You must register your petâs microchip to give your pet the best protection. Register your petâs microchip in a national pet recovery database such as HomeAgain with your contact information, so you can be contacted when your lost pet is found.
Each microchip has a unique number, which is entered in an international database. Veterinary hospitals, animal shelters and humane societies have microchip readers, scanners that can quickly be run over the dogâs shoulder blades, allowing the scanner to read your dogâs individual microchip number.
