Keep your details up to date!
When you first get a dog, you need to make sure it's microchipped and registered. These are two separate processes, but you only need to do them once.
However, if your contact details change at any time - or if your dog goes to a new owner - it's very important that you update this information on the NSW Pet Registry.
You should also let your vet know about these changes, but that is a separate process to updating the Registry.
And if your dog has a tag with your phone number on it, make sure you update that too!
