Permanent, lifelong identification is provided by a tiny chip approximately the size of a grain of rice, programmed with a unique unalterable code that is identified with a hand held scanner.
About 10 million pets get lost every year and do not have any proper ID. Without proper identification, 90% of lost pets never return home.
One-time placement of a microchip provides a way to identify pets in the event that they get lost and prevents them from becoming a heartbreaking statistic.
