If you’re planning to travel with your dog — whether it’s a quick flight to another state or a move overseas — chances are you’ll need a health certificate before you go. These documents confirm your dog is healthy enough to travel, but the rules around them can get confusing fast, especially since domestic and international requirements aren’t the same.

This guide walks through what a dog health certificate actually is, how long it stays valid, and the steps to get one for your specific trip.

What Is a Dog Health Certificate for Travel?

A dog health certificate for travel is officially known as a Certificate of Veterinary Inspection (CVI). It’s an official document issued by a licensed veterinarian confirming that your dog has been examined, appears healthy, and is up to date on required vaccinations.

Think of it as proof that your dog is fit to travel. Airlines, states, and countries all use it to reduce the risk of spreading disease through animal movement — it’s not just paperwork for the sake of paperwork.

Do You Need One for Domestic or International Travel?

In most cases, yes — whether you’re flying across state lines or leaving the country, some version of a health certificate will be required. The difference is in the details. Domestic travel usually has more flexible timelines and fewer extra steps, while international travel typically adds a federal endorsement process on top of the basic exam.

Domestic Travel Requirements

State-to-State (Interstate) Requirements

Here’s something that surprises a lot of pet owners: the USDA doesn’t actually regulate how pets move between states. Interstate requirements are set individually by each receiving state or territory. That means the rules for taking your dog to Florida might look nothing like the rules for taking it to Colorado.

Before you travel, check directly with your destination state’s animal health office. Requirements can include proof of vaccination, specific testing, or a certificate issued within a set number of days — and they change often enough that it’s worth confirming close to your travel date.

Airline Requirements for Domestic Flights

Even if your destination state doesn’t require anything unusual, your airline might. Most airlines cap the validity of a health certificate at 10 days for domestic flights, regardless of what the state technically allows. It’s common for a state to permit a 30-day window while the airline still insists on something issued within 10 days of departure — so in practice, the airline’s rule is often the one that actually limits your timeline.

Confirm the exact requirement with your airline before booking your vet appointment, since this varies by carrier.

International Travel Requirements

International travel adds a layer that domestic trips don’t have: USDA endorsement.

For most international destinations, the process looks like this:

1. Your dog is examined by a USDA-accredited veterinarian — not just any licensed vet.
2. The veterinarian completes the appropriate health certificate, often the United States Interstate and International Certificate for Health Examination for Small Animals (APHIS Form 7001).
3. The certificate is submitted to USDA APHIS for endorsement, meaning USDA reviews and countersigns it — typically with a stamp or embossed seal.
4. The original, endorsed paper document travels with your dog. Electronic copies generally aren’t accepted by officials at the destination country, even if the certificate was processed electronically along the way.

Requirements vary significantly by destination country, so check your specific country’s rules well before the trip rather than assuming one process fits everywhere.

New CDC Rules for Dogs Entering or Returning to the U.S. (2024)

If your dog is entering the United States — including a U.S. dog returning home after traveling abroad — there’s an additional set of requirements from the CDC, separate from USDA’s process.

As of August 2024, the CDC requires dogs entering or returning to the U.S. to:

• Be at least 6 months old at the time of entry
• Have an ISO-compatible microchip implanted before any required rabies vaccination
• Be registered through the online CDC Dog Import Form before arrival
• Appear healthy on arrival (a sick-appearing dog may be isolated or need further veterinary evaluation)

These requirements apply on top of anything USDA or your destination state requires, and they’ve caught quite a few pet owners off guard simply because they’re relatively new. Since CDC guidance can be updated, it’s worth checking the current CDC dog import page directly before your trip.

How Long Is a Dog Health Certificate Valid?

Validity windows are where most of the confusion happens, because the “correct” answer depends on who’s asking — the state, the airline, or the destination country.

Because these windows can be strict, book your vet appointment around the shortest window that applies to your trip — usually the airline’s requirement if you’re flying.

How to Get a Dog Health Certificate (Step-by-Step)

1. Confirm your requirements first. Check your airline, your destination state, and (if applicable) your destination country’s rules before booking anything.

1. Find a USDA-accredited veterinarian. Not every vet can issue this certificate — call ahead and ask specifically whether they’re USDA-accredited, especially for international travel.
2. Book the appointment within the correct window. Base this on the strictest requirement that applies to your trip, often the airline’s 10-day rule.
3. Bring your dog’s full vaccination records. Your vet needs to verify rabies vaccination status and any other required vaccines.
4. Get the certificate completed and signed. For domestic travel, this is often the final step.
5. For international travel, send it for USDA endorsement. Your vet’s office can usually guide you through this submission process.
6. Keep the original document with you during travel. Copies or digital versions typically aren’t accepted at international borders.

Frequently Asked Questions

How long is a dog health certificate valid for travel?
It depends on the type of travel. Domestic air travel is commonly limited to 10 days, domestic non-air travel can be valid up to 30 days depending on the state, and international timelines vary by destination country.

Can any vet issue a dog travel health certificate?
Not for every situation. Domestic-only certificates can sometimes be issued by any licensed vet, but international travel specifically requires a USDA-accredited veterinarian.

Do I need a USDA-endorsed certificate for domestic travel?
Generally, no. USDA endorsement is mainly required for international travel. Domestic travel is governed by state and airline requirements instead.

What’s different about traveling internationally with a dog vs. domestically?
International travel adds a USDA endorsement step and, in many cases, additional country-specific requirements, while domestic travel relies mainly on state rules and airline policy.

What happens if my dog’s certificate expires before my trip?
You’ll need a new exam and certificate. Since certificates can’t be backdated or extended, schedule your vet visit as close as possible to your actual travel date, within the required window.
