Breeders - Kennel Club Registered Puppies

Breeders in England, Scotland and Wales must ensure puppies are microchipped and registered with an approved microchip database by the time the puppies are 8 weeks old (prior to going to the new owner).

What does this mean for you?

  • The breeder must always be the first registered keeper on the database.
  • No breeder or dog owner may transfer a dog to a new owner until it has been microchipped, unless a certificate from a veterinary surgeon has been issued regarding the dog’s health. For more information on the veterinary certificate visit the FAQs page.
  • When a dog is transferred to a new owner, the new owner must, unless the breeder had already done so, record their contact details on an approved microchip database to ensure they comply with the law.
  • Breeders should make it as easy as possible for new owners to be able to access the microchip database to ensure their contact details are kept up to date.
  • All breeders must ensure that they can clearly identify that the microchipping paperwork matches the puppy being sold to the new owner.

When a pet is microchipped, the unique code for the microchip will be registered on a database. This includes the microchip details, information on the pet and contact information for the owner.

This allows owners to ensure their contact details and records are kept up to date and the database will provide a lost and found service in the event a pet goes missing.

If a dog becomes lost or stolen, the microchip can be scanned and matched to the owner’s contact details, which are kept on the database.
