New Dog Entry Requirements in Mexico: What Tulum Residents Need to Know

Key takeaway: Dogs entering Mexico now require a New World Screwworm Inspection Certificate, adding a new step to the process.

What's Changing

On August 3, 2026, the rules for bringing a dog into Mexico from the United States underwent significant changes. The New World screwworm inspection has become mandatory, requiring a new certificate to be completed by a USDA-accredited veterinarian. This new requirement adds a layer of complexity to the pet travel process, but it is still relatively straightforward for residents and visitors.

What It Means for Residents

The change affects Tulum residents and expats who frequently travel across the border with their pets. It is important for them to plan ahead and ensure they have all the necessary documents. The five-day window before the trip is crucial, as the certificate must be issued no later than five days before the dog's arrival at the Mexican port of entry.

For those who are bringing a dog to Mexico for a move or a longer stay, the process has become slightly more complicated. However, the trip is still simple, just requiring a different form now. It’s essential to check the latest requirements to avoid any last-minute hassles.

Practical Tips for Pet Owners

When flying into Mexico, every pet must be inspected at the port of entry by SENASICA. The process is similar to what has been used in the past, with passengers requesting a Certificado Zoosanitario de Importación from SENASICA staff at the counter. The certificate is issued after a visual inspection of the pet and the carrier.

For Tulum residents, it is advisable to have a list of 24-hour veterinary clinics, as emergencies can happen at any time. Clinics like 'The Jungle' and 'The Pet Experience' offer extended hours and emergency care, making them a valuable resource for pet owners.

When traveling with pets, it’s also important to consider the airline fees. Both Aeromexico and Volaris charge by the segment, with a maximum combined weight for the pet and carrier in the cabin. If the pet exceeds this limit, it will need to travel in cargo, which can be costly and time-consuming to arrange.

Return Trip Requirements

When taking a pet back to the United States, the rules are split between the CDC and USDA. The CDC requires a rabies vaccination certificate, while the USDA may require a New World screwworm inspection certificate. It is essential to check both sets of requirements to ensure a smooth return journey.
