Details

If you own an XL Bully dog, you must provide Defra with evidence that your dog has been neutered for your Certificate of Exemption to remain valid. If you do not provide evidence that your dog has been neutered by the relevant deadline, your dog will no longer be exempt. 

Your XL Bully dog must be permanently neutered. Male dogs must be neutered through castration, and female dogs must be spayed.  An RCVS-registered veterinary surgeon must perform the neutering procedure.

Deadlines for providing evidence that your dog has been neutered

You must provide Defra with evidence that your XL Bully dog has been neutered on or before the relevant deadline. 

The owner and vet must fill in the veterinary confirmation of neutering form (VCN01) once the neutering procedure has been carried out. The owner should return the form to Defra.

The deadlines for neutering and the receipt of the form by Defra depend on the dog’s age on 31 January 2024.

Age of the dog on 31 January 2024 Deadline for receipt of form
12 months or older 26 July 2024 (but the dog must have been neutered by 30 June 2024)
At least 7 months old, but less than 12 months old 31 December 2024
Less than 7 months old 30 June 2025

Defra will contact the dog owner if there are any issues verifying the information on the form.

Defra recommends having your dog neutered as soon as possible so that you meet these deadlines.
