Can You Ship a Pet? What USPS, Airlines, and USDA Actually Allow

Yes, you can ship a pet, but only through specific, regulated channels: airline pet programs (cabin, checked baggage, or manifest cargo) and licensed ground or air pet relocation services. You cannot ship a dog, cat, or other household pet through the United States Postal Service (USPS), FedEx, or UPS. Each shipping method has its own age, health, crate, and documentation rules set by government agencies and airlines, and the requirements differ sharply for domestic versus international trips.

This guide breaks down who actually allows pet shipping, what the rules require in 2026, what it costs, and where a livestock-specific identity product like Animal Passport fits (and does not fit) into this picture.

Can you ship a pet? The short answer by carrier type

Whether you can ship a pet depends entirely on which "shipper" you mean. Mail and parcel carriers say no. Airlines and professional relocation companies say yes, under conditions.

Why you can't mail a pet

USPS Publication 52 states plainly that "warm-blooded animals, except for adult birds and specified day-old birds under the specific conditions in this section, are not mailable," a category that explicitly includes dogs, puppies, cats, and kittens (USPS, Publication 52, Section 525). FedEx and UPS apply similar restrictions in their own shipping policies, permitting only categories like fish, worms, and select reptiles or amphibians for general consumer shipments, not household pets. If you see an online listing offering to "ship" a puppy through a parcel carrier, treat it as a red flag: legitimate transport of a dog or cat in the U.S. happens through airlines or dedicated pet transport companies, not postal or parcel networks.

Shipping a pet by air: cabin, baggage, and cargo

Airlines move pets three ways: in the cabin under the seat, as checked baggage, or as manifest cargo in a temperature-controlled hold. The International Air Transport Association (IATA) publishes the Live Animals Regulations (LAR), describing it as "the worldwide standard for transporting live animals by commercial airlines," with the current edition effective January 1, 2026 (IATA, 2026). The LAR sets minimum standards for crate construction, ventilation, labeling, and handling, but individual airlines layer their own rules on top, including seasonal temperature embargoes and breed restrictions.

IATA notes that cargo-hold travel is a legitimate, safe option for pets too large for the cabin: "cats and dogs actually travel better this way because it is quieter and they will rest in a darkened environment," adding that "millions of animals are carried safely every year" this way (IATA, Traveling with Pets). At the same time, IATA is explicit that airlines are not obligated to carry live animals, and many have added their own restrictions, most notably around brachycephalic (flat-faced) breeds such as bulldogs and Persian cats, which face a higher risk of breathing problems and heat stress in transit and are banned from cargo holds by some carriers entirely.

Minimum requirements for air-shipped pets

1. Age: IATA's baseline requires animals to be at least eight weeks old and fully weaned before air travel.
2. Crate: An IATA-compliant container sized so the pet can turn around, stand, sit, and lie down naturally.
3. Health documentation: A veterinary health certificate, and for international trips, USDA endorsement.
4. Airline-specific approval: Confirm breed, size, and route restrictions directly with the carrier before booking, since IATA standards are a floor, not a guarantee of acceptance.

Domestic commercial pet transport: what the law requires

In the United States, any commercial carrier or intermediate handler that transports dogs or cats must comply with the Animal Welfare Act's transportation standards under 9 CFR Part 3, Subpart A, enforced by the United States Department of Agriculture (USDA). These regulations, in force since 1991, require that no animal in obvious physical distress be transported, that live animal shipments not be commingled with inanimate cargo, and that carriers continue feeding, watering, and housing dogs and cats until the consignee accepts delivery. This is the regulatory floor for any professional pet shipping or relocation business operating in the U.S., separate from airline-specific policy.

Shipping a pet internationally: USDA, CDC, and destination rules

International pet shipping adds government paperwork on both ends. The USDA's Animal and Plant Health Inspection Service (USDA APHIS) oversees export health certification for pets leaving the U.S., requiring an APHIS-accredited veterinarian to complete and, in many cases, have USDA endorse the health certificate before departure. Requirements on arrival vary by destination and can include microchipping, rabies titers, blood tests, and import permits.

Coming into the U.S., the Centers for Disease Control and Prevention (CDC) regulates dog imports based on the exporting country's rabies risk classification. Dogs from countries the CDC classifies as high-risk for rabies generally need a valid rabies serology titer to avoid a 28-day quarantine at a CDC-registered animal care facility, while a CDC Dog Import Form receipt is required more broadly. Multiple industry sources reviewing 2026 policy also note a minimum age requirement (commonly cited as six months) and a rule that the microchip must be implanted before the rabies vaccination is given, since the vaccination record is tied to that specific chip number.

