American bully XLs are now officially banned and government guidance has been published on rules for current owners.
From 1 February 2024 it will be a criminal offence to own one unless owners have successfully applied for it to be exempt in England and Wales.
There will be a longer deadline for owners to ensure the dogs are neutered and microchipped.
It follows a number of attacks involving the breed, although owners insist the dogs make lovable pets.
From 31 December 2023 it will be against the law to sell, abandon, breed from or give away an American bully XL, or have one in public without a lead or muzzle.
If your dog is less than one year old on 31 January 2024, it must be neutered by 31 December next year. If your dog is older than one year old on 31 January 2024, it must be neutered by 30 June.
