Microchips for Dogs and Cats: What Owners Should Know
A microchip is permanent identification placed under the skin, but it only works when the registration is current. It is not GPS and does not track your pet's location. Ask your veterinarian or shelter to scan the chip and confirm the registry information after any move or phone-number change.
What symptoms or causes should I watch for?
- Lost-pet identification: Shelters and clinics scan found pets for a microchip number.
- Registration gap: An unregistered chip may not connect the pet to an owner.
- Outdated contact details: Old phone numbers and addresses are a common failure point.
- Collar backup: A visible ID tag helps neighbors contact you before a shelter visit.
- Travel and disasters: Microchips help during moves, storms, fires, and accidental escapes.
What can I safely do at home right now?
- Scan the chip: Ask a clinic or shelter to confirm the chip number reads correctly.
- Register it: Use the registry linked to the chip and add all current contact details.
- Add backup contacts: Include another trusted person if the registry allows it.
- Update after moves: Change phone numbers, email, and address immediately after any change.
- Keep collar ID: Use a tag as a visible first line of identification.
When is this an emergency?
Go to an emergency veterinary clinic now if you notice:
- Your pet is lost and the chip is not registered.
- A found pet has no readable chip or collar identification.
- A registry lists an old owner, phone number, or address.
- A newly adopted pet has a chip that was never transferred.
- Travel, disaster evacuation, or escape risk without current ID.
What will my veterinarian check?
Your veterinarian or shelter can scan for a chip, confirm placement, implant one when appropriate, and help you understand registration steps.
How can I reduce the risk next time?
Check chip registration yearly, after every move, and after adoption transfer.
