Documents for flying with dog

What document does Segarpa want at the airport for dogs? The website states shots and such should be documented on vets letterhead if a private practice.
When traveling into Baja I had all the documentation on letterhead but was told it should be a 7001. However they would let me pass this time. What are your experiences?
Do they still require rabies shots with in a year or accept US 3 year shots.
Looking forward to our month long visit...but do not want to arrive with the wrong paperwork (according to who ever is on duty...such is Mexico

As far as I know you need a rabies certificate that is valid with shot date and expiration date. A letter from a vet certifying good health and that the dog has no worms, etc.. FWIW, they never even looked at our stack of papers when we drove across the border.

Thank you. We are flying and they are very strict when flying. We are used to dealing with Los Cabo Segarpa, wondering if Quad.wants the 7001 or letterhead certification. Always used letterhead but last time they wanted the 7001. Seems it depends who is on duty. Just wanted any heads up of potential problems.

It always depends on who ison duty, and how recently they've read the latest updates. Es Mexico.

Flying in they are always strict. Every "i"dotted, every "t" crossed. They didn't even look at either of my cats but went over the paperwork in its entirety. I read the Senasica website thoroughly first for the latest. And then I printed it out to have with me in case of problems. My vet in Canada got the proper forms for me. Driving in is a different world.

It needs to say the pets are free from internal & external parasites.

Guad airport is especially strict. MUST have the International Vet form. Must have rabies current within 1 year. Current on all other shots as well. Current on flea drops - best if the Vet says he administered them. Plus they toss the bedding so use disposable diapers.

This link may help, has the most up-to-date information from the USDA that I could find for traveling with pets to Mexico:

Looks like there are currently 2 accepted options for paper work:
Option 1: USDA form 7001 it will need to be signed off by an accredited veterinarian (check not all vets are accredited by the USDA, if your current vet is great) and a Veterinary Services veterinarian (i.e. a vet that works for the USDA). The USDA charges to stamp the 7001. It typically runs around $35 last time I checked.

Option 2: A Health Certificate signed by an accredited veterinarian. There is a form on the link I gave that the accredited vet should print on their letter head and sign etc. It should have all the appropriate language in Spanish and English.

Good luck, and I hope this helps.

Thank you mouse doc....Perfect
