Have you ever lost a pet? It is a scary thought. A microchip can be inserted under the skin of your pet and can help reunite them with their lost family. These chips are relatively small and can be implanted during any routine exam or surgery. The microchips contain a 15 digit sequence, similar to a social security number, which identifies the pet. Most animal shelters and veterinary clinics in the country have scanners that can read the microchips and use that number to help locate the lost family.
