Bringing a dog to Mexico in 2026
Last updated: September 24, 2026: verified against Mexican animal health requirements (SENASICA) and US CDC guidance for dogs returning from Mexico.
Mexico looks simple from the outside, and for the outbound trip it mostly is: a health certificate and a rabies vaccination certificate. The part people get wrong is the timing of the vaccine, and the fact that the return to the USA is governed by a stricter rule than the trip out.
Two documents, and a clock
Mexico asks for a health certificate and a rabies vaccination certificate. The vaccine has a timing window: at least 15 days before entry, and no more than a year old.
Certificate + rabies, 15 days minimum
What Mexico asks for
Mexico does not quarantine personal pets, but it does check two things at the border: a health certificate and proof of rabies vaccination. Cats and dogs both fall under the same general rule.
- Health certificate: A health certificate (certificado de salud) issued by a licensed veterinarian, certifying the animal is free of infectious and contagious disease and fit to travel. It is generally expected to be recent, so have it drawn up close to the travel date.
- Rabies vaccination: A rabies vaccination certificate showing the vaccine was given at least 15 days and not more than 1 year before entry. Mexico treats rabies as the single most important requirement, because the country is actively working to keep dog rabies out.
- Microchip: A microchip is not universally demanded for personal pets at the land border, but it is increasingly expected, and it is what links the animal to the vaccination record. Have it in place and readable.
- Inspection on arrival: Mexico may inspect the animal at the point of entry, and the officer can require the certificate to be presented in person. Carry the originals, not photocopies.
The trap almost nobody plans for: the way back
The return leg matters more than the outbound one. A dog that has been in Mexico is coming back from a country the CDC does not treat as dog-rabies-free, so the CDC Dog Import Form rules for high-risk countries apply, not the simple receipt-only route.
Puppies under 3 months cannot be vaccinated against rabies, so they cannot meet the rabies requirement. Plan around this: a puppy that young cannot travel to Mexico on the standard personal-pet route.
What it costs
- Vet health certificate in your country, at your vet's rates.
- Rabies vaccination, if it is not already up to date.
- No import permit fee for a personal pet.
- CDC Dog Import Form on the return to the USA: free, one form per dog.
Frequently asked questions
Do I need a permit to bring a dog to Mexico?
No import permit is required for a personal pet. Mexico checks a health certificate and proof of rabies vaccination at the border.
How long before travel must the rabies vaccine be given?
At least 15 days and no more than 1 year before entry. A vaccine given the day before travel is not valid.
Can I bring a puppy under 3 months to Mexico?
No, not on the standard personal-pet route. Puppies under 3 months cannot be vaccinated against rabies, so they cannot meet the rabies requirement.
What documents do I need to take my dog from the USA to Mexico?
A health certificate from a licensed veterinarian and a rabies vaccination certificate. Carry the originals, because the officer at the point of entry can ask to see them in person.
What do I need to bring my dog back to the USA from Mexico?
More than you need going out. Mexico is not a dog-rabies-free country for CDC purposes, so the CDC Dog Import Form rules for dogs that have been in a high-risk country apply to the return leg, not the simple receipt-only route.
