Pet Travel Requirements: Mexico to United States
Statutory requirements for bringing dogs and cats from Mexico into the United States under CDC 2024–2026 biosecurity regulations. Because Mexico is categorized as a high-risk rabies country for dogs, all dogs mandate ISO 11784/11785 microchips, valid CDC Rabies Vaccination forms, minimum 6 months age, online CDC Dog Import Form receipts, and clearance at CDC-approved entry ports.
Can I travel with my pet from Mexico to United States? Yes. Companion dogs and cats can enter United States from Mexico under non-commercial regulations established by US Centers for Disease Control and Prevention (CDC) & USDA APHIS (CDC Dog Importation Regulations (42 CFR Part 71) & USDA Animal Welfare Act). Entry requires an ISO 11784/11785 microchip, rabies vaccination with a 1–3 months waiting period, recommended / conditional for unvaccinated, and an endorsed CDC Rabies & Microchip Record or USDA Endorsed Export Form. Compliant pets are eligible for 0–28 days (depends on vaccination origin & titer).
Key Route Factors at a Glance
Recommended / Conditional for Unvaccinated
Rabies titer test (FAVN) is required if vaccinated in Mexico and seeking direct release without CDC animal care facility quarantine.
0–28 Days (Depends on Vaccination Origin & Titer)
Dogs vaccinated in the US with USDA endorsement have 0 days quarantine. Dogs vaccinated in Mexico without titer require reservation at a CDC-registered Animal Care Facility for 28-day quarantine.
