Microchipping and sterilising cats and dogs


All newly registered cats and dogs must be microchipped. Pets previously registered with another Council must also be microchipped before applying for registration in the City of Maribyrnong.

Microchipping is the simple and painless process of injecting a silicon chip, the size of a grain of rice, under the skin and between the shoulder blades of your pet. Microchipping significantly increases your chances of being reunited with a lost pet. Each microchip contains a 15 digit number that corresponds with the owner's contact details. These details are stored on one of five microchip databases.

The National Pet Register

National Pet Register is Australia's largest not-for-profit pet identification service, operated and run by The Lost Dogs' Home. National Pet Register reunites over 23,000 lost pets with their owners every year. To ensure your pet has a speedy return home make sure it is microchipped by a National Pet Register agent.

Keep your details up-to-date

If your address or phone number changes, you need to update your details with the Central Animal Records. Please also ensure that you update your details on Council's Animal Registration database by contacting Customer Service.


Fertile cats and dogs are the cause of most pet nuisance problems. If you have your pet sterilised you can help solve the problem of unwanted pets in society. Enquire with Council or your local vet for current costs for the procedure.
