A microchip is a tiny memory chip, no larger than a grain of rice, with some very important data recorded on it. This includes a unique ID number, along with the contact information for a pet registry service. When you have the microchip implanted, you will also register your pet with the service. You can update your information with the registry at any time, such as when you change phone numbers or addresses.

If your pet goes missing all shelters and veterinary clinics can simply use a scanner to see if your pet has been microchipped. The shelter staff will submit the chip information to the animal registry service, which will respond by telling them how to reach you and tell you that your pet has been found.

As you can see, microchipping can prove tremendously valuable in reuniting you with your pet -- possibly even saving him from being euthanized at an overcrowded shelter. Take a simple step that can make all the difference between a tragic loss and a joyous reunion.