Don't confuse an EU pet passport with a livestock ID product

The European Commission's pet travel rules for the EU are a separate, government-issued system, not a private product. Under the EU's non-commercial pet travel framework, a dog, cat, or ferret must have an ISO-compliant microchip, a rabies vaccination given by an official or authorized veterinarian, and a passport document (following the EU's standard model) that records the microchip code, vaccination details, and owner information, and the pet must travel with its owner under the owner's direct responsibility (European Commission, Food Safety, "Travelling with a pet within the EU"). This is the official EU pet passport, tied to a specific regulatory framework the Commission has been updating for 2026, and it is what airlines and EU border officials check for pets, not a substitute for it.

Animal Passport is a different kind of product for a different use case. It is a phone-based, muzzle-biometric digital identity record, primarily built for livestock rather than companion-animal air travel: it captures a nose print (unique like a human fingerprint), links it to an owner, breed, and vaccination history, estimates age from a dental photo with a confidence score, and scores body condition (1-5) from a side-profile photo. It is not a government-issued travel document, does not replace an EU pet passport, USDA export certificate, or CDC import form, and should not be treated as one. Where it has demonstrated real-world value is identity recovery after paper records fail, as in the flood-hit livestock rescue response in Pakistan in August 2025, when farmers used biometric identity to reclaim animals after paper ear tags had washed away.

What it costs to ship a pet

Cost depends heavily on distance, pet size, and destination-country requirements. Multiple pet relocation industry sources place international shipping in the range of roughly $1,000 to $5,000 or more per pet, with simpler routes for small-to-medium pets often landing between $2,000 and $4,000, and long-haul or complex international relocations reaching $4,000 to $8,000+. Destinations with strict import controls or quarantine requirements, such as island nations, tend to sit at the higher end. On top of airline cargo or relocation-company fees, budget for an IATA-compliant crate (commonly $100-$600), and veterinary health certificates, vaccinations, and any required blood tests or titers (commonly $200-$1,000+), since these are typically billed separately from the transport fee itself.

Step-by-step: how to ship a pet the right way

1. Confirm your pet is old enough and healthy enough to travel — most air carriers use IATA's eight-week minimum as a floor, and many require pets to be older for international trips.
2. Choose your channel — book directly with an airline's pet program, or hire a licensed pet relocation company that manages paperwork end to end.
3. Get an IATA-compliant crate sized for your pet to stand, turn, and lie down naturally.
4. Schedule vet visits early for microchipping, rabies vaccination, and any titers your destination requires, since some countries require a waiting period (commonly a multi-month wait) after vaccination before travel.
5. Obtain and endorse health certificates through an APHIS-accredited veterinarian for U.S. exports, or the equivalent authority at origin.
6. Check breed- and airline-specific restrictions, especially for brachycephalic breeds, which many carriers restrict or refuse in cargo holds.
7. Reconfirm requirements close to travel, since rules for both the U.S. (CDC/USDA) and destinations like the EU have changed on a rolling basis through 2026.

FAQ: Can you ship a pet?

Can I ship my dog through USPS?

No. USPS Publication 52 classifies dogs, puppies, cats, and kittens as nonmailable warm-blooded animals, so USPS does not accept them for shipment under any mailing class.

Can I ship a pet with FedEx or UPS?

No, not as a general consumer. Both carriers restrict live-animal shipments to categories like fish, worms, and select reptiles or amphibians, and do not transport household pets such as dogs or cats for individual customers.

Is it safe to ship a pet as air cargo?

IATA states that cargo holds are a safe, commonly used option and that "millions of animals are carried safely every year" this way, but safety depends on following IATA's Live Animals Regulations, using a compliant crate, and choosing an airline route without extreme temperatures, since some carriers apply seasonal heat or cold embargoes on live-animal cargo.

How much does it cost to ship a pet internationally?

Industry estimates commonly range from about $1,000 to $5,000 or more per pet, depending on destination, pet size, crate cost, and required veterinary procedures, with strict-entry destinations like island nations sometimes exceeding $8,000.

Do all airlines accept pets as cargo?

No. IATA confirms airlines are not obligated to carry live animals, and many apply their own breed restrictions and seasonal embargoes on top of the baseline IATA standards, so acceptance must be confirmed directly with each carrier.

Is an EU pet passport the same as Animal Passport's digital ID?

No. An EU pet passport is an official government document verifying microchip and rabies status for dogs, cats, and ferrets traveling within the EU, while Animal Passport is a separate phone-based biometric product using muzzle (nose print) ID, primarily for livestock identity, not a government travel document.

What documents do I need to bring a dog into the United States?

Requirements depend on the dog's recent country history; most need a CDC Dog Import Form, and dogs from CDC-classified high-risk rabies countries generally need a valid rabies serology titer to avoid a 28-day quarantine.

Can I ship a pet without flying with it myself?

Yes. Licensed pet relocation companies and airline manifest-cargo programs handle unaccompanied pet travel, managing crate compliance and paperwork, though the owner is still responsible for meeting destination entry requirements.
