If you move address or change your contact details, make sure you update your pets' entry on the pet registry.
If your new puppy was microchipped by the breeder, you will need to change the puppy into your name. This can be done by contacting the microchipping company which the microchip is registered with online. Once the microchip is in your name, the puppy is legally yours!
If a pet is ever lost and is handed in at a veterinary clinic or animal shelter a microchip scanner is passed over the animal to reveal the unique code. The vet or animal shelter can then refer to the database to identify the name, address and phone number of the owner, so they can be reunited.
