Is the XL Bully banned everywhere in the UK?

The ban on owning an unregistered XL Bully applies across England and Wales, and Scotland introduced its own ban shortly after. Rules and dates have differed slightly by nation, so check the current GOV.UK guidance for where you live rather than assuming the same timeline applies everywhere.

Can my dog be classed as a banned type even if it's not that breed?

Yes. The law assesses a dog against a set of physical characteristics rather than checking its breed papers, so a crossbreed or a dog of uncertain parentage can be classed as a banned type if it matches those characteristics closely enough, regardless of what it was sold or registered as.

What happens if I already own a dog that turns out to be a banned type?

You need to go through the legal exemption process rather than simply keeping the dog as before. A court-granted exemption allows the dog to stay with you under strict conditions, including neutering, microchipping, insurance and being muzzled and leashed in public — trying to avoid the process is a criminal offence.

Do banned dogs have to be muzzled all the time?

An exempted dog must be muzzled and kept on a lead in any public place, which is one of the standing conditions of the exemption rather than a one-off requirement. This applies for the rest of the dog's life under the exemption, not just during an assessment period.

Banned dog breeds in the UK

Five dog types are currently banned from being owned in the UK without a court exemption: the Pit Bull Terrier, Japanese Tosa, Dogo Argentino, Fila Brasileiro, and, since February 2024, the XL Bully. The law bans dogs by physical type rather than by breed registration, so a dog can be classed as a banned type based on how it looks, whatever is written on its paperwork.

How the ban actually works

The Dangerous Dogs Act 1991 makes it a criminal offence to own, breed, sell, abandon or give away a banned type without a specific court exemption. Whether a dog counts as a banned type is decided against a set of physical characteristics, not a pedigree certificate or a breeder's description, which means the law can apply to a dog whose owner never intended to own a banned type at all.

This matters because it makes crossbreeds and dogs of unknown or mixed heritage just as subject to the ban as a dog sold under one of the named type names. If a dog is reported or comes to police attention and is assessed as matching the banned physical type closely enough, the legal process starts regardless of what the owner believed they had bought.

What an exemption involves

A court can grant an exemption allowing an existing banned-type dog to stay with its owner, but only under strict, ongoing conditions: the dog must be neutered, microchipped, covered by third-party insurance, and kept muzzled and on a lead in any public place. The owner also has to keep the dog securely so it cannot escape, and produce the exemption certificate on request.

Exemption is not automatic and is not available to a dog that has never been assessed and certified. Getting an assessment done properly, through the correct legal route, is the only way to keep a dog that turns out to match a banned type — trying to keep one unregistered is what turns an assessment into a prosecution.

What this means if you are choosing a dog

If you are considering a breed or type close to one of the banned five, or a crossbreed whose parentage is uncertain, it is worth checking the current GOV.UK guidance before you commit, since it sets out the physical characteristics used in an assessment far more precisely than a breed name ever could.

The ban is a legal status, not a judgement on temperament, and plenty of dogs who share physical traits with a banned type are unaffected because the assessment is specific. If you are ever unsure whether a dog you already own or are considering might be affected, GOV.UK's own guidance and a solicitor experienced in the area are the right places to check, rather than guessing from a breed label.
