Pet Transport to Puerto Rico in 2026: Requirements, Cost, and How-To

Moving a pet to Puerto Rico is a domestic trip, not an international one. Because Puerto Rico is a US commonwealth, there is no import permit, no CDC dog form, and no USDA endorsement. You need an interstate health certificate from an accredited vet (issued within 10 days), current rabies, and a parasite treatment noted on the certificate. Budget roughly $150 in-cabin or $900 to $2,000-plus by professional shipper.

Why Puerto Rico counts as domestic, not international

This is the single fact that changes everything about your move, and most travel checklists get it wrong. Puerto Rico is an unincorporated territory of the United States, so a flight from the mainland to San Juan is treated like a flight to Hawaii or Alaska: it stays inside the federal system. There is no customs line, no foreign import process, and no need for the CDC Dog Import Form that the US now requires for dogs entering from abroad. According to the USDA APHIS pet travel guidance, federal endorsement of a health certificate is reserved for international exports, which a Puerto Rico trip is not.

What you do still need is a territory-level health certificate and current vaccines, because the Puerto Rico Department of Agriculture sets its own entry rules and airlines enforce them at the gate. So the paperwork is real, it is just simpler and cheaper than a true overseas move. If you have read our guide on Hawaii pet transport, the mental model is similar with one big exception: Hawaii runs a rabies quarantine program, and Puerto Rico does not. There is no quarantine on arrival in Puerto Rico for a compliant dog or cat.

Contrast that with a genuine cross-border move like our pet transport to Mexico walkthrough, where you cross into a foreign animal-health jurisdiction. Puerto Rico skips all of that. The practical upshot: you are looking at one vet visit and a carrier reservation, not a permit application.

The actual entry requirements

Here is what the Puerto Rico Department of Agriculture and the airlines expect for a dog or cat arriving with its owner. Always confirm the current version directly with the Puerto Rico Department of Agriculture entry document hosted by USDA APHIS and with your specific airline before you fly, because details shift.

Interstate health certificate: issued by a USDA-accredited veterinarian. Most sources put the window at within 10 days of travel, and several note the certificate stays valid for up to 30 days from the inspection date. Some airline desks reference a tighter pre-arrival window, so book the vet visit close to your departure and ask the airline for its exact cutoff.

Rabies vaccination: required for dogs and cats four months and older. Reporting from pet-travel services indicates the shot should be active and given at least 30 days before arrival, with proof on a vaccination certificate. Confirm timing with your vet.

External-parasite treatment: a flea and tick treatment, commonly noted as within 72 hours of arrival, with the product name and date written onto the health certificate itself. If that line is missing, Puerto Rico can reject the certificate.

Identification: official individual ID. An ISO 15-digit microchip is strongly recommended, and many sources accept a collar with a metallic ID tag as the minimum.

No import permit and no quarantine for a pet entering with its owner.

Because the parasite line and the certificate-date rules are the two items travelers most often miss, treat them as your pre-flight checklist anchors. A certificate that is technically valid but missing the written parasite product can still get you turned away.

Requirements and cost at a glance

Ranges above are drawn from published airline fees and pet-relocation pricing pages and are estimates, not quotes. A small dog flying in cabin with you can keep the whole trip under a few hundred dollars in fees. A large dog that cannot fly in cabin is a different financial conversation, which is the next section. For a broader cost framework across routes, see our breakdown of how much pet transport costs.

In-cabin vs cargo: the size question decides your route

In-cabin (small pets)

If your pet plus carrier stays under roughly 20 pounds and fits in a soft carrier that slides under the seat, cabin travel is the cheapest and least stressful path. Major carriers that serve San Juan, including JetBlue, American, United, and Delta, allow in-cabin pets on these routes. Per the JetBlue traveling-with-pets policy, the carrier must be FAA-approved and fits under the seat, and JetBlue specifically flags that Puerto Rico requires vaccination documentation. Published in-cabin fees in 2026 cluster around $125 to $150 each way, and most aircraft cap the cabin at a handful of pets, so reserve your pet's spot three to four weeks ahead.

Cargo and the heat problem (large pets)

If your dog is too big for the cabin, the picture gets harder, and the reason is San Juan's climate. According to American Airlines Cargo policies and restrictions, airlines impose temperature embargoes that block live-animal cargo when it is too hot on either end of the trip, typically around 85 degrees Fahrenheit. San Juan sits at or above that line for much of the year, so summer cargo bookings are routinely embargoed. On top of that, several major US airlines now restrict belly-cargo pet shipping to active-duty military and government relocations, which removes the standard cargo option for many civilian movers.

That leaves a few realistic routes for a large dog: a dedicated cargo carrier such as Amerijet out of Miami that runs climate-controlled animal transport, or a professional pet shipper that books the route, handles paperwork, and manages the heat window for you. Brachycephalic (flat-faced) breeds such as bulldogs, pugs, and Boston terriers are banned from cargo by most carriers, and Puerto Rico's heat makes that a genuine safety rule, not red tape. Most airlines still allow flat-faced pets in the cabin if they fit the carrier.

