Guam Pet Travel: Rules, Quarantine & How to Fly

Yes, you can bring your pet to Guam, but the process is strictly regulated and requires advance planning. Guam is a U.S. territory with a rabies-free status, so the government enforces a quarantine and import permit system to keep it that way. The rules differ depending on whether you are coming from the U.S. mainland, another rabies-free country, or a rabies-endemic area, and getting everything right before you fly is essential to avoid a lengthy or costly quarantine.

Why Guam Has Strict Pet Import Rules

Guam has been rabies-free for decades, and the local government works hard to maintain that status. Because the island is home to a unique ecosystem and a small veterinary infrastructure, an outbreak of rabies would be devastating. As a result, the Guam Department of Agriculture’s Veterinary Diagnostic Laboratory (VDL) oversees all animal imports. Every dog and cat entering Guam must have an import permit, proof of rabies vaccination, and a microchip for identification. The rules are designed to prevent the introduction of rabies and other animal diseases, and they are enforced at the point of entry.

Step-by-Step: Preparing Your Pet for Guam

The process is similar to bringing a pet to Hawaii or Australia, but with its own timeline. Start at least 30 days before your travel date, and ideally 60–90 days out if your pet is not already fully vaccinated.

• Microchip first: Your pet must have an ISO-compliant 15-digit microchip. If your pet has a different chip, you’ll need to bring a compatible scanner or have the chip replaced before starting the process.
• Rabies vaccination: Your pet must be vaccinated against rabies at least 30 days before arrival and no more than 1 year (for a 1-year vaccine) or 3 years (for a 3-year vaccine) before arrival. The vaccine must be given after the microchip is implanted.
• Apply for an import permit: You must submit an application to the Guam VDL, along with proof of microchip, rabies vaccination, and a health certificate issued by a USDA-accredited veterinarian within 14 days of travel.
• Receive your permit: The VDL will review your paperwork and issue an import permit, usually within a few weeks. You must carry this permit when you travel.
• Arrange flight and entry: Book your flight with an airline that accepts pets, and notify them in advance. You’ll also need to arrange for a USDA-endorsed health certificate if you’re flying from the U.S. mainland.

Quarantine Rules: What to Expect

Guam does have a quarantine facility, but most pets that meet all requirements can avoid quarantine or have a very short stay. The official policy is that pets arriving with proper documentation may be released after a brief inspection, usually within a few hours. However, if your pet arrives without a valid import permit, missing rabies vaccination, or from a rabies-endemic country, it may be quarantined for up to 120 days at your expense. The quarantine facility is located in Mangilao, and you are responsible for all boarding fees. In rare cases, pets may be denied entry and sent back, so it is crucial to follow every rule.

Flying to Guam: Airlines and Routes

Guam’s main airport is Antonio B. Won Pat International Airport (GUM). Most flights from the U.S. mainland connect through Honolulu, Hawaii, or Tokyo, Japan. United Airlines is the primary carrier serving Guam, and they have specific pet policies. Pets may travel as checked baggage or in the cabin, depending on size and the aircraft. For example, small dogs and cats may be allowed in the cabin on some flights, but larger pets must go in the cargo hold. You must contact the airline directly to confirm availability, as there are limits on the number of pets per flight. From Asia, other carriers like Japan Airlines or Korean Air may also have pet options, but you’ll need to check each airline’s rules.

Costs to Budget For

Bringing a pet to Guam is not cheap. Here are the typical costs you should plan for:

• Import permit fee: The Guam VDL charges a fee for processing the import permit, which is around $50–$100 per pet.
• Veterinary visits and health certificate: Expect to pay $50–$200 for the exam and paperwork, plus a USDA endorsement fee (around $40–$100).
• Airline fees: Checked baggage pets typically cost $150–$300 each way; in-cabin pets may be $100–$200.
• Quarantine costs (if needed): If your pet is quarantined, you’ll pay a daily boarding fee of around $10–$20 per day.
• Microchip and vaccinations: If your pet isn’t already chipped and vaccinated, add another $50–$150.

Common Pitfalls and How to Avoid Them

Many pet owners run into issues because they underestimate the timeline or misunderstand the rules. One common mistake is assuming that a health certificate from a local vet is enough—Guam requires USDA endorsement if you’re flying from the U.S. Another is thinking that a 3-year rabies vaccine is valid if it was given less than a year ago, but the 30-day minimum still applies. Also, be aware that some airlines do not allow pets in the cabin on flights to Guam due to the long duration and aircraft type. Always double-check with the airline and the Guam VDL before booking your flight.

Alternatives: Shipping vs. Flying with Your Pet

If you’re moving to Guam and cannot fly with your pet in the cabin or as checked baggage, you can use a professional pet transport service. These companies handle all the paperwork, book the flight, and ensure your pet is comfortable. However, they are expensive, often costing $1,000–$3,000 or more. Another alternative is to fly your pet as cargo, which is sometimes the only option for large dogs. Cargo shipping is generally safe if you use a reputable airline and follow all regulations, but it requires more planning and involves more stress for the pet. For most people, flying with the pet on the same flight is the best balance of cost and convenience.

Frequently Asked Questions

Can I bring my pet to Guam without a permit?
No. A valid import permit from the Guam Department of Agriculture is required for all dogs and cats. If you arrive without one, your pet will be quarantined or denied entry.

How long does the import permit take to process?
Typically 2–4 weeks, but it can take longer if your paperwork is incomplete. Apply at least 30 days in advance, and ensure all documents are in order.

Is there a quarantine for pets from the U.S. mainland?
If your pet meets all requirements (microchip, rabies vaccine, health certificate, and permit), there is no quarantine—just a brief inspection at the airport. If any requirement is missing, quarantine can be up to 120 days.

What if my pet is not a dog or cat?
Other animals, such as rabbits, birds, or reptiles, have different import rules. You must contact the Guam VDL directly for guidance, as some species may be prohibited.

Can I take my pet on a carry-on to Guam?
Some airlines allow small pets in the cabin, but not all flights to Guam have that option. Check with your airline early, as there are limited spots.
