Having your pet microchipped is an easy procedure. A tiny chip that is roughly the size of a grain of rice is injected under your pet’s skin between their shoulder blades using a needle. The chip has a number which you then use to register your information in a database. When you register the chip, you provide your contact information, such as your pet’s name and your phone number. This information is not stored on the chip itself, but rather in the account you create. When the chip is scanned at an animal shelter, it brings up the registration number, which is linked to your account.
