One dog, two countries, several modes of transportation, and a whole lot of paperwork. Here’s how we traveled from Caye Caulker to Mérida, Mexico with Tito – and what you need to know if you’re planning an extended stay in Mexico with your four-legged travel companion.
If you think traveling from a tiny Caribbean island to a bustling Mexican city is a big adventure, try doing it when you’re a dog who has never left the island, never seen a car, and whose only experience with boats involves the short ferry ride across the Split.
Meet Tito
Until recently, his world consisted of Caye Caulker, familiar faces, sandy streets, and the occasional boat ride across the channel. Then came our trip to Mexico, where we’ll be spending an extended period. And while my husband and I had plenty to think about, Tito had absolutely no idea what was coming.
6:45 AM: The "Great Escape” from Caye Caulker
Our day started early. At 6:45 AM, we loaded Tito and our luggage onto a golf cart and headed to the San Pedro Belize Express water taxi terminal. Our boat was scheduled to leave at 7:30 AM for Belize City.
The first challenge? Getting Tito into his travel crate.
Let’s just say he wasn’t impressed. Being confined in a crate is definitely not his favorite activity, and he made sure we knew it.
A tip for fellow dog owners: I’ve heard from a reliable source that Caribbean Sprinter allows dogs to travel without a crate. If your dog isn’t a fan of being confined, it may be worth checking with them before booking.
Once we were on the water taxi, the journey was officially underway. For Tito, this was already a major upgrade in adventure level. For us, it was just the beginning of a very long day.
From Belize City to the Mexican Border
We had arranged a shuttle service from Belize City to Mérida. Unfortunately, things got off to a rocky start. The company changed the conditions of our trip along the way, which made the beginning of our journey less than ideal.
However, there was one very positive surprise: both drivers were wonderful with Tito.
The driver from Belize City to the Mexican border and the driver who took us from the border to Mérida were both genuine dog lovers. Having people who were comfortable around Tito made a huge difference, especially during such a long and unfamiliar journey.
After all, imagine being a dog who has never seen a car suddenly spending hours in one!
Crossing the Border: Tito's First Immigration Experience
At the Belize border, we went through immigration. The good news? Belize immigration does not require any documents for Tito to leave the country.
Since Tito is a bit of a big baby and we didn’t want to leave him alone in the van while we walked through the building, we decided to take him with us.
We met our Belize driver in the parking lot after immigration. This turned out to be a great opportunity for Tito to stretch his long legs, explore a little, and take a few laps around the parking lot before we continued.
Next came Mexican immigration.
My husband and I took turns going through immigration so that one of us could stay with Tito. Fortunately, there were plenty of grassy areas between the buildings and around the parking lot. Tito had enough space to walk around and stay entertained while we took care of the formalities.
Once we had both cleared immigration, it was time for the most important part of the day: getting Tito officially into Mexico.
SENASICA: The Official "Dog Immigration Office"
Mexico has its own agricultural and animal health authority, SENASICA (Servicio Nacional de Sanidad, Inocuidad y Calidad Agroalimentaria). This is where you need to go when bringing your dog into Mexico.
I had done my homework before the trip and arrived with two important documents:
- Tito’s health certificate, issued by the Caye Caulker Humane Society.
- The completed SENASICA import application form, which I had downloaded from the Mexican government’s website.
There were two officers at the SENASICA office. I handed over the paperwork, expecting a straightforward process.
Instead, the officers were amused by my completed application form. Apparently, I was the first person they had encountered who had actually brought the form with them already filled out!
They didn’t require a separate rabies vaccination certificate. However, they did ask for something resembling a vaccination record or vaccination ID, listing all the vaccines Tito had received.
Luckily, I speak Spanish, which helped me navigate the conversation. After some discussion (mostly about Mexican music and tequila), the officers agreed to inspect Tito instead of insisting on the additional vaccination document.
And, of course, Tito passed his inspection with flying colors. He looked healthy, received a few well-deserved pets from the officers, and was cleared to enter Mexico.
We were issued an official receipt confirming his entry.
Tito was officially an international dog!
With the doggy immigration process complete, we collected our luggage and passed through the new X-ray machine at Mexican customs. Then, finally, we were on our way.
