The pet move: vet records, microchip updates, and the tag that gets your dog home

The most common cause of a permanently lost pet after a move isn't the pet getting out — it's the recovery infrastructure being attached to the wrong address. A neighbor finds the dog, takes it to a shelter, the shelter scans the chip, and the registry rings a phone number that doesn't work and an address that's eight states away.

Three records do this. None of them update automatically.

The microchip registry

Most pets are chipped, but the chip is just a serial number. The number resolves to a record in a registry — there are several (HomeAgain, AKC Reunite, 24PetWatch among the largest in the US). The registry is what holds your phone, email, and address. Moving doesn't update any of this.

1. Find the registry your chip is in. The vet who placed the chip will know; failing that, AAHA's universal lookup tool (petmicrochiplookup.org) will tell you.
2. Log in or create an account using the chip number and your email.
3. Update the address, primary phone, and secondary contact (often a parent or partner). Verify the email is one you actively check.
4. Test the lookup by entering the chip number on the registry's public lookup page; your contact info should appear correctly.

The vet's records

Even if you're keeping the same vet, their records show your old address. More commonly, you're switching vets entirely. Two parallel actions:

• At the old vet, request a transfer of records. Most clinics will email a PDF directly to the new vet within 1–2 business days.
• At the new vet, schedule a meet-and-greet visit even if no shots are due. The visit gets the pet a chart, gets you on the call list, and lets the new vet flag anything unusual the old chart didn't capture.

If the move crossed state lines, the rabies certificate may need to be re-issued in the new state's format, even if the vaccine itself is current. The new vet will know if it does.

The physical ID tag

The metal tag on the collar is the single most effective recovery tool, more so than the microchip. Most found pets are returned by the neighbor who reads the tag, not by the shelter. A current tag costs about $10 and arrives in a week.

Tag should have: pet's name, your phone number, and the city. Address is optional and many people skip it for privacy. The phone is what matters.

The cross-border move

If you're moving internationally — even to Canada or Mexico — the documentation requirements get more involved. Health certificates, parasite treatments, and breed-specific paperwork have country-specific rules and dated windows (most countries want a vet exam within 7–10 days of entry). Start the process at least a month out; some countries need 90+ days for the rabies titer test.

The thirty-minute checklist

Within the first weekend at the new address: update the registry online (5 minutes), order new tags (5 minutes), email the old vet to transfer records (10 minutes), schedule the meet-and-greet at the new vet (10 minutes). Done. The next time the pet gets out, the recovery path actually works.
