Traveling internationally with a dog is mostly a paperwork problem, and paperwork problems are solved by starting early.

The limitation nobody mentions until it’s too late

Here’s the surprising part: your dog’s health has almost nothing to do with whether he’s allowed into another country. What matters is a piece of paper filed on the right day, by the right kind of veterinarian, with the right stamp on it. I’ve had clients assume that a healthy, up-to-date dog is a travel-ready dog. It isn’t. A dog can be in perfect condition and still get denied boarding because a rabies titer was drawn four days too late, or because the health certificate was signed the week before departure instead of within the window the destination country requires.

Before you book anything, work through this checklist:

• Confirm your destination country’s specific pet-entry rules directly — timelines vary from a few days’ notice to a mandatory months-long waiting period.
• Verify your dog’s rabies vaccine is current and was given after the microchip was implanted, not before.
• Ask your vet, early, whether your destination requires a FAVN rabies titer test — some do, some don’t, and the difference changes your timeline by months.
• Book an appointment with a USDA-accredited veterinarian for the export health certificate, timed to your destination’s required issue window.
• Check your airline’s pet policy separately from the country’s entry rules — they are not the same requirement, and airlines add their own limits on breed, crate size, and cabin space.
• Build in a buffer week before departure for APHIS endorsement, which can be done by mail or in person but still takes processing time.

Everything below walks through that list in the order it actually happens, from the first vet visit to the moment you land.

Four to six months out: figure out what your destination actually requires

This is the step people skip, and it’s the one that causes the most heartbreak. Every country sets its own rules, and they range from “show a rabies certificate at customs” to “your dog needs a blood test drawn at least 30 days after vaccination and then a mandatory three-month wait before travel.” The APHIS pet travel resources cover country-specific entry requirements for more than 130 destinations, and that’s the first thing I tell clients to check — not their vet, not a forum, not a travel agent, but the actual government requirement page for the country they’re flying into.

If you’re headed to the European Union, the requirements are unusually well-documented. According to the European Commission, a dog entering the EU from a non-EU country generally needs an ISO-compliant microchip, a current rabies vaccination given after that microchip, and — depending on the country of origin’s rabies status — a rabies antibody titration test performed by an approved laboratory at least 30 days after vaccination. That titer, often called a FAVN test, has to clear a threshold before your dog is considered protected enough to enter. If the country you’re leaving from is considered higher-risk for rabies, this test isn’t optional, and it can’t be rushed. Once your dog has a satisfactory titer result and keeps up with rabies boosters on schedule, many destinations won’t require the test again for that dog’s lifetime.

I once worked with a family bringing their eight-year-old Cavalier King Charles Spaniel to France for a two-year work relocation. They’d booked flights for six weeks out before anyone mentioned the titer requirement to them. The blood draw itself was simple — one visit, one vial — but the required 30-day wait after vaccination, plus lab turnaround, plus the mandatory waiting period some routes still apply, meant they were staring down a trip they physically could not make on schedule. They ended up delaying the move by three months. Nobody’s health was at risk. It was purely a calendar problem, and it’s the single most common one I see with international travel.

Two to three months out: microchip, vaccine timing, and the export health certificate

If your dog isn’t already microchipped, that comes first, and the order matters — most destinations only recognize a rabies vaccine given after the microchip is in place. A vaccine administered before the chip generally doesn’t count for entry purposes, which means starting from scratch on the vaccine timeline. This is exactly the kind of preventive-care sequencing question I’d walk a client through at a wellness visit anyway, but for international travel it becomes a hard requirement rather than a suggestion.

Around six to ten days before departure — though this window varies by destination, so confirm the exact number for your country — you’ll need an export health certificate from a USDA-accredited veterinarian. Not every vet holds this accreditation, so confirm it ahead of time rather than assuming your regular clinic can issue it. The certificate typically needs to be endorsed by your local APHIS office after your vet completes it, and that endorsement step is where timelines quietly slip. Build a few extra business days into your plan for it.

Dogs returning to the United States face their own layer of rules. Per the CDC, a U.S.-vaccinated dog that has spent time in a country considered high-risk for dog rabies within the prior six months needs a Certification of U.S.-Issued Rabies Vaccination form, completed by a USDA-accredited vet and submitted before the dog leaves the U.S. — it cannot be issued retroactively once your dog is already abroad. Dogs coming from low-risk countries generally just need a completed CDC Dog Import Form and don’t have to show proof of rabies vaccination at all. Either way, dogs must be at least six months old and appear healthy at entry.

Three to four weeks out: book the airline, not just the country

Meeting a country’s entry requirements gets your dog legally allowed to arrive. It does not get your dog on the plane — that’s a separate set of rules set by the airline, and this is where the myth-versus-reality gap really opens up. Owners often assume that if a dog is small enough for an in-cabin carrier, any airline will take them internationally. In practice, airlines cap the number of pets per cabin, restrict certain breeds (especially brachycephalic breeds like French Bulldogs and Pugs) from cargo travel entirely, and some routes don’t accept pet cargo above certain outdoor temperatures at either end of the flight. Call the airline directly and get your dog’s reservation confirmed in writing — don’t assume a seat booking automatically includes a pet slot.

This is also the point to reconsider crate training if your dog hasn’t spent real time in one. A long-haul flight is not the moment to introduce a crate for the first time. I ask clients to have their dog eating meals and resting comfortably in the travel crate for at least two to three weeks before a flight, with the door open at first and then closed for short stretches. A dog who’s anxious about confinement doesn’t need a sedative for a plane — she needs practice, and dogs generalize confinement comfort with structure and repetition, not any single training session.

Health-wise, this is a reasonable window to schedule a general wellness exam. Long flights, time-zone changes, and unfamiliar climates are real stressors, and a preventive-care checkup gives you a chance to flag anything — joint stiffness, weight changes, coat condition — that might need attention before you’re navigating it in an unfamiliar country. Structure and function, not diagnosis: this visit is about baseline, not crisis.

One to two weeks out: the final document check

By this point your dog should have the microchip, current rabies vaccination given after the chip, any required titer result in hand, and a signed, dated export certificate within its valid window. Photocopy everything — digital photos on your phone are a reasonable backup, but a paper copy in a folder is what customs officials expect to see. I’ve watched a trip nearly derailed at a departure gate because the only copy of a health certificate was a screenshot with a cropped signature line. Airline and customs staff want the physical original, or at minimum a complete, legible copy.

Reconfirm the airline reservation forty-eight hours out, and check that your carrier still meets the airline’s exact size and ventilation specifications — airlines occasionally update crate requirements between when you book and when you fly. If your dog needs food or water during a long layover, know your destination’s rules on bringing dog food across the border; some countries restrict animal-origin ingredients in imported pet food, separate from the pet-entry paperwork entirely.

Arrival: what actually happens at customs

Most arrivals are anticlimactic in the best way — an agent reviews your documents, occasionally checks the microchip against the paperwork, and waves you through. Where it goes sideways is almost always a documentation gap: a titer drawn on the wrong day, a certificate signed outside the valid window, or a vaccine given before the microchip. None of those are health problems. They’re calendar problems, and they’re the reason I tell every client planning international travel to start the country-specific research the same week they start looking at flights, not after they’ve already booked them.

If you’re just beginning to plan a trip and want the broader groundwork — vaccines, general readiness, what to pack — our guide on getting started with dog travel is a useful starting point before you dive into destination-specific rules.

The bottom line

International dog travel is entirely manageable, but it rewards planning far more than it rewards flexibility — start with your destination’s specific entry rules the same day you start looking at flights, and build your vet visits, titer test, and health certificate around that country’s timeline rather than your own.
