Dog breeders must be licensed by us if they:

  • breed 3 or more litters a year, unless they can show that none of the puppies have been sold
  • advertise dogs for sale and make more than £1,000 for the whole litter

If you think someone is breeding dogs illegally or running a puppy farm, or you have any concerns about the welfare of the dogs they’re breeding, report it to us.

We can check if they hold a licence with us and are complying with the law.

Before you start

You’ll need to provide:

  • your name, email address or phone number so that we can contact you for more information
  • any details you have about the breeder
  • your concerns and any evidence you might have to support this e.g. photos or advert links
