Companion animal legislation

NSW companion animal legislation details the identification and registration requirements for companion animals, and the duties and responsibilities of owners.

Companion Animals Act 1998

Companion Animals Regulation 2018

If you sell or give away a dog or cat

All dogs and cats advertised for sale (or given away) must have an identification number. This includes all advertisements - newspapers, posters, community notice boards and social media.

Under NSW Government regulations the identification number can be:

  • a microchip number
  • a breeder identification number
  • re-homing organisation number.

Any transfer ownership must be noted on the NSW Pet Registry within 14 days. The new owner must create a profile and ‘link’ their new pet at the time of collection.  If this is not done you must provide council with a Change of Owner/Details (C3A) form signed by you and the new owner.
