Bringing a dog or a cat to Mexico is far less complicated than most people fear, and the rules changed meaningfully in 2026 — mostly in ways that made things simpler, with one important new requirement for dogs. The paperwork is manageable. The part people underestimate is what happens after arrival: finding a rental that genuinely allows pets, and adjusting to a climate that is harder on animals than the one they came from.
What Mexico Actually Requires in 2026
Entry for dogs and cats is handled by SENASICA, the federal agricultural health authority, at the OISA inspection office in the port of entry. Two things are worth knowing before you book a flight:
- A general health certificate is no longer required for dogs or cats arriving from the United States. This surprises people who prepared for it based on older guides.
- Dogs arriving from the U.S. do need a New World Screwworm (NWS) inspection certificate, effective August 3, 2026. It must be issued and signed by a USDA-accredited veterinarian within five days before arrival in Mexico, certifying the dog is free of screwworm, external parasites, and open or healing wounds. Cats are exempt from this one.
- Both dogs and cats still need a Certificado Zoosanitario para Importación (CZI), which you do not apply for in advance — you request it from SENASICA staff at the point of entry, where they review documents and physically inspect the animal.
The physical inspection is real, not a rubber stamp. Officials check that the animal looks healthy, has no ectoparasites, and has no fresh or healing wounds. A dog with an untreated hot spot or a recent surgical site can create a problem at the counter. Rules also differ by country of origin — arriving from somewhere other than the U.S. or Canada can change the requirements entirely, so verify against your specific departure country rather than a general guide.
Airlines are the other half of the equation, and their rules are stricter and less negotiable than the government’s. Cargo temperature embargoes are common in summer, breed restrictions apply to snub-nosed dogs on most carriers, and in-cabin space is limited per flight. Book the pet space at the same time you book your own seat, not after.
Veterinary Care Once You’re Here
This is usually the pleasant surprise. Puerto Vallarta has a solid network of veterinarians, several with English-speaking staff, and routine care — vaccinations, checkups, dental work, spay and neuter — generally costs a fraction of what owners paid in the U.S. or Canada. There are emergency clinics in the city, though 24-hour coverage is thinner than in a large North American metro, so it is worth identifying your emergency option before you need it rather than during a crisis at 2 a.m.
What does change is the health picture. The tropical climate means ticks, fleas, and heartworm are year-round concerns rather than seasonal ones, and year-round prevention is standard advice here rather than optional. Bring your pet’s records, but expect your vet to adjust the protocol to local conditions.
The heat itself deserves respect. Pavement and beach sand get hot enough to burn paw pads by mid-morning in summer, and dogs that came from a cold climate take a full season to acclimate. Walks move to early morning and after sunset, which is exactly what local owners already do.
Finding a Rental That Actually Takes Pets
This is the real constraint, and it is worth solving before you arrive. Vacation rental platforms show plenty of pet-friendly listings, but long-term rentals are a different market with different rules, and “pet friendly” often comes with limits that only surface at signing:
- Weight and count caps are common in condos — a limit of one or two small animals is typical, and large dogs narrow your options considerably.
- The HOA rules, not just the owner. An owner can say yes and the condominium regulations can still say no. Ask to see the building’s rules, not just the owner’s opinion.
- Expect an additional deposit, and clarify in writing whether it is refundable and what it covers.
- Ground-floor units and houses with outdoor space in neighborhoods like Versalles, Fluvial, and parts of the Romantic Zone tend to be more workable than high-rise condos for larger dogs.
Owners are far more flexible with a tenant they have met, so the pet is one more reason to rent in person rather than sight unseen from abroad.
Where to Go From Here
