Breeder responsibilities

Anyone breeding cats and dogs must ensure the health, safety and happiness of the pets in their care. The breeding essentials below are a starting point to help you meet legal requirements for breeders in NSW.

Breeder microchipping responsibilities

As a breeder, you must microchip cats or dogs before selling or giving them away, or by the time they are 12 weeks old. If you do not microchip them, you may be issued with a fixed penalty notice for $180 or a court may impose a maximum penalty of up to $880.

Before your microchipping appointment, create a litter on the NSW Pet Registry with details for all the puppies or kittens. Once you've booked an appointment, click the ‘Send for microchipping’ button on the ‘Litters’ page and enter your vet or authorised identifier’s email address. This lets them know they can now access these details using their NSW Pet Registry account.

Your vet or authorised identifier will receive an email about how to confirm litter details and enter microchip numbers for each animal online. Once they do this, you will receive a confirmation email and message on your NSW Pet Registry profile.

Many vets and authorised identifiers still use forms to identify animals on the NSW Pet Registry. They will microchip the litter, fill out the form and send it to council for processing.

This means you must wait much longer for microchipping to be confirmed via your NSW Pet Registry profile. You can encourage your vet or authorised identifier to use the more efficient digital system, but ultimately, the choice to use digital or forms is up to them.

Advertising pets in NSW

In NSW, when you advertise that you are selling or giving away kittens, cats, puppies or dogs, you must include an identification number.

This identification number can be the pets’ microchip number, recognised breeder number, or your breeder identification number (BIN), which is issued free of charge when you create a litter for the first time on the NSW Pet Registry. Rehoming organisations must use their rehoming organisation number.