So, what Documents Do You Need to Bring a Dog from Belize to Mexico?
Based on our experience and the requirements published by SENASICA, here’s what you should prepare before traveling.
Keep in mind that our experience at the border may not reflect every inspection. Requirements and the documents requested by officials can vary, so it’s worth preparing everything in advance.
1. Certificate of Good Health (Certificado de Buena Salud)
Your dog needs an official health certificate issued no more than 15 days before entering Mexico. The Caye Caulker Humane Society recommend issuing it within a week of traveling.
The certificate must:
- Be issued by an official veterinarian or a private veterinarian on official letterhead, with their professional license number or a copy of their professional credentials.
- Include the name and address of the exporter (in the country of origin) and the importer (your destination address in Mexico).
- State the date of the rabies vaccination and its validity. Dogs under three months of age are exempt from this requirement.
- Confirm that the dog was clinically healthy during the examination before travel.
- Confirm that the dog received internal and external parasite treatment within the previous six months and is free of external parasites.
We obtained Tito’s certificate from the Caye Caulker Humane Society approximately a week before our trip.
My advice: Don’t leave this until the last minute. Make sure the certificate contains all the required information, particularly the rabies vaccination details and parasite treatment.
2. Vaccination Record (Cartilla de Vacunación)
Although the SENASICA officers didn’t ultimately insist on seeing Tito’s vaccination record, they did ask for it.
This is a document that lists all the vaccinations your dog has received, including rabies.
I recommend bringing the original vaccination record, if available, rather than relying on a separate rabies certificate alone.
3. SENASICA Import Application Form (FF-SENASICA-003)
This is the application form for bringing regulated agricultural, livestock, aquaculture, and fishing products into Mexico. For dogs, you’ll need the form designated FF-SENASICA-003 Perro.
You have two options:
- Complete the form at the SENASICA office when you arrive.
- Download and complete it before your trip.
I chose the second option, which meant one less thing to worry about at the border.
You can find the form on the official Mexican government website:
Even though the officers were surprised that I had completed it in advance, I was glad I had it ready.
4. Physical Inspection at the Border
Once you arrive at your Mexican port of entry, you must contact SENASICA personnel.
They will review your documents and might physically inspect your dog.
In our case, the inspection was very straightforward. The officers looked at Tito, gave him a few pets, and were satisfied that he was healthy.
After the inspection, we received the receipt confirming his authorization to enter Mexico.
Important: Don’t assume that every inspection will be as relaxed as ours. Bring all the required documents and be prepared for the officers to request additional information.
The Final Leg: Six Hours to Mérida
With all the immigration formalities behind us, we were finally ready for the last leg of our journey.
From the border, it was approximately six hours to Mérida, including a 30-minute stop along the way.
By this point, we were all pretty exhausted. Tito, however, had handled the entire adventure remarkably well, considering that he had never experienced anything like it before.
No doubt the friendly drivers helped make the long journey a little easier for him.
Eventually, we arrived in Mérida, ready to enjoy our extended stay.
One Week Later: Tito's New Routine in Mérida
We’ve now been in Mérida for a week, and Tito is beginning to feel right at home.
He has a big yard to explore, although the swimming pool remains a mystery he has yet to investigate. So far, not a single paw has gone into the water.
Luckily, La Plancha Park is just around the corner. Tito now gets to enjoy his daily morning walks and visits to the dog park.
And he’s already discovered another important part of his new routine: his favorite bar.
It’s one of the many dog-friendly places where the dogs get served first, and the waiters always have a treat ready for him.
Clearly, Tito is adapting to city life just fine.
From the sandy streets of Caye Caulker to the parks, restaurants, and big-city life of Mérida, our little island dog is discovering a whole new world.
And while the journey was long, the paperwork was a little confusing, and the crate was definitely not his favorite part, we made it.
If you’re planning to bring your dog from Belize to Mexico for an extended stay, our biggest piece of advice is simple: prepare your paperwork in advance, allow plenty of time for the border crossing, and bring lots of patience.
Your dog might not know what’s happening, but with a little preparation, you can make the journey a whole lot easier for everyone.
And who knows? Your dog might even find a favorite bar at the other end.
