Relocating a pet to the United States is a project with several decision-makers: the departure country, transit countries, U.S. federal agencies, the destination state, the airline and your veterinarian. A booking can fail even when one set of rules has been satisfied, because every layer must work on the same travel date.
This guide focuses on the planning timeline. For a detailed explanation of the current federal rules, also read Bringing Your Pet to the USA.
Start with the animal’s complete route and recent travel history. The destination alone is not enough.
Build the route before buying the ticket
Write down the exact journey:
- Species, breed, age, weight and health
- Country of departure and every country visited in the previous six months
- All transit airports and whether the animal leaves the secure transit area
- U.S. port of entry and final destination state
- In-cabin, accompanied baggage or manifest-cargo travel
- Proposed dates and temperatures at every airport
- Who is legally importing and collecting the animal
A direct route is often easier to manage than a cheaper itinerary with multiple connections. Long layovers, self-transfers, overnight stops and airline changes can add paperwork, handling risk and transit-country requirements.
Understand the four rulebooks
- Departure-country rules: Export permits, government veterinary endorsement, health certificates or pre-export examinations may apply.
- U.S. federal rules: CDC and USDA APHIS requirements depend on the animal and travel history.
- State rules: The destination state may require vaccination records, a health certificate, testing or other documents.
- Airline rules: Each carrier sets its accepted breeds, routes, crate standards, booking windows and temperature restrictions.
USDA APHIS makes clear that pet owners are responsible for meeting both federal and state requirements. Start with its pet import guidance, then check the official agriculture or animal-health site for the destination state.
Dogs need a CDC-specific check
CDC requirements depend heavily on where the dog has been during the six months before U.S. entry and where its rabies vaccination was administered. All dogs entering the United States need a CDC Dog Import Form receipt. CDC also requires dogs to appear healthy on arrival, be at least six months old and have a detectable microchip.
Use the official CDC Dog Importation Navigator for the animal’s exact circumstances. The Dog Import Form instructions explain that a separate form is required for each dog.
If a dog has been in a country classified by CDC as high risk for dog rabies during the previous six months, extra vaccination, microchip, document, testing, port or facility requirements may apply. Check the live CDC high-risk country list. Do not rely on the country’s status from a previous move.
Cats follow a different federal path
USDA APHIS currently states that its Veterinary Services division has no animal-health requirements for importing a domestic pet cat from another country. That does not mean a cat travels without rules. CDC may inspect cats that appear ill, the destination state can impose requirements, the departure country may require export documents and the airline will have its own conditions.
Check the current USDA guidance for importing cats. Birds, rabbits, reptiles and other animals have separate agency and disease-control rules and should not be planned from a dog or cat checklist.
Twelve or more weeks before travel
- Confirm that the pet is eligible for the route and carrier.
- Check departure, transit, federal and state requirements.
- Ask a veterinarian to review vaccination, microchip and health records.
- Identify any testing or waiting periods that control the schedule.
- Compare direct and connecting routes, including seasonal restrictions.
- Measure the pet and obtain the correct travel crate.
- Request written quotes showing transport, handling, veterinary and government costs separately.
Do this earlier for a high-risk-country dog, an older animal, a snub-nosed breed, a pet with a medical condition or a route requiring cargo and several agencies.
Six to eight weeks before travel
Begin crate training gradually. The crate should become a familiar resting place, not an object introduced on departure day. Feed treats or meals inside it, practise short closed-door periods and build toward calm time at the expected travel duration.
Confirm the airline’s current crate measurements and hardware. A crate that is marketed as “airline approved” can still be rejected if the size, ventilation, fasteners, water bowls or construction do not meet that carrier’s requirements.
Prepare a single digital and paper file containing:
- Microchip record
- Rabies and other vaccination certificates
- Laboratory results where required
- Health and export certificates
- CDC form receipt and supporting documents
- Airline booking and crate confirmation
- Owner identification and contact details
- Transit and destination approvals
- Medication and veterinary instructions
Two to four weeks before travel
Reconfirm every requirement against the live source. Check whether any certificate must be issued within a narrow number of days before travel and whether it needs government endorsement. Make veterinary appointments backward from the flight date.
Confirm who will deliver the pet, where check-in occurs, how early the animal must arrive and who can collect it in the United States. Cargo collection may happen at a separate facility rather than the passenger terminal.
Arrange pet-friendly accommodation and safe ground transport. When choosing a home or state, consider breed restrictions, landlord rules, climate, fencing, insurance and access to veterinary care. The guide to choosing a U.S. state and city can help frame the wider decision.
The final week
- Complete time-sensitive veterinary examinations and certificates.
- Check the microchip number against every document.
- Confirm the flight, weather and temperature embargo status.
- Label the crate with contact and routing information.
- Attach documents in the format required by the carrier.
- Prepare food and water according to the airline’s instructions.
- Carry duplicate records with the travelling family member.
- Keep a contingency plan for delay, rerouting or denied boarding.
Discuss anxiety and medication with the veterinarian well before travel. Do not sedate an animal simply because the flight will be stressful. The American Veterinary Medical Association advises owners to consult a veterinarian before giving tranquilizers and provides broader dog and cat travel guidance.
Travel day
Follow the veterinarian and airline instructions for feeding, water and exercise. Arrive early enough for document and crate checks without creating hours of unnecessary waiting. Photograph the pet, crate and attached documents before handover and keep the booking reference and emergency contacts accessible.
If the pet appears ill or distressed, ask the veterinarian and carrier whether travel should proceed. A missed flight is difficult; a preventable health emergency is worse.
The first 72 hours after arrival
Keep the first days quiet and predictable. Offer water, familiar food and a secure space. Expect temporary changes in appetite, sleep, toileting or behaviour, but contact a veterinarian promptly if symptoms are severe, persistent or concerning.
Then complete the local setup:
- Register with a nearby veterinarian and share the records.
- Update the microchip database with U.S. contact details.
- Obtain local licensing where required.
- Review heartworm, tick, flea and regional disease prevention.
- Check the garden, fencing, plants and local wildlife risks.
- Introduce new people, animals and environments gradually.
When a relocation specialist adds value
Professional help may be worthwhile for high-risk rabies routes, manifest cargo, multiple pets, complex transit, restricted breeds, medical needs, unusual species or a move where the family cannot travel with the animal. Ask who performs each service, which licences or agency approvals apply, how the animal is monitored and what happens if the route changes.
A specialist can coordinate the process, but the owner should still receive copies of every document and verify the official requirements.
Keep the wider move coordinated
Pet timing must fit accommodation, family flights, household shipping and the first weeks in the United States. Review shipping and moving options and what to pack so the pet plan does not sit in isolation.
Need one plan for the whole move? The New Life Journey brings pets, schooling, accommodation, state selection, financial readiness and settling into a structured roadmap. More practical guides are available in the Resource Hub.
Pet import, export, state and airline rules can change. Recheck each requirement shortly before travel and obtain case-specific veterinary or pet-relocation advice for your animal.
