I wanted to share this story because I now think it is a very good idea for a pet to have both a microchip and a tag with a phone number to call in order to increase the chance of your pet being returned safely.
Concerning the microchip, there are three things to do to ensure that it remains able to help reunite you with your pet:
1. Have your vet check the microchip occasionally to verify it is still electronically readable. Most pet microchips are estimated to remain functional for 12 to 20 years, but some pets have lived longer than their microchip remained functional or the microchip simply quits working.
2. Check yearly to confirm that the company that your pet’s microchip is registered with is still in business. A shelter or animal control agency would use the ID number read out of the microchip to contact that company, who will then connect you with whoever found your pet.
3. Make sure the information you have registered is up to date. Phone numbers and emails change, households move.
