No. There is no such thing as a US pet passport. The document people mean when they ask is usually one of two things: an EU pet passport, which is real but is issued only to pet owners resident in the EU, or an international health certificate, which is what a dog travelling out of the United States actually needs. The confusion is not the reader's fault - the EU genuinely calls its document a passport, and the rest of the world does not have one.
The useful answer is per trip, so here it is up front. Flying domestically:no passport, and usually no health certificate either - the airline's own pet paperwork plus current vaccinations is the realistic requirement. Leaving the United States:almost always a health certificate completed by a USDA-accredited veterinarian and endorsed by USDA APHIS, to the destination country's specification. Coming back into the United States:the CDC's rules apply to your own dog returning home, which is the part that catches people.
What an EU pet passport actually is
The European Commission defines it as "an identification document, which follows an EU standard model and is mandatory for travel between EU countries". It records the animal's identity, its microchip or tattoo code, its rabies vaccination history and the issuing vet's details, any authorised vet can issue one, and it is valid for the life of the animal as long as the health information stays current. It is a genuinely excellent system and it has one hard edge: it is issued only to pet owners resident in the EU. A passport issued to an owner resident in Great Britain stopped being valid for EU and Northern Ireland travel on 1 January 2021.
So a US-resident dog cannot get one, however many times the internet suggests otherwise. What a US dog travelling to the EU needs instead is an EU animal health certificate, issued by an official state vet in the country of departure not more than 10 days before the pet arrives in the EU. It covers identity, health and rabies status, and it stays valid for six months of onward travel inside the EU or until the rabies vaccination expires, whichever comes first.
The two timing rules underneath all of it, from the same source: the dog must be microchipped before the rabies vaccination is given, and it must be at least 12 weeks old at that vaccination, after which you must wait at least 21 days before travelling. Get the order wrong - vaccinate, then chip - and the clock starts again. That one detail ruins more trips than any form.
What your dog needs, by trip
| Trip | Is a "passport" involved? | What is actually asked for |
|---|
| Driving in your own state | No | Nothing official. Carry rabies proof and ID anyway. |
| Driving across state lines | No | Some states have interstate requirements on paper; enforcement for a pet in a car is effectively nil. Rabies certificate in the folder. |
| US domestic flight, in cabin | No | The airline's pet paperwork and fee. Many do not ask for a health certificate. |
| US domestic flight, in the hold | No | A health certificate, usually within 10 days of travel, plus a compliant kennel. |
| US to the EU | No - you cannot get the EU passport | EU animal health certificate, issued within 10 days of arrival, microchip before rabies vaccination, 21-day wait. |
| US to Canada or Mexico by road | No | Destination paperwork plus the CDC's requirements for the return leg. See our land-border guide. |
| Returning to the US | No | CDC Dog Import Form and the current CDC entry conditions - these apply to US dogs coming home, not only to imports. |
Requirements change, by country and by month, and the only authority that counts is the destination's own. Start at USDA APHIS Pet Travel, which publishes the country-by-country requirements for animals leaving the US, and read the CDC's dog importation pages for the way home. We link both below rather than copying their tables, because a stale copy of a government table is worse than no copy.
The folder that answers every version of the question
Whatever the trip, the same small stack of paper covers it, and the reason to assemble it is not the border - it is the vet 400 miles from home who has never met your dog. Keep one folder with: the rabies certificate; the microchip number and the registry it is registered with; a current vaccination record; your vet's contact details; any health certificate for this trip; and a photograph of the dog that actually looks like it. Our travel documents checklist is the printable version of that, and the health certificate page explains the validity window in detail, which is the piece most people get wrong.
One more thing that is not paperwork but functions like it: a microchip is only as good as the registry entry behind it. If you have moved house since the dog was chipped, the number in the dog points at an address you do not live at. Check it at the Pet Microchip Lookup before a big trip - it takes a minute and it is the single highest-value five minutes of trip admin there is.
