Planning a Puerto Vallarta getaway with your furry friend? You're probably wondering about the paperwork maze ahead. The truth? Both entering Mexico and re-entering the US have their own special brand of bureaucratic ADVENTURE, but one might surprise you more than the other.
La verdad rápida / The Quick Truth: Mexico's entry process involves more upfront paperwork steps, but US re-entry now includes some curveball requirements that could catch you off guard.
Mexico Entry: More Steps, But Predictable
What You Actually Need (And What You Don't)
Here's the good news: Mexico no longer requires a health certificate from US or Canadian pets as of 2019. That's one less vet visit to stress about! However, your airline might still require one, so check with your carrier first.
Documentos necesarios / Required Documents:
- Current rabies vaccination proof
- Deworming certificate (within the last 6 months)
- Veterinary letter confirming your pet's health
- Completed online PMVF registration
- Import authorization approval
Lo que necesitas saber / What You Need to Know:
The SENASICA inspection at Puerto Vallarta airport is mandatory, but here's the pleasant surprise – they don't charge for it! Your pet will get a physical inspection where officials specifically check for ticks and worms.

The Carrier Rules That Trip People Up
Your pet must travel in a carrier with absolutely no bedding. This catches many travelers off guard, especially those planning longer stays in puerto vallarta condo rentals where comfort seems essential.
Regla importante / Important Rule: You can bring up to 2 pets per person without additional fees. After that, import fees may apply.
US Re-Entry: The New Curveball
The Screwworm Game Changer
Here's where things get interesting. As of November 22, 2024, Mexico is considered affected with screwworm, which means ALL dogs returning to the US from Mexico – including American dogs who were just vacationing – must meet APHIS screwworm freedom certification requirements.
This is relatively new and catches many travelers completely unprepared. Unlike the predictable Mexico entry process, this requirement can vary based on your veterinarian's ability to provide the proper certification.
CDC Requirements: The Double Whammy
On top of screwworm certification, the CDC has separate requirements for dogs entering the United States. Miss these, and your dog gets denied entry – no exceptions, no appeals at the airport.
El problema real / The Real Problem: Unlike Mexico's clear documentation list, US re-entry requirements are less straightforward and can change. You'll need to consult both APHIS and CDC websites directly for current specifics.

Renter-Specific Tips for Both Sides
Before You Book Your Zona Romántica Stay
If you're planning an extended stay in one of Puerto Vallarta's amazing vacation condos, start your pet paperwork at least 6 weeks early. This gives you buffer time for any complications.
Consejo de oro / Golden Tip: Many pet-friendly accommodations in Old Town and Amapas neighborhoods have relationships with local veterinarians who understand the cross-border requirements.
Documentation Storage Strategy
Keep both digital and physical copies of ALL documents. Store them in multiple locations:
- Phone photos/PDFs
- Email to yourself
- Physical copies in carry-on
- Additional physical copies in checked luggage
The Airline Variable
Different airlines have different pet policies, even when government requirements are the same. Southwest, American, and United all have slightly different interpretation of documentation requirements.
Verificación doble / Double Check: Call your airline 48 hours before departure to confirm current pet travel requirements, especially for the return journey.

Which Process Actually Causes More Stress?
Mexico Entry: Predictable but Detailed
Pros:
- Clear documentation requirements
- No inspection fees
- Predictable timeline
- Well-established process
Contras:
- Multiple steps required
- Physical airport inspection
- No bedding allowed in carriers
- Online registration can be confusing
US Re-Entry: Simpler but Unpredictable
Pros:
- Generally faster processing
- Familiar system for US residents
Contras:
- New screwworm requirements
- Requirements can change
- Higher stakes (denied entry = major problem)
- Less clear documentation guidelines

The Real Answer: Preparation Beats Everything
The process that stresses you out more depends entirely on your preparation level. Mexico entry has more steps but they're clearly defined. US re-entry has fewer steps but higher uncertainty.
Your Action Plan
6 Semanas Antes / 6 Weeks Before:

The Bottom Line for Puerto Vallarta Pet Travel
Mexico entry wins for "most paperwork," but US re-entry wins for "most likely to surprise you with new requirements." Neither process is impossible, but both require advance planning.
The key insight? Start early, prepare for both sides of your journey, and remember that thousands of pets travel between Puerto Vallarta and the US successfully every year.
El secreto / The Secret: Many experienced pet travelers say the Mexico entry process, while longer, is actually less stressful because the requirements are crystal clear. US re-entry uncertainty creates more anxiety, even though the actual process might be faster.
Ready to plan your Puerto Vallarta pet adventure? Start with the paperwork, but don't let it overshadow the MAGIC waiting for you and your furry friend on those beautiful beaches.
