If your pet goes missing, you want him or her returned home as soon as possible. A microchip is a simple, effective way to ensure your pet returns home safely. Identification microchips are about the size and shape of a grain of rice. Microchips are implanted beneath your pet's skin, usually between the shoulder blades. Each microchip is encoded with unique information about your pet; this information is stored in a national database. Veterinary hospitals and animal shelters across the country are equipped with special scanners capable of reading these microchips. If your pet is lost, the microchip is scanned and the information is used to reunite you and your pet
