There are now new requirements for people wanting to sell or give away a dog or cat.
New advertising laws mean you must provide either a micro chip number, a recognised breeder identification number or a re - homing organisation number.
The aim of this is to give people more information about where they get their pets from and to encourage responsible breeding practices.
Kira Booth from the Wingecarribee Animal Shelter says the changes also apply to them.
