Guide to Traveling to Mexico with Your Dog or Cat | 9-Month Preparation Process [2026 Edition]

Last Updated: July 29, 2026

Why do I need nine months to prepare for a trip to Mexico?

The length of the preparation period is determined not by the hurdles involved in entering Mexico itself, but byProcedures for returning to Japan afterwardThat's right. The legal requirements for entering Mexico are not as strict as those of many other countries.

According to the Animal Quarantine Service’s classification, Mexico is not included in the “designated regions” for import quarantine and is treated as a country outside the designated regions. Returning from a country outside the designated regions requires several procedures. The animal must be microchipped, receive two doses of the rabies vaccine, and undergo a rabies antibody titer test. By ensuring an interval of at least 180 days between the blood draw date and arrival in Japan, you become eligible for a route that allows you to avoid prolonged quarantine at the airport (Source: Animal Quarantine Service: "Procedures for Importing Dogs, Cats, and Other Animals (From Areas Other Than Designated Regions)"(as of July 2026). These 180 days may be accumulated while staying in Mexico; it is not necessary to complete the entire period before leaving Japan. However, if the 180-day period has not been completed by the time you arrive in Japan, your pet will be subject to a quarantine period of up to 180 days at an animal quarantine station.

A 9-Month Preparation Schedule: What Needs to Be Done by When?

Considering the 180-day waiting period and the deadlines for various documents, it’s best to start preparing nine months before departure to allow plenty of time. The following is a recommended schedule provided by PetAirJPN; it does not represent the exact deadlines set by law. The actual timeline may vary depending on your pet’s age and the status of your document preparation.

In what order should microchipping, vaccinations, and antibody titer testing be performed?

For customs procedures when returning to Japan, the order of these three steps is important. As a general rule, rabies vaccinations or tests conducted before the microchip is implanted will not be recognized as valid. While they may be accepted under certain conditions, please check with the Animal Quarantine Station to confirm whether they are valid in your specific case. If you are unsure, be sure to start by having the microchip implanted.

What should you keep in mind when choosing an airline?

Avoid assuming that a particular airline will be able to transport your pet just based on its name. This is because whether an airline accepts pets—especially dogs and cats—for cargo transport varies significantly from airline to airline and depending on the time of year.

Some airlines operate direct flights between Japan and Mexico. However, routes and schedules vary depending on the time of year, and it is not uncommon to have to take a connecting flight. Whether you’re taking a direct or connecting flight, the things you need to check remain the same. Whether your planned flight accepts pets in the cargo hold is a separate matter, so be sure to check the airline’s official website.

International Air Transport Association (IATA)While there are general guidelines in place, the actual decision on whether to accept pets and the conditions for doing so are left to the discretion of each airline. Some airlines have suspended the acceptance of pet cargo for general passengers for an extended period.

Before making a reservation, be sure to check the official website of the airline you’re considering to confirm its current pet transport policies, restrictions on dog breeds, crate size requirements, and any seasonal restrictions. Since some airlines restrict pet transport during periods of high temperatures, such as the summer, it’s a good idea to check early to see if there are any regulations that apply to your planned travel dates.
