Dog travel paperwork has an awkward shape: for most trips nobody asks for anything, and then one trip asks for four documents you do not have. The fix is to build the folder once rather than researching it per trip. This page is the index - what goes in the folder, and which kind of journey actually asks for each item. Where a document has real mechanics behind it, like a health certificate's validity window, we point at the page on this site that owns it rather than repeating a half version here.
The single most important line on this page: a rabies vaccination certificate is the document that does the most work. It is what Canada asks for at a land border, what a boarding kennel asks for, what a vet in another state asks for, and what an airline asks to see alongside a health certificate. If you build nothing else, get a current one that clearly identifies your specific dog - breed, colour, markings, microchip number - rather than one that could describe any dog of that size.
The folder
1. Rabies vaccination certificate
Original, signed by a licensed veterinarian, identifying the dog. Check the expiry covers your whole trip including the return. This is the backbone of the folder.
2. Microchip number, written down
Not just "the dog is chipped" - the actual number, plus the registry and your login. Two reasons: a border or a shelter needs the number, and a chip whose registry still lists a phone you had three years ago is a chip that does nothing. Verify the registry details before every significant trip. Our microchip versus GPS tracker comparison explains why the chip is the legal identity and the tracker is the search tool.
3. Health certificate, when the trip needs one
A veterinary health certificate - often a Certificate of Veterinary Inspection - is issued within a limited window before travel, which is the detail that catches people: get it too early and it expires mid-trip. Airlines are the usual requester. The mechanics, the timing and who can issue one are on dog health certificates to fly.
4. Photographs, on paper as well as on your phone
A clear current photo of the dog, and one of you with the dog. The second is the one people skip and the one that proves ownership when a dog has been found by somebody reluctant to hand it over. Print them, because a dead phone is exactly when you need this.
5. Veterinary records and medication details
Current medications with doses, any conditions, and your own vet's phone number. Carry prescription medication in its labelled original packaging. Look up a vet near your destination before you go rather than searching while something is wrong.
6. Proof of ownership, for longer or international trips
Adoption paperwork, registration, or vet records in your name. Rarely requested, awkward to produce from a hotel room.
7. The CDC Dog Import Form, for any trip that leaves the country
Since 1 August 2024 this applies to dogs returning to the United States, not just arriving - including your own US dog coming back from a weekend in Canada. It comes with a microchip requirement and a six-month minimum age. The full version, with the land-border specifics, is on driving to Canada or Mexico with a dog, and the air version is on flying internationally with a dog.
What each trip actually asks for
| Trip | Usually asked for | Carry anyway |
|---|
| Road trip, in-state | Nothing | Rabies certificate, microchip number, photos |
| Road trip, across state lines | Nothing at the line; vets and kennels will ask | Rabies certificate, vet records |
| Domestic flight, in cabin | Airline paperwork, often a health certificate | Rabies certificate, microchip number |
| Flight in cargo | Health certificate, airline-specific forms | Everything in the folder |
| Amtrak | You certify vaccinations are current when booking | Rabies certificate |
| Hotel or vacation rental | Pet policy and fee; occasionally vaccination proof | Rabies certificate |
| Canada or Mexico by car | Rabies certificate out; CDC Dog Import Form back | Everything, plus microchip verified |
| International flight | Destination-specific, often months of lead time | Everything, started early |
Two rules that save the trip
Photograph the whole folder and store it offline. Not in a browser tab, not in an email you need signal to open. A folder on your phone that works at a land border with no service, plus paper originals in a bag. Re-read the official requirements two weeks out. Every rule on this page comes from a government or a company that can change it without telling you, and the 2024 CDC change is the proof - a lot of people found out at a border.
