Most dogs don't need an import permit at all — they need a correctly timed health certificate, and the difference matters.

Start here: check whether your destination actually requires an import permit, or just a health certificate, before you assume the harder path applies to you. That single distinction — permit versus certificate — is where most owners lose weeks they didn’t need to lose.

The Permit Myth: What You Actually Need Isn’t Usually a “Permit”

Here’s the limitation that surprises almost everyone I counsel before a move: for the overwhelming majority of pet dogs, there is no formal “import permit” to apply for. An import permit, in the federal sense, is a specific Animal Care authorization tied to dogs entering the U.S. for commercial resale, adoption programs, or research — not the family dog flying to a new posting. The Bring a Pet From Another Country into the United States (Import): Animal and Plant Health Inspection Service is the federal agency that governs this space, and it draws a clear line between commercial import permits and the ordinary entry paperwork most traveling pets actually need.

What most dogs need instead is a health certificate — an official document, usually issued and endorsed within a narrow window before travel, that confirms the dog is healthy and appropriately vaccinated for the destination. Owners often ask me for “the permit,” and I have to walk back the term before we can build the actual checklist. Getting that vocabulary right early saves real time later, because the two paths have completely different timelines and completely different offices behind them.

Export, Import, and the Health Certificate: Three Different Documents

It helps to separate three things that get flattened into one word in casual conversation.

Exporting a pet from the U.S. to another country is governed by APHIS, which endorses the international health certificate your accredited veterinarian prepares — a process detailed on the agency’s page for Take a Pet From the United States to Another Country (Export): taking a pet from the United States to another country. Importing a pet dog into the U.S. is a split responsibility: APHIS handles certain categories (commercial, research, resale), while the Frequently Asked Questions on Dog Importations: Centers for Disease Control and Prevention governs the general entry requirements for dogs arriving for any reason, including simply coming home from an overseas posting. And a health certificate — the document your vet actually fills out — is neither a permit nor a passport; it’s a time-limited veterinary statement that both systems rely on.

Confusing these three is the single most common reason owners scramble in the final week before a flight.

The Sequence I Walk Clients Through

I don’t send anyone off with a stack of links and a “good luck.” I walk through the same order every time, because the order is what prevents a missed step.

First, identify the destination’s actual rules — country-specific requirements published through the APHIS pet travel resources, since entry rules are set by the destination country, not by the U.S. Second, confirm your dog’s rabies vaccination status and, if you’re coming into the U.S. from a country the CDC classifies as high risk for dog rabies, get the microchip placed before the rabies vaccine — sequencing that a growing number of destinations now enforce strictly. Third, book the veterinary exam early enough that your accredited vet has time to complete and, where required, submit the health certificate for endorsement. Fourth, reconfirm your airline’s own paperwork and crate rules separately, since airlines add requirements on top of, not instead of, the federal ones.

Skipping the order — say, vaccinating before microchipping, or booking the flight before checking the destination’s specific rules — is exactly what turns a routine relocation into a gate-side crisis.

I had a client relocating to Portugal with Baxter, a four-year-old, 68-pound golden retriever mix, on an eight-week timeline. She’d assumed she needed to “apply for a permit” and spent her first two weeks hunting for an application that didn’t exist for her situation. Once we sorted out that Portugal, as an EU destination, actually required a specific health certificate and a rabies titer timing window rather than a permit, we had time to get the paperwork right. The part she remembered most afterward wasn’t the form itself — it was how close she’d come to booking the vet exam too late in the cycle to meet the certificate’s validity window. That’s the piece owners consistently underestimate: the certificate expires, and the countdown starts the day it’s signed, not the day you planned to fly.

High-Risk Rabies Countries: Where the Paperwork Actually Gets Strict

If your dog has spent time in a country the CDC classifies as high-risk for dog rabies within the prior six months, expect additional documentation on the way back into the U.S. Specifically, U.S.-vaccinated dogs returning from a high-risk country need a Certification of U.S.-Issued Rabies Vaccination, completed by a USDA-accredited veterinarian before departure — a requirement laid out on the CDC’s page covering entry requirements for U.S.-vaccinated dogs from high-risk countries. Dogs coming from low-risk countries generally clear entry with fewer additional documents, but they still need to appear healthy, carry a microchip, and meet the minimum age requirement.

I saw this play out with a rescue import — a scruffy, roughly two-year-old terrier mix a client adopted while working abroad in a high-risk country for six months. The adoption paperwork was in order, the dog looked healthy, and the owner assumed that was the whole story. What she hadn’t done was confirm the microchip-before-vaccine sequencing or get the rabies documentation finalized through an accredited vet before leaving the country. That gap meant an anxious few days at a connecting airport sorting out documentation instead of settling the dog into a new apartment. Nothing about that dog’s health was ever in question — the entire delay was paperwork sequencing, which is exactly the kind of problem that’s fully preventable with a six-month runway.

Timing: Why Six Months of Runway Actually Matters

A short truth first: paperwork timelines rarely compress well under pressure.

Rabies titer tests, where required, can take weeks to process and often need to sit for a mandatory waiting period afterward. Health certificates typically have short validity windows, sometimes as brief as ten days for international endorsement. Microchip-before-vaccine sequencing can’t be fixed retroactively — if the order was wrong, you may be starting the vaccination clock over. Building in six months, even when the destination’s stated minimum is shorter, gives you room to absorb a delayed vet appointment, a slow lab turnaround, or a country updating its rules mid-process, which happens more often than owners expect.

My Recommendation, and the Trade-off I Won’t Pretend Away

My recommendation is unglamorous: start with the destination’s specific rules, not with a generic checklist, and build your calendar backward from the health certificate’s validity window rather than forward from your flight date. The strongest counterargument I hear is that most trips go fine without this level of front-loading — and that’s true, most of the time, for straightforward destinations with low rabies risk and simple certificate requirements. But “most of the time” is doing a lot of work in that sentence, and the failure mode when it doesn’t go fine — a dog held at a border facility, a missed flight, a certificate that expired three days before departure — is disproportionately worse than the cost of starting early.

I’ve watched enough of these unfold in real time to land firmly on the side of over-preparing. If your trip involves any international border, treat the paperwork as its own project with its own deadline, separate from booking flights or packing bags. For the broader groundwork — crate training, carrier selection, general trip prep — our Getting Started With Dog Travel guide is a reasonable place to build the rest of the plan around this paperwork timeline.

If you take one thing from this: call your accredited veterinarian and check your destination’s actual current requirements before you do anything else. Everything downstream depends on getting that first step right.
