You've booked the flight, packed the carrier, and then the airline's website mentions a "health certificate issued within 10 days of travel." If you're reading this the week before a trip, that sentence alone can turn into a scramble for a same-week vet appointment.
Pet travel paperwork isn't one-size-fits-all — what you need depends on how you're traveling, where you're going, and how far in advance you plan. Here's what actually gets checked, and when.
The document that trips people up: the health certificate
Most airlines and many states require a Certificate of Veterinary Inspection (CVI) — sometimes just called a "health certificate" — signed by a licensed vet confirming your pet is healthy enough to travel and current on required vaccines.
What's required by travel type
| Travel type | Typically required | Timing |
|---|---|---|
| Domestic flight (in cabin or cargo) | Health certificate, proof of rabies vaccination | Certificate within 10 days of departure |
| Driving across state lines | Health certificate (required by many states), rabies proof | Varies by destination state, often 30 days |
| International travel | Health certificate, rabies titer test (some countries), microchip, import permit | Can require weeks to months of lead time |
| Hotel or short-term rental stays | Rabies proof, sometimes vaccination record | Varies by property |
Why the vaccine record matters as much as the certificate
The health certificate itself is only half the picture — the vet filling it out, or the airline/border agent reviewing it, is going to want to see the actual rabies vaccination date and expiration, not just take your word for it. If your pet's vaccine record is scattered across a vet portal login you haven't used in a year, a photo in your camera roll, and a paper card in a drawer, that's the moment it becomes a problem.
International travel needs even more lead time
If you're crossing a border, start checking requirements at least a month or two out — some countries require a rabies titer test (a blood test confirming vaccine effectiveness) that can take weeks to process, plus an import permit filed in advance. The USDA APHIS site is the standard reference for country-specific requirements, and it changes often enough that it's worth checking close to your trip date even if you checked before.
What to have ready before you book the vet visit for your certificate
- Current rabies vaccination date and expiration — the vet will need this to complete the certificate
- Full vaccination history — some airlines and destinations ask for more than just rabies
- Microchip number — required for most international travel and helpful for domestic flights too
- Your pet's weight and carrier dimensions — not a records issue, but worth confirming against airline pet policy before you're at the counter
None of this is complicated once it's organized — the friction comes from digging it up under a deadline. Having vaccination dates and vet contact info in one place means the certificate appointment is a quick confirmation instead of a research project.
