The short version: this is the easy direction.

Driving down to Puerto Peñasco with your pet? Here's what Mexico actually requires — and it's less than most people think.

No health certificate needed

Since December 16, 2019, Mexico no longer requires a health certificate to bring a dog or cat into the country. You can head to the border without a folder of vet paperwork.

What happens at the border

Mexico's animal-health agency, SENASICA, may inspect your pet on arrival at their inspection office (OISA). They're simply confirming your pet:

  • Shows no signs of infectious or contagious disease,
  • Is free of external parasites (fleas, ticks, fly larvae), and
  • Has no fresh or healing wounds.

Make the inspection painless

  • Clean carrier or a leash. If the carrier is dirty or packed with bedding, toys, or food, they can make you empty and disinfect it.
  • Pet food — up to one sealed 50-lb bag per family. It must be dry, in the original factory-sealed bag, and chicken- or fish-based (no beef, pork, goat, or sheep). Loose or opened food is limited to about a day's ration. There's no fine for pet food, but anything off-spec gets confiscated at the crossing — so keep it sealed and check the label.
  • Treat for fleas and ticks before you leave. If they spot ticks, SENASICA can take a sample and hold your pet until it's cleared. Uncommon, but easy to avoid.

About the rabies shot

Mexico doesn't require you to present rabies paperwork at the border under the current rule. Still, keep your pet's rabies vaccine current and carry the certificate — it's smart practice and you'll want it for the trip home.

Cross often?

Ask about Mexico's "Pet Program – Frequent Traveler" registration. If you're a regular between the U.S. and Rocky Point, it can smooth out repeat crossings.

Heads-up: Coming home is the direction with the newer, stricter rules — especially for dogs (CDC form, microchip, and a screwworm certificate). Read the companion guide, Bringing Your Pet Back Into the U.S., before you make the return trip.

I'm a Realtor, not a vet or customs officer. Border rules change — confirm current requirements with SENASICA/USDA APHIS and your veterinarian before you travel.
