No Northern Ireland legislation prohibiting the sale of a puppy or kitten by someone other than its breeder has been identified. Dog breeding establishments are licensed by district councils, but the licensing regime does not restrict who may sell the animal on.
Proposed change — not yet law
DAERA consulted on new rules for the sale and supply of puppies and kittens between 2 June and 25 August 2025. On 18 February 2026 the Minister announced next steps: anyone selling or supplying a puppy or kitten would have to have bred it, and sellers of animals under six months old would have to register with their district council. The department said legislation was anticipated in autumn 2026.
