Rescue centres have revealed that hundreds of XL Bully dogs are set to be destroyed as a ban on the dogs approaches.

The new rules, which start from 31 December, will make it illegal to breed, sell, advertise, exchange, gift, rehome, abandon or allow the animals to stray in England and Wales.

The RSPCA, Blue Cross, and Battersea Dogs and Cats are among charities worried about the future of some of the dogs they are keeping.

They have warned at least 246 of the breed could be euthanised by the end of the year if a new home is not found for them.

The Blue Cross says it could cost as much as £90,000 for charities to destroy the dogs due to higher costs associated with their larger size.

The government has offered £200 to XL Bully owners to go towards the cost of euthanising their animals.

As the deadline for XL bully breeds registration approaches, a campaign group has taken legal action to delay the ban.

Here Yahoo News UK takes a look at the latest developments as XL Bully owners decide what to do next:

Applications opened for owners to register XL bully dogs

Owners who wish to keep their dogs must apply to an exemption scheme or they can choose to have their dog euthanised and apply for compensation.

Owning an XL bully from 1 February 2024 will be illegal unless the animal is on an exempt list, called the Index of Exempted Dogs.

Those who want to keep their dogs will have until the end of January to register them with the list and will then be forced to comply with strict requirements.

This will include the requirement to muzzle them and keep them on a lead in public, but the dogs must also be microchipped and neutered.

Dogs more than a year old on 31 January must be neutered by 30 June next year, while those under 12 months old must be neutered by 31 December 31 2024.

Owners without a certificate of exemption will face a criminal record and an unlimited fine if they are found to be in possession of an XL bully as of 1 February, and their dog could be seized.

Campaigners are trying to launch a judicial review

A campaign group of XL bully owners has raised over £160,000 to fund a potential judicial review to overturn the ban.

The Don't Ban Me - Licence Me organisation confirmed it had submitted a pre-action protocol to the UK government, instructed a lawyer and then hoped to submit an application to delay the new law by the next month.

The group’s head Sophie Coulthard told the Guardian: “We would like the government to consider licensing, because that is something that’s been presented to them, even through their own commissioned research, and has been ignored.

“There’s lots of really good models that are successful, where countries have just done away with breed specific legislation because what they found is they just kept banning more dog breeds and it clearly wasn’t working.

“It can involve mandatory training, making sure breeders are licensed properly, and stops people impulse buying dogs which you obviously see a lot.”

What is an American XL bully dog?

The American bully is a relatively new dog breed from the US, with its first official breed registry, the American Bully Kennel Club (ABKC), founded in 2004.

As it is not registered as a recognised breed by the UK Kennel Club, it is unclear how many of the dogs or breeders are currently in the country.

The UK government has estimated there are about 10,000 American XL bullies in the UK while the Blue Cross animal charity has suggested it is more like 15,000.

The breed comes in a variety of sizes, including pocket, standard and XL, the latter of which has become a cause of concern.

The breed is responsible for killing at least nine people, including three children, since 2001.
