Microchips are an important permanent method of identification for your pet. Collars and tags can come off or become lost. The microchip is placed under the skin in the shoulder area. This can be done at any time, even during a routine appointment. If you pet is lost, veterinary clinics, police stations, dog wardens and humane societies/shelters are equipped to read the microchips and will attempt to locate you based on the information registered.
