Microchipping & Registration


In NSW, all cats and dogs, other than exempt cats and dogs, must be microchipped by 12 weeks of age or before being sold or given away, whichever happens first. For this reason, microchipping is normally done at the time of first vaccination, however, it is never too late.

The microchip is implanted under the skin between the shoulder blades, and can be read by any veterinary clinic or council ranger with a microchip scanner. This then allows them to locate the owners of any found cats and dogs, by searching the Department of Local Government run database – the Companion Animal Registry.


Dogs are required to be registered by six months of age and cats by four months of age. The registration fee is a once-only payment, which covers the cat or dog for its lifetime in NSW, regardless of any changes in ownership.

You are encouraged to have your cat or dog desexed before registering it. Having your cat or dog desexed prior to registration helps to reduce straying, fighting and aggression and antisocial behaviour, such as spraying to mark territory. It also helps to reduce the number of unwanted pets born each year.

Discounted registration fees apply to desexed dogs.

Annual permits are now required for owners of non-desexed cats, restricted dog breeds, and dogs declared to be dangerous.

Registration fees are used by councils for providing animal management related services to the community. These may include ranger services, pound facilities, dog refuse bins, educational and other companion animal-related activities.


Your pet’s details can be update by filling out a ‘Change on Ownership’ form and handing it into council. These forms can be picked up from council or here at the clinic.

A new online service called the ‘NSW Pet Registry’ is also available if you would prefer to update your pet’s details online from the comfort of your home.

The NSW Pet Registry enables lost pets to be reunited with their owners and is now available for cat and dog owners to:

  • Create an owner profile
  • Update their contact details
  • Transfer ownership of pets
  • Report their pet missing
  • Pay most lifetime registration fees online
