Dog and Cat Reforms

New laws for cat and dog owners come into effect on 1 July 2018

The laws and rules include:

  • Mandatory microchipping of cats and dogs
  • Desexing of dogs and cats born after the 1 July 2018
  • New rules for breeders who sell dogs and cats
  • Introduction of a statewide database, called Dogs and Cats Online.

These new laws will simplify dog registration process, make it easier to reunite lost dogs and cats with their owners, help identify and put a
stop to puppy farms and reduce euthanasia rates.

New laws - better outcomes

Following a long public consultation process, South Australia has new laws for the management of companion dogs and cats. The amended Dog and Cat Management Act 1995, and new Dog and Cat Management Regulations, represent the biggest change to the state's dog and cat laws in more than 20 years. The new laws also provide for much tighter management of cats. Cat owners can read more, at


These changes to the law are being phased in, which means some new laws are already in place, while others will not take effect until 1 July 2018.
