Starting 1 December 2025, all dog breeders in NSW, whether regular, occasional, or accidental, must hold an active Breeder Identification Number (BIN). Cat breeders are not required to have a BIN, but they will automatically receive one if they use the NSW Pet Registry. New BINs issued after this date will cover both dogs and cats, while existing BINs will remain active for cats but inactive for dogs unless reactivated online.
For puppies born on or after 1 December 2025, advertisements must include the breeder’s BIN and the mother dog’s microchip number. Vets and identifiers will also need to record both details when microchipping litters. Applications for BINs can be made online via the NSW Pet Registry or offline through local councils, which require ID verification.
These changes form part of broader reforms under the Puppy Farming Act and updated animal welfare laws. Key rules include a cap of 20 adult female dogs per premises (up to 50 with an exemption), a lifetime limit of five litters per female (no more than three by caesarean), mandatory compliance with the Breeding Code of Practice, and minimum staffing ratios. Penalties for non-compliance are significant, with fines up to $110,000 and possible jail time for serious breaches.
