Microchipping Your Pet: Why It Matters and What to Expect
Collar tags can fall off. Fences can fail. Disasters happen. A microchip is permanent identification that cannot be removed by weather, accident, or time — and it is the single most powerful tool for reuniting a lost pet with its family. According to a study published in the Journal of the American Veterinary Medical Association, microchipped dogs are returned to their owners at a rate more than twice that of non-chipped dogs. The technology is simple, the procedure is brief, and the failure rate is nearly zero — if the owner maintains registration.
| Step | Required Action |
|---|---|
| Get the chip | Vet implants chip, gives you the chip number |
| Register the number | Enter chip number + your contact info into a national registry (AAHA Universal Registry, HomeAgain, AKC Reunite, PetLink) |
| Verify the chip scans | Ask the vet to scan your pet before leaving |
| Update when you move | Log into your registry and update address and phone whenever they change |
| Check annually | Run a free lookup on AAHA's Universal Pet Microchip Lookup to confirm your registry is searchable |
The Registration Problem: Why Chips Fail
Approximately 58% of microchipped pets have incomplete, out-of-date, or non-existent registration (American Humane statistics). A chip with no registered owner cannot help reunite anyone. The chip is permanent; the registration is not automatic. When you adopt a pet, the chip registration may still be in the previous owner's or shelter's name — update it immediately. Use the AAHA Universal Pet Microchip Lookup (petmicrochiplookup.org) to check what database has your chip number, and verify the information is yours and current.
Frequently Asked Questions
How does a pet microchip work?
A microchip is a passive RFID device the size of a grain of rice, implanted under the skin between the shoulder blades. It contains a unique ID number. When a scanner is passed over the chip, it transmits the number, which links to the owner's contact information in a registry database.
Does microchipping hurt?
The injection is slightly larger than a standard vaccination needle but is similarly brief. Most pets show little to no reaction. It can be done at any age and typically takes less than 30 seconds.
If my pet has a chip, are they automatically findable?
Only if the chip is registered to current contact information in a searchable database. A chip without registration is unreadable. This is the most common failure point — check and update your registration annually.
