fila Brasileiro, and XL Bully. Ownership of these types without a valid exemption certificate is a criminal offence punishable by an unlimited fine, up to six months in prison, and potential destruction of the dog. The XL Bully was added to the list in 2023 following a rise in serious incidents, prompting the government to introduce a managed exemption scheme rather than an outright ban.

What Happens If You Own a Banned Breed Unknowingly?

To legally keep an XL Bully after 1 November 2026, owners must have applied for exemption before the deadline, ensuring their dog is neutered, microchipped, and kept on a lead and muzzled in public. Veterinary confirmation of neutering and proof of insurance are mandatory. Local authorities conduct checks, and failure to comply risks seizure of the animal. The scheme aims to balance public safety with animal welfare, allowing responsible owners to retain their pets under strict conditions.

Many owners may not realise their dog falls under the banned XL Bully type due to variations in appearance or mixed heritage. Authorities assess dogs based on physical characteristics, not breed labels or pedigree. If a dog is suspected of being a banned type, it can be seized by police or local council officials while an assessment is carried out. Owners are advised to seek veterinary or expert guidance if uncertain about their dog’s status, as ignorance of the law is not a defence.

What defines an XL Bully under the law? An XL Bully is identified by specific physical traits including height, weight, and head shape, assessed against government guidelines rather than breed registration.

Frequently Asked Questions

Can I still walk my exempt XL Bully in public? Yes, but it must be muzzled and on a lead at all times in public spaces, and you must carry proof of exemption and insurance.

What should I do if I think my dog might be a banned type? Contact your local authority or a veterinarian for an assessment; do not delay, as keeping an unexempt banned dog is illegal regardless of intent.
