Moving a pet to the United States is not one booking and one certificate. It is a chain of requirements involving the country of departure, U.S. federal agencies, the destination state, the airline and your pet’s individual health and travel needs.
The safest approach is to work backwards from the intended arrival date and verify every layer before buying a nonrefundable ticket. Rules differ for dogs and cats, and dogs may face additional requirements based on where they have been during the six months before entry.
Start with four separate rulebooks
- U.S. federal entry rules. CDC and USDA requirements depend on the animal, origin and recent travel history.
- Destination state rules. A state may require a health certificate, rabies record or other documentation in addition to federal requirements.
- Departure country rules. Export permits, government veterinary endorsements or health certificates may be required before the animal can leave.
- Airline rules. The airline decides which animals it will carry, the route, crate specifications, temperature limits and whether travel is in cabin, as checked baggage or as cargo.
Meeting one layer does not prove that the others are satisfied. Keep a written checklist showing the source, requirement, deadline and responsible person for each item.
Dogs entering the United States
CDC requires a Dog Import Form for each dog entering the United States. The applicable path also depends on whether the dog has been in a country classified as high risk for dog rabies during the previous six months and where the rabies vaccination was administered.
Current baseline requirements include that the dog appears healthy on arrival, is at least six months old and has a detectable microchip. Dogs arriving from high risk countries can need additional vaccination records, certification, testing or arrival arrangements. USDA may also apply requirements linked to animal diseases such as screwworm or foot-and-mouth disease.
Use the CDC online tool for the dog’s exact situation. Do not assume that a rule followed for a previous trip still applies.
Cats and other pets follow different paths
Cats are not covered by the CDC dog import process. CDC does not generally require a rabies vaccination certificate for cats entering the United States, but cats must appear healthy and a destination state or airline may impose additional requirements. USDA rules may also be relevant depending on origin and species.
Birds, reptiles and unusual pets can involve USDA, U.S. Fish and Wildlife Service, CITES or other controls. Confirm the species rules before making any travel commitment.
Build a pet travel timeline
As soon as the move becomes likely
- Confirm the species, breed, age, microchip details and vaccination history.
- List every country the pet has visited during the relevant lookback period.
- Check CDC, USDA, destination state and departure country requirements.
- Ask the preferred airline which routes can accept the pet.
- Identify a veterinarian experienced in international documentation.
Before booking
- Confirm whether the pet can travel in cabin, as baggage or as manifest cargo.
- Check breed, age, aircraft and seasonal temperature restrictions.
- Verify the crate standard and measure the animal correctly.
- Check whether a transit country creates another set of entry or handling rules.
- Confirm which airport can process the pet’s specific entry pathway.
During the document window
Some certificates, examinations and treatments must fall within a specific period before travel. Ask the veterinarian to build a dated schedule. Confirm whether a government veterinary authority must endorse a certificate after the private vet completes it.
The crate is part of the safety plan
Use an airline and route approved travel crate that allows the pet to stand naturally, turn around and lie down. Introduce the crate well before travel. Feed meals or treats in it and build calm, positive time inside rather than making the flight the first long confinement.
Attach identification and required documents in the manner requested by the airline. Avoid loose objects that could create a hazard. Ask the airline exactly what water container, bedding and labeling it accepts.
Do not sedate without specific veterinary advice
Sedation can affect breathing, balance and temperature regulation. Airlines may restrict sedated animals. Discuss anxiety and any medication with the treating veterinarian and follow the airline’s current policy. A familiar crate and gradual preparation are often safer parts of the plan.
Plan the route, not only the flight
A direct flight may reduce transfers and handling, but it is not always available. If a connection is necessary, check who is responsible for the pet during transit, whether the animal changes terminals or carriers and whether the transit country requires documents even when the pet does not formally enter.
Consider weather at departure, connection and arrival airports. Extreme heat or cold can cause an airline to refuse carriage even when every document is correct.
Prepare for arrival
- Carry paper and electronic copies of every record.
- Know where the pet will be collected and inspected.
- Arrange pet-friendly transport that can accommodate the crate.
- Book pet-friendly accommodation and confirm size or breed rules.
- Identify a local veterinarian before arrival.
- Keep the first few days calm and watch for dehydration, illness or severe stress.
Budget beyond the airfare
Costs can include microchipping, vaccinations, laboratory tests, veterinary visits, government endorsements, import or export permits, the crate, ground transport, airline handling, cargo agents, inspection facilities, boarding and professional relocation support. Build a contingency for a route change or document that must be repeated.
Common mistakes that cause delays
- Using an outdated blog or airline page as the only source.
- Checking the destination but not the transit country.
- Booking a flight before the airline confirms pet capacity.
- Getting a vaccination or certificate in the wrong sequence.
- Assuming the same paperwork applies to every pet in the family.
- Failing to check the destination state’s requirements.
