Pet Transport to Thailand From the US: Import Permit, Vaccines, Airports and the Trip Home

Pet transport to Thailand from the US is one of the friendlier international moves. There is no long quarantine, no rabies titer for pets coming from the US, and no breed ban at the Thai border. What Thailand does have is a precise set of windows: an import permit you can apply for no earlier than 60 days and no later than 7 days before departure, a 21-day wait after primary vaccines, and a US health certificate that is valid for only 10 days from the day USDA endorses it. Line those up and the move is straightforward.

This guide follows the instructions published by the Office of Agricultural Affairs at the Royal Thai Embassy in Washington, which are the clearest primary source for US owners, and adds the practical parts: airports, airlines, costs, and how to prepare now for bringing your dog back to the US, because Thailand is on the CDC high-risk list for dog rabies. For moves to other countries, see our guide on how to relocate a pet internationally.

The rules at a glance

The Royal Thai Embassy's instructions for bringing dogs, cats and rabbits into Thailand from the USA, revised in January 2025, set out three stages: apply for an import permit, obtain a USDA-endorsed official health certificate, and present the documents to the Animal Quarantine Station when you land. The USDA page on pet travel from the United States to Thailand adds that pets must be at least four months old and points to the embassy's bringing pets to Thailand page for the forms.

Required vaccines and the 21-day rule

Thailand lists specific vaccines by species:

• Dogs: rabies, canine distemper, canine hepatitis, canine parvovirus and leptospirosis.
• Cats: rabies and feline panleukopenia.
• Rabbits: rabies, plus treatment for internal parasites at least 7 days before export.

Two timing rules sit behind that list. For a primary rabies vaccine, the pet must have been at least 12 weeks old when it was given. And after any primary vaccine, the animal must wait 21 days before you apply for the import permit. Boosters do not trigger the wait, but you must submit the earlier vaccination records to show continuity. If a dog has no valid leptospirosis vaccine, or cannot meet the 21-day rule for it, Thailand accepts a negative leptospirosis test taken within 30 days before departure instead.

Vaccination certificates must be in English and show the pet's breed, sex, date of birth, color and microchip number, plus the vet's full name, license number and signature. Most rejected applications fail on those details rather than on the vaccines themselves.

Step 1: apply for the import permit

The permit comes from Thailand's Department of Livestock Development through the Animal Quarantine Station at the airport where you will land. You email the application to that station at least 7 days and no more than 60 days before departure. The embassy recommends applying about 30 days ahead. Processing takes 5 to 7 Thai business days once the station has all documents, and the permit is valid for 60 days after it is issued.

The application includes:

• application form R1/1, with your name, your address in Thailand and the US, the pet's details, the microchip implantation certificate and your flight itinerary;
• a copy of your passport;
• a color photo of the pet with its face clearly visible; and
• the English vaccination certificates described above.

The embassy notes that owners travelling with their pet can apply on arrival at the quarantine station if they already hold the original USDA-endorsed health certificate and every other document. It also warns, in red, that some airlines require the Thai permit before boarding and may refuse the pet without it. Apply in advance.

Step 2: the official health certificate and USDA endorsement

Once the permit arrives, a USDA-accredited veterinarian completes and signs the official health certificate, and you submit it to USDA's Animal and Plant Health Inspection Service for endorsement. The certificate is valid for 10 days from the date of USDA endorsement, so the pet must arrive in Thailand within that window.

One detail matters more than any other here. The embassy instructions say only original certificates bearing the USDA stamp are accepted and that electronic copies are not valid. USDA can endorse many certificates electronically, so confirm with your vet and your USDA endorsement office that you will receive a physical, stamped original to carry. Our guide to pet health certificates for travel explains how endorsement works and its fees.

Step 3: arrival at the Animal Quarantine Station

Thailand designates quarantine stations at six airports: Suvarnabhumi and Don Mueang in Bangkok, Chiang Mai, Phuket, Samui, and Krabi, which is served by the Trang station. Pets must enter through one of them. On arrival, bring originals of your passport, the pet's vaccination records or pet passport, the endorsed health certificate and a printed copy of the permit. The station issues a notice of import approval and an import license, at a fee of 500 baht per animal. The license stays valid until the pet leaves Thailand, so keep it safe.

How the pet travels changes the timing. At Suvarnabhumi, the station for pets carried as baggage sits next to baggage carousel 8 and runs 24 hours a day. Pets shipped as air cargo are cleared at the cargo terminal, which keeps weekday office hours only and is closed at weekends and on Thai public holidays. A cargo pet that lands on a Friday evening may wait until Monday. Book cargo arrivals for a weekday morning.

