Can I travel with my pet from United States to Mexico? Yes. Companion dogs and cats can enter Mexico from United States under non-commercial regulations established by National Service of Agro-Alimentary Public Health, Safety and Quality (SENASICA) (Mexican Federal Animal Health Law & SENASICA Official Notice B00.02.01.01.01). Entry requires an ISO 11784/11785 microchip, rabies vaccination with a current vaccine waiting period, exempt / not required, and an endorsed Rabies Certificate & SENASICA OISA Inspection (CIS). Compliant pets are eligible for 0 days quarantine.

Direct Flights vs Connections
Airport Arrival Protocol: Upon deplaning in Mexico, proceed to the SENASICA / SAGARPA OISA module before exiting customs. The officer conducts a physical check for external parasites and stamps your clearance in 10–15 minutes.
Layover & Transit Biosecurity Rules
Domestic Mexican connections: Once your pet clears the SENASICA OISA inspection at your first port of entry (e.g. Mexico City MEX or Guadalajara GDL), you receive the green CIS certificate, which allows smooth transit on domestic flights.
Driving & Surface Transit Options
Driving Across the US-Mexico Border: At land ports (San Ysidro, Otay Mesa, El Paso, Laredo), stop at the OISA checkpoint. If entering via the Cross Border Xpress (CBX) bridge from San Diego into Tijuana Airport, an OISA station is located inside the terminal.
Climate & Temperature Embargoes
Commercial pet food rules: You may bring one unopened commercial bag of dry pet food (up to 50 lbs / 22 kg) with USDA labels in English or Spanish. Loose bags or fresh/raw meat products are strictly confiscated.
