What is a microchip?

About the size of a grain of rice, a microchip is implanted beneath your pet’s skin between the shoulder blades. It contains a unique number used to identify animals when scanned by a shelter or vet. The number is then used to find the owner’s contact information in a registry. A microchip is NOT a GPS or tracking device and it does not store contact information. A microchip must be registered to be functional.
