To fly with a service dog internationally, you must meet both your U.S. airline’s service animal rules and the destination country’s animal-import laws. U.S. airlines require the DOT Service Animal Air Transportation Form for a trained service dog, but foreign countries set their own entry requirements: rabies vaccination, microchipping, blood titer tests, health certificates, and sometimes quarantine. Service dogs are not exempt from these import laws, so international travel with a service dog takes months of planning across airlines, the USDA, and the destination’s veterinary authority.
Two rule sets: airline plus destination country
International travel with a service dog means clearing two separate hurdles. First, your U.S. airline requires the DOT service animal form and expects a trained service dog to behave in the cabin. Second, the destination country’s import authority sets veterinary requirements the airline does not control. A dog can meet every airline rule and still be turned away at the border if the country’s paperwork is incomplete, so plan for both.
Your U.S. airline's requirements
On the outbound U.S. flight, airlines apply the 2021 DOT rule: a trained service dog flies in the cabin free with a completed DOT Service Animal Air Transportation Form, plus a relief attestation for flights of eight or more hours. The service dog must fit at your feet and behave. These airline rules cover the flight itself, not entry into the foreign country.
Destination country import laws
Every country sets its own rules for importing animals, and service dogs are not exempt. Common requirements include a valid rabies vaccination, an ISO-standard microchip, a rabies antibody blood titer test from an approved lab, an official health certificate, and treatment for parasites. Rabies-free and island nations often add quarantine or long waiting periods, so research the destination’s rules for service dogs early.
USDA endorsement and health certificates
Most countries require an export health certificate completed by a USDA-accredited veterinarian and endorsed by the USDA Animal and Plant Health Inspection Service (APHIS). The exam and endorsement must usually happen within a narrow window before departure, often 10 days. Build the vet visit and USDA endorsement into your timeline, because a service dog cannot enter most countries without this certificate.
Rabies blood tests and timing
Many countries require a rabies antibody titer test drawn a set number of days after vaccination and a waiting period, sometimes three months, before the dog may enter. This is the single longest lead-time item for international travel, so start the rabies steps for your service dog well ahead of the trip. Missing the waiting period can force a quarantine or bar entry entirely.
Countries with quarantine
Some destinations, including several island and rabies-free nations, impose quarantine even on a fully documented service dog if the import steps are not completed in the correct order and timing. Others waive quarantine when every requirement is met in advance. Because rules differ so much between countries, confirm the current policy with the destination’s veterinary authority rather than relying on general guidance.
Airline paperwork for the return flight
Re-entering the United States has its own rules. The CDC sets dog-import requirements for returning to the U.S., which have included rabies documentation and advance forms depending on where the dog has been. Confirm the current CDC dog-import rules before you fly home so your service dog is not delayed at the U.S. border on the return leg.
Cabin travel on foreign carriers
If a leg of your trip is on a non-U.S. airline, the DOT rule may not apply, and that carrier sets its own service dog policy. Some foreign airlines accept trained service dogs in the cabin; others require them to travel as cargo or apply different documentation. Check each airline on your itinerary, not just the U.S. carrier, when you travel internationally with a service dog.
Building your timeline
Work backward from your travel date: rabies vaccination and microchip first, then the blood titer test and its waiting period, then the USDA-endorsed health certificate in the final days, then the airline forms. Because the blood test waiting period can run months, most handlers start international planning for a service dog at least four to six months out.
Preparing the dog itself
Beyond paperwork, prepare the service dog for long-haul travel: practice settling for many hours, acclimate it to airports and crowds, and plan relief stops in unfamiliar terminals. Bring water, a mat, and copies of every document. A calm, well-trained service dog handles international travel far better than one that has never done a long flight.
Registering your service dog for international travel
Registration is not required, but many handlers document their service dog with USAR to carry a verifiable record alongside the country-specific paperwork. A USAR registration provides a digital and printed ID and a scannable QR page. It does not replace the DOT form, the USDA health certificate, or the destination country’s import documents, all of which international travel with a service dog requires.
