Hey everyone! Quick heads-up if you’re planning on crossing the border into Mexico with your dog anytime soon 🐾
Both the U.S. and Mexico have put strict new travel rules in place to stop the spread of New World Screwworm. If you're traveling back and forth, here’s what you need to know so you don't get stuck at the border:
Going to Mexico: Your dog needs a New World Screwworm Inspection Certificate signed by a USDA-accredited vet. They’ll also check that your dog has no open or healing wounds, is clean, and is free of fleas or ticks.
Coming back to the U.S.: You’ll need a Screwworm Freedom Certificate issued in Mexico by an authorized clinical veterinarian (MVRA).
The 5-Day Window: both of these certificates are only valid for 5 days from the time of the exam. You can't get them weeks in advance.
Standard CDC rules still apply: Don't forget your usual CDC Rabies paperwork for coming back into the country!
(Note: Cats are currently exempt from the screwworm certificate requirement, though border officials will still do a standard visual check).
Because of that tight 5-day window, you'll want to map out your vet appointments on both sides of the border before you hit the road.
For all the official details, the step-by-step checklist, and the most up to date information, check out the USDA Pet Travel Page before you go!
If you've got an upcoming trip planned, give us a call at the clinic and we'll help get your dog squared away for travel!
