What do I need to know about flying internationally with a dog?

Short answer
International travel typically requires a health certificate, up-to-date vaccinations, an active microchip, and sometimes a rabies titer test or import permit specific to the destination country, all with lead times that can stretch to several months. Quarantine rules also vary significantly, with some destinations requiring none for prepared pets and others requiring a mandatory holding period, so researching the exact destination early is essential.
The paperwork trail that takes the most time
A rabies antibody titer test, required by some countries before entry, needs blood drawn a set number of months ahead and a waiting period after the result before travel is permitted, which means this single step can take longer to arrange than almost any other part of trip planning. Starting this process as early as six months before a planned trip gives comfortable room for delays or repeat testing if needed.
Understanding quarantine differences
Some countries and regions require no quarantine at all for pets arriving with the correct paperwork completed in advance, while others still require a mandatory holding period on arrival, which can range from a few days to several weeks depending on the destination and how well documented the pet's health history is. Checking the destination's specific current policy, rather than assuming rules from one country apply elsewhere, avoids a serious surprise on arrival.
Choosing airlines and routes carefully
Not every airline flies pets internationally, and those that do often have separate booking processes, additional fees, and specific carrier or cargo requirements that differ from domestic pet travel. A direct flight reduces the number of handling transitions and total travel time, both of which matter more for international trips that are often considerably longer than domestic ones.
Working with professionals who handle this regularly
A vet experienced in international pet travel paperwork, or a specialized pet relocation service for a particularly complex destination, can help avoid costly mistakes like a titer test drawn slightly outside the required window, which some countries reject outright and require repeating from scratch.
Key takeaways
- A rabies titer test, where required, can take months to arrange and should be started early.
- Quarantine rules vary widely by destination, from none required to a mandatory holding period.
- Not all airlines fly pets internationally, and processes differ from domestic pet travel.
- A vet experienced in international pet travel paperwork helps avoid costly documentation mistakes.
