Does my pet need a health certificate to fly? Quick answer: Most airlines and every international destination require a pet health certificate, officially called a Certificate of Veterinary Inspection (CVI), issued by a licensed veterinarian within 10 days of travel. Domestic flights sometimes accept an airline-specific form instead, but international travel almost always requires a USDA-accredited veterinarian and, in many cases, USDA APHIS endorsement. The United States does not issue pet passports, so the health certificate is the official substitute.
PetWorks is a nationwide pet care services marketplace connecting pet parents with vetted transport professionals who handle this paperwork every day, and getting the certificate right the first time avoids delays at the airport or the border. This guide is part of PetWorks’ International Pet Shippers coverage for pet parents planning cross-border travel.
What a Pet Health Certificate Actually Covers
A health certificate confirms a licensed veterinarian examined the pet and found it fit to travel. Per USDA APHIS pet travel guidance, it may also confirm rabies vaccination status, parasite treatment, and microchip verification, depending on the destination. Certificates are only issued after the vet examines the pet and verifies or performs any required testing and vaccinations.
Domestic vs. International Requirements
| Domestic Flights | International Flights | |
|---|---|---|
| Who issues it | Any licensed veterinarian (airline-dependent) | USDA-accredited veterinarian |
| USDA endorsement | Not required | Often required, depending on destination |
| Typical validity window | Usually within 10 days of travel | Usually within 10 days of travel |
| Standard document | Airline health form or CVI | Country-specific USDA health certificate |
There is no single standard health certificate, since each destination country sets its own requirements based on the type of pet traveling. Pet parents should confirm requirements with both the airline and the destination country well before booking.
Don’t Forget the Return Trip: Updated CDC Entry Rules Obtaining an international health certificate gets your pet out of the country, but returning home to the United States requires adherence to federal import regulations. All dogs entering or re-entering the U.S., even on short vacations – must be at least 6 months old, microchipped with an ISO-compatible chip, and accompanied by a receipt for the mandatory CDC Dog Import Form. Depending on whether your itinerary includes a rabies high-risk country, returning dogs may also require a USDA-endorsed Certification of U.S.-Issued Rabies Vaccination completed before departing the states. Double-checking both entry and return documentation prevents unexpected delays or quarantine issues at border control.
Is a Health Certificate the Same as a Pet Passport?
No. Because entry requirements vary by country, the United States does not issue pet passports for international pet travel. The health certificate serves the same function: it proves the pet meets the destination’s entry rules.
When to Start the Process
International health certificates typically need to be issued close to the travel date, often within a 10-day window before departure, and USDA endorsement can add processing time. Pet parents should begin the process as soon as they know their pet will be traveling internationally, since some countries require weeks or months of advance preparation for vaccinations and testing.
For pet parents who want the paperwork handled start to finish, PetWorks connects with vetted international pet shipping professionals who manage health certificates, USDA endorsement, and airline compliance as part of the booking.

Vet-Reviewed Insight
“Pet parents often underestimate how quickly the paperwork window closes. A health certificate issued too early or too late can ground a trip. I always tell owners to loop in their veterinarian the moment a travel date is set, not the week before.” – Dr. Marty Goldstein, DVM