What it costs, in plain numbers

Your total lands in one of three bands. A small pet flying in the cabin with you costs the airline fee (about $125 to $150 each way) plus vet paperwork, so call it a few hundred dollars all-in. A do-it-yourself cargo or freight booking, where it is available, runs an estimated $300 to $1,200 in airline freight depending on weight and route, per pet-relocation cost references. A full door-to-door professional relocation to Puerto Rico is the priciest tier: one national shipper lists a base handling fee near $1,197 for Alaska, Hawaii, and Puerto Rico moves, and totals commonly run $900 to $2,000-plus once crate, ground transport, and admin are added.

Step by step: getting your pet to Puerto Rico

Confirm the rules in writing. Read the current Puerto Rico Department of Agriculture entry requirements and your airline's pet page. Rules change, and the gate agent enforces the airline's version.

Decide cabin or cargo. Weigh your pet plus an empty carrier. Under roughly 20 pounds and carrier-sized means cabin. Larger means cargo carrier or a professional shipper.

Reserve the pet spot early. Cabin slots are capped per flight. Call three to four weeks ahead, especially in summer when heat embargoes squeeze cargo capacity onto fewer viable dates.

Microchip and update vaccines. Get an ISO microchip if your pet lacks one, and make sure rabies is active with enough lead time before arrival.

Book the vet visit close to departure. Schedule the accredited-vet exam and health certificate inside the ~10-day window, and confirm the vet writes the flea and tick product name and date on the certificate.

Buy an IATA-compliant carrier. A soft under-seat carrier for cabin, or a rigid airline-approved kennel sized for cargo with ventilation on all sides.

Plan around the heat. Aim for early-morning or late-evening flights, and avoid tight connections through hot hub cities that could trigger an embargo.

Carry every document. Bring the original health certificate and rabies proof to the gate. No paperwork, no boarding.

Bringing a cat to Puerto Rico

Cats follow the same domestic logic as dogs. No import permit, no quarantine, and the same health-certificate and rabies expectations for cats four months and older. The good news for cat owners is that nearly every cat fits the cabin size limit, so the cargo and heat-embargo headaches that complicate large-dog moves rarely apply. Reserve the cabin pet spot early, keep the carrier under the seat, and carry the same paperwork. A flea and tick treatment noted on the certificate applies to cats as well.

How we sourced this

We cross-checked the regulatory framing against USDA APHIS pet-travel guidance and the Puerto Rico Department of Agriculture entry document, pulled in-cabin fees and carrier rules from airline pet pages (JetBlue and American Airlines Cargo), and bracketed shipper pricing from published pet-relocation cost references. Prices and timing windows are presented as ranges because they vary by airline, vet, season, and pet size. Confirm the current numbers with your airline and the Puerto Rico Department of Agriculture before you book.

Do I need a permit or USDA endorsement to bring my pet to Puerto Rico?

No. Puerto Rico is a US commonwealth, so the trip is domestic. You do not need an import permit, a CDC dog form, or a USDA-endorsed export certificate. You do need an interstate health certificate from an accredited vet plus current rabies.

Is there a quarantine for pets entering Puerto Rico?

No. There is no arrival quarantine for a dog or cat entering with its owner, as long as the health certificate, rabies, and parasite-treatment requirements are met.

How recent does the health certificate need to be?

Most sources cite within 10 days of travel, with the certificate valid for up to 30 days from inspection. Some airline desks reference a tighter pre-arrival window, so confirm the exact cutoff with your airline and book the vet visit close to departure.

Why might my dog get blocked from flying in summer?

Airlines impose heat embargoes, often around 85 degrees Fahrenheit, that stop live-animal cargo when it is too hot at departure, connection, or arrival. San Juan is hot much of the year, so summer cargo bookings are frequently embargoed. Cabin travel is less affected.

How much does it cost to bring a pet to Puerto Rico?

A small pet in the cabin costs roughly $125 to $150 each way plus vet paperwork. A professional door-to-door shipper commonly runs $900 to $2,000 or more depending on your pet's size and route. Always get a written quote.

Can a large dog fly to Puerto Rico?

Yes, but options are limited. Many major airlines restrict pet cargo to military and government moves, so a large dog usually needs a dedicated cargo carrier like Amerijet or a professional pet shipper that manages the heat window and paperwork.

What do I need to bring a cat to Puerto Rico?

The same domestic requirements as a dog: an interstate health certificate, current rabies for cats four months and older, a parasite treatment noted on the certificate, and ID. Most cats fit the in-cabin carrier limit, so they avoid the cargo and heat issues.

Does my pet need a microchip?

An ISO 15-digit microchip is strongly recommended and is the cleanest form of official ID. Some sources accept a collar with a metallic ID tag as a minimum, but a microchip is the safer choice for travel.