Choosing your arrival airport

The import permit is issued by the quarantine station at the airport where the pet lands, so choose the airport before you apply. Bangkok's Suvarnabhumi is the main long-haul gateway and the station most agents deal with, and it handles both pets carried as baggage and pets shipped as cargo. Don Mueang serves mainly regional and low-cost flights. Chiang Mai, Phuket, Samui and Krabi are convenient if you are settling there, but fewer long-haul and cargo routes reach them directly, so many owners land in Bangkok and continue by road or a domestic flight once the pet has cleared. If your plans change after the permit is issued, contact the station that issued it; do not assume a permit for one airport covers another.

Cats moving to Thailand

Cats follow exactly the same three stages as dogs: permit, endorsed health certificate and arrival inspection. The vaccine list is shorter, rabies and feline panleukopenia, and the 21-day rule applies after a primary vaccine. Cats are not covered by the CDC dog rules on the way back to the US, so the return trip is simple: the cat must look healthy on arrival, and airlines or your US state may ask for a health certificate and rabies vaccination.

No breed ban, but airline limits

The embassy states that no dog breeds are banned from import into Thailand. Airlines are another matter. Long-haul carriers commonly restrict or refuse snub-nosed breeds such as pugs, bulldogs and boxers in the hold, and most impose heat rules for animals carried as cargo. Thailand's climate makes the season and the time of arrival worth planning around for any thick-coated or short-nosed dog. Our guide to the snub-nosed breed flying restrictions covers the airline side.

Most US to Thailand itineraries connect in Asia, Europe or the Middle East. Ask the airline whether the pet is accepted on every leg, whether it travels in the cabin or the hold on each, and how it is handled during the connection.

Doing it yourself versus hiring an agent

A small pet flying in the cabin with you, on one airline, into Suvarnabhumi, is a move many owners manage alone: the permit application is an email, and the station for hand-carried pets is open around the clock. An agent becomes worth the fee when the pet must fly as cargo, connect between airlines, or arrive without you on the same flight. They book cargo space, handle customs and the cargo terminal clearance during office hours, and can collect the pet on your behalf. Ask any agent how the pet will be handled at the connecting airport and who will present the documents at the Thai cargo terminal. Our guide to DIY pet relocation versus hiring a company sets out the trade-offs.

Why Thailand moves get delayed

• Applying too early or too late. Applications more than 60 days or less than 7 days before departure fall outside the window.
• Skipping the 21-day wait. A pet vaccinated for the first time last week cannot be included in a permit application yet.
• Electronic certificate only. Arriving with a printout of an electronically endorsed certificate rather than the stamped original.
• Endorsement too early. The 10-day validity starts at USDA endorsement, so a flight delay can push the certificate out of date.
• Incomplete vaccine records. Missing microchip numbers, dates of birth or vet license numbers on the certificates.
• Weekend cargo arrival. A pet shipped as cargo that lands outside the cargo station's weekday hours waits for the next working day.

Plan the trip home before you leave

Thailand appears on the CDC list of high-risk countries for dog rabies. Coming back to the US, a dog vaccinated in Thailand needs a titer from a CDC-approved lab, a government-endorsed vaccination form and an arrival at one of the US airports with a CDC-registered care facility.

A dog leaving the US now can avoid most of that. The Certification of U.S.-Issued Rabies Vaccination is completed by a USDA-accredited vet and endorsed by USDA before the dog departs. CDC lets you reuse it for returns as long as the rabies vaccine recorded on it is still valid, and dogs on that track can land at any US port that matches the CDC Dog Import Form. If your vet considers a three-year rabies vaccine appropriate, giving it before departure can keep the form usable for longer. A booster given in Thailand later counts as a foreign vaccination. Our guide to moving back to the US with a pet covers the return in detail. Cats are not covered by the CDC rules.

The first weeks in Thailand

Thailand's heat and humidity are the biggest adjustment for most pets from the US. Keep walks to the early morning and evening, make sure water is always available, and watch thick-coated and short-nosed dogs closely for signs of heat stress. Ticks and mosquitoes are a year-round concern, so ask a local veterinarian in your first weeks about parasite prevention suited to the area you live in. Keep the import license, the endorsed health certificate and the vaccination records together: the license remains valid until the pet leaves Thailand, and you will need a clean paper trail whenever the pet travels again.

A timeline that works

1. Two to three months out: check the microchip, bring all vaccines up to date, and complete the US vaccination form for the dog's eventual return.
2. At least 21 days after any primary vaccine: you can apply for the import permit.
3. About 30 days out: email the permit application to the quarantine station at your arrival airport.
4. Two to three weeks out: confirm flights land at a quarantine station airport, on a weekday if the pet flies cargo.
5. Within 10 days of arrival: accredited vet exam, health certificate and USDA endorsement, with a stamped original in hand.
6. Arrival: inspection and import license at the quarantine station.