Emotional support animals and pets abroad
Emotional support animals are not recognized as service animals for international air travel, so an emotional support animal flies as a pet under each airline’s pet rules. Even a trained service dog is treated as an ordinary animal by a foreign country’s border, which regulates all animals, dogs and cats alike, the same way. Plan for your service dog to face the same import rules any pet would when you travel to another country.
Vaccinations and forms every country requires
Most countries require current vaccinations, an ISO microchip, and official forms before any animal, including a service dog, may enter. Rabies vaccinations are universal, and many countries add a rabies blood test and parasite treatment. The forms must be completed and, in most cases, endorsed by the USDA before the trip. Because these vaccinations and forms have strict timing, build them into your planning months before you fly with the service dog.
Training, behavior, and long-haul flights
International trips usually mean long-haul flights, which test a service dog’s training. A dog with solid training settles for hours, ignores unfamiliar crowds, and relieves itself on schedule. Before the trip, practice long settles and airport visits so the training holds up. The airlines on your itinerary each set their own service dog rules, so confirm every carrier and complete each airline’s forms before you travel to another country.
Working with airlines and destination countries
Successful international travel with a service dog means coordinating airlines and countries at once. Contact each airline about its service animal policy and each destination and transit country about its import rules. Some countries quarantine animals that arrive without complete paperwork; others waive it when every requirement is met. Because the rules differ by country, confirm the current policy with the destination’s veterinary authority as part of your trip planning.
Only dogs, pets, and animals at the border
For international travel, only dogs are recognized as service animals by U.S. airlines, while emotional support animals and emotional support dogs are treated as pets. Every destination regulates animals at the border, so pet dogs and a service animal alike need animal health certificates, an import permit, and sometimes an approved port of entry. Comfort animals and other species may be denied entry, and dogs entering many countries face additional requirements set to prevent disease control problems such as the new world screwworm.
Forms, vaccinations, and the USDA
Complete all the forms before you travel: the DOT service animal forms for the airline, the USDA-endorsed health certificate for the foreign country, and proof of vaccinations. Find details on the USDA website for each international destination, because rules apply differently by country and additional requirements are common. Cats and dogs both need current vaccinations and, in many countries, a rabies blood test. Build the training, forms, and vaccinations into your planning so the service dog meets every requirement before the trip.
Airlines, connections, and returning home
Many airlines and flights operated by partner carriers each set their own rules for a service animal, so confirm every airline on the itinerary, including carriers such as British Airways. A dog must behave properly and be permitted in the cabin, out of the exit row, on each leg of the trip. To re-enter the United States, follow the CDC and disease control rules for dogs re-entering the country. Contact each airline and country to determine the requirements, and note them for future trips.

Common questions about flying with a service dog internationally
Can I fly internationally with a service dog?
Yes, but you must meet both your U.S. airline’s DOT service animal rules and the destination country’s animal-import laws, which include rabies vaccination, microchipping, blood tests, and health certificates.
Are service dogs exempt from country import rules?
No. Service dogs must meet the same veterinary import requirements as any dog. The service-animal exemption applies only to airline pet fees, not to a country’s border health laws.
What paperwork does international travel with a service dog require?
The DOT Service Animal form for the U.S. flight, a USDA-endorsed export health certificate, rabies vaccination and often a rabies blood titer test, an ISO microchip, and the destination country’s import documents.
How far ahead should I plan international travel with a service dog?
At least four to six months. The rabies blood test and its mandatory waiting period, sometimes three months, are the longest lead-time items.
Do foreign airlines follow the DOT service dog rule?
Not necessarily. The 2021 DOT rule binds U.S. carriers. Non-U.S. airlines set their own service dog policies, so check every carrier on your itinerary.
What do I need to bring my service dog back to the U.S.?
Follow the CDC’s current dog-import requirements for returning to the United States, which can include rabies documentation and advance forms depending on where the dog has traveled.
