Th Kennel Club in the UK has posted information on a "New Dog Breeding Regulation". This relates to regulations from the
Department for Environment, Food & Rural Affairs (DEFRA) for breeding operations and related to members of The KC Assured Breeders Scheme.
"Changes to breeding regulations in England
New regulations on dog breeding in England will be live from 1st October. There are no changes to breeding regulations in Wales, Scotland and Northern Ireland. A number of significant changes are being made," which include requirements for a dog breeding licence. In addition, there is a defining of minimum welfare standards.
Alongside welfare, the breeder’s compliance history will also be assessed, to determine whether the breeder is either a low risk or high risk operator, i.e. whether it should be expected the breeder will maintain their standards for the duration of their licence period."
And DEFRA has a matrix to assess risk.
