Bringing your US dog back home after a trip abroad

In short

• Every dog coming back to the US needs a CDC Dog Import Form receipt, even a dog born and raised in the US.
• If your dog was only in low-risk countries during the last 6 months, the form is all you need.
• If your dog was in a high-risk country, it needs a Certification of US-Issued Rabies Vaccination, endorsed by the USDA before the dog leaves the US.
• Left without it? Your dog then follows the much longer foreign-vaccinated rules: titer test, government vet certificate and an animal care facility reservation.

“My dog is American, so nothing applies”: why that is wrong

Many US residents assume their dog simply comes home like they do. Since 1 August 2024, that is no longer true. The CDC rule applies to every dog entering the United States, whatever its passport, whatever its home address. Expats moving back, snowbirds returning from Mexico, military families on a new assignment and holidaymakers back from Europe all fill in the same CDC Dog Import Form.

What changes from one dog to another is not nationality, but where the dog has been in the last 6 months. That single question decides which documents you need.

Coming home from low-risk countries only

If your dog has only been in low-risk countries (most of Europe, Canada, Mexico, Japan, Australia and many more), you need the CDC Dog Import Form receipt, and that is all for the CDC. No vet document, no photo, no microchip number on the form. Your dog must still be at least 6 months old, carry a microchip and look healthy.

You can fill in the form on the day you travel. The receipt stays valid for 6 months and covers several entries, as long as your dog always comes from the same country. A snowbird driving back and forth from Canada can use one receipt for a whole season. The details are in how long the receipt is valid.

Coming home from a high-risk country: plan it before you leave

If your trip includes even one high-risk country (Brazil, Colombia, the Dominican Republic, Morocco, India, the Philippines and about a hundred others, see the full list), the return is easy only if you prepared it in the US.

The document you need

The Certification of US-Issued Rabies Vaccination is a specific CDC form, not the rabies certificate you use for your local dog license. A USDA-accredited veterinarian fills it in through the USDA online system, then the USDA endorses it. You get the endorsed copy from your vet.

When to get it

• Your dog must be microchipped before the rabies vaccination, and vaccinated when at least 84 days old (12 weeks).
• After a first rabies vaccination, the vet can complete the certification only 28 days later. A booster given with no gap in coverage counts straight away.
• The certification must be completed before the dog leaves the US. The CDC suggests talking to your vet about 30 days before travel, and USDA endorsement can take time.

How long it lasts

The certification can be reused for several trips as long as the rabies vaccine it lists is still valid (usually 1 or 3 years). Check that the vaccine will not expire while you are abroad. Carry at least 3 copies: your destination country and your return airline may keep one.

On the way back, you fill in a high-risk CDC Dog Import Form (photo, microchip number, travel details, the certification). That receipt covers one entry, on the date and at the port you declare. Your dog can enter at any airport, land border or seaport, as long as it matches the receipt. The full pathway is in US-vaccinated dogs from high-risk countries.

What if you already left without the certification?

This is the most common trap for returning families, and there is no way to fix it from abroad: the CDC requires the certification to be completed before departure.

Option 1: an older USDA export certificate

If your dog left with a USDA-endorsed export health certificate issued on or before 31 July 2025, the CDC still accepts it instead of the certification. It must be viewable in the USDA database and show your dog’s age, microchip number and a valid US rabies vaccination given after the microchip. Any export certificate issued after that date is not accepted for the return.

Option 2: the foreign-vaccinated pathway

Without either document, your American dog is treated like a foreign-vaccinated dog from a high-risk country. That means:

• a Certification of Foreign Rabies Vaccination and Microchip, endorsed by an official government vet of the country you are in, completed no more than 30 days before travel;
• a titer test (a blood test that measures rabies antibodies) from a CDC-approved laboratory, drawn at least 30 days after vaccination and at least 28 days before entry;
• a reservation at a CDC-registered animal care facility, and a direct flight into that facility’s airport, with an exam and a US rabies booster on arrival (you pay).

Start early: the titer timing alone takes weeks. Everything is explained in foreign-vaccinated dogs from high-risk countries.

Option 3: let the high-risk stay fall out of the window

The CDC looks back 6 months. If your dog moves to a low-risk country and stays there until its last high-risk visit is more than 6 months old, it comes home as a low-risk dog, with the form only. This works for long stays abroad, not for a quick return.

A checklist before you fly out

1. List every country your dog will visit, including layovers where it clears customs.
2. If one is high-risk: check the microchip, the vaccine dates and the expiry date of the rabies vaccine.
3. Ask a USDA-accredited vet for the Certification of US-Issued Rabies Vaccination, early enough for USDA endorsement.
4. Print at least 3 copies and keep a photo on your phone.
5. Before the return flight, fill in the CDC Dog Import Form for the exact date and arrival port.

The outbound trip has its own rules, set by the country you visit. If you are flying to Europe, see traveling between the US and Europe. For the USDA step itself, see how USDA endorsement works.
