Your dog needs a receipt to come home, and no, it’s not for the souvenir squeaky toy. The receipt arrives by email, and if anything on the paperwork is off, the airline can deny boarding right at the counter. Nine rules decide whether the trip home goes smoothly, and the check-in line is a bad place to learn them.
The 6-Month Lookback
Your dog’s rules depend on every country it visited in the past six months, not just the place you flew home from. Dogs that spent time in any high-risk country must be vaccinated against rabies to enter. If a country is not on CDC’s high-risk list, CDC does not treat it as high risk.
The Health Certificate That Stopped Counting
If your dog was vaccinated in the U.S. and visited a high-risk country, a newly issued export health certificate will not get it back in. Certificates issued after July 31, 2025 are not accepted for re-entry. You need CDC’s U.S.-issued rabies vaccination form, completed by a USDA-accredited veterinarian and endorsed by USDA before your dog leaves the U.S. It is not the standard rabies certificate used for local registration.
A Microchip That Scans
Every dog needs a microchip that a universal scanner can detect. For high-risk-country travel, timing matters too. CDC says the chip must be implanted before the rabies vaccination used for entry. A vaccine given first does not count for the import paperwork.
12 Weeks and 28 Days
Dogs that have been in a high-risk country cannot use an initial rabies vaccine given before 12 weeks of age. The U.S.-issued rabies form generally cannot be completed until at least 28 days after that first vaccine. A booster can count immediately for a dog over 15 months old when an earlier qualifying vaccine is documented and coverage did not lapse.
Puppies Under 6 Months
Your dog must be at least six months old when it enters or returns to the U.S. A dog that misses the age minimum can be denied admission and returned to the country of departure. For dogs under one year old coming from a high-risk country, CDC says the form photo should be taken within 15 days before travel.
One Receipt for Each Dog
Every dog needs its own CDC Dog Import Form receipt, even when several dogs travel together. For a dog that has been in a high-risk country, the receipt is valid for one entry and only on the arrival date shown. You can print it or keep it on your phone.
6 Months, 1 Country
Frequent trips between the U.S. and Canada or Mexico can use one receipt for multiple entries for six months if the dog has been only in rabies-free or low-risk countries. The receipt still covers travel from the country named on the form. Return from France instead, and you need a new form listing France.
The Port Printed on Your Form
Dogs that have only been in rabies-free or low-risk countries can use any airport, seaport, or land border crossing. Properly documented U.S.-vaccinated dogs returning from a high-risk country can also use any port, but the location must match the CDC receipt. Foreign-vaccinated dogs from high-risk countries normally must arrive by air at the airport tied to a CDC-registered animal care facility. CDC allows qualifying foreign-vaccinated service dogs traveling with the person they assist to arrive by sea.
What the Airline Checks at the Counter
Airlines check required paperwork before a dog boards for the U.S. CDC tells carriers to confirm the dog appears healthy and at least six months old, has a microchip, and has a Dog Import Form receipt. High-risk-country dogs need the additional documents that match their vaccination status. Missing required paperwork can mean denied boarding.
Your Dog’s Paper Trail Starts Before You Pack
The airport is the wrong place to discover that a vaccine date or form will not work. Several key requirements are settled at the vet’s office before your dog leaves the U.S., which makes the return trip worth planning first. Check CDC rules again shortly before departure because requirements can change.
