Quick answer: Yes, you can bring a dog or cat on vacation to Cozumel. Mexico doesn't quarantine healthy pets, and cats arriving from the U.S. or Canada need no health certificate. Dogs coming from the United States do need one new document: since August 3, 2026, Mexico requires a New World screwworm inspection certificate signed by a USDA-accredited vet within 5 days of arrival. Every pet gets a quick SENASICA inspection at the airport. The ferry from Playa del Carmen takes leashed pets, and many vacation rentals do too, but most resorts and beach clubs don't. Plan for the heat, and for getting home: dogs going back to the U.S. need a microchip, a CDC Dog Import Form and a screwworm certificate from a vet in Mexico. Rules have changed several times since 2024, so check the official sources linked below before you book.
Cozumel is a relaxed, small-town island where dogs are part of everyday life, and plenty of visitors come with theirs. Here's how to do it smoothly.
What Do You Need to Bring a Dog or Cat to Mexico?
The rules depend on the animal and on where it's coming from. For a pet traveling as a tourist from the U.S. or Canada, this is what applies in late 2026:
| Requirement | Dogs from the U.S. | Dogs from Canada | Cats from the U.S. or Canada |
|---|---|---|---|
| Health certificate for Mexico | Not required | Not required | Not required |
| Screwworm inspection certificate | Required since Aug 3, 2026: signed by a USDA-accredited vet within 5 days of arrival | Not required if the dog hasn't been staying in the U.S. | Not required |
| SENASICA inspection on arrival | Yes | Yes | Yes |
| Rabies and parasite records | Bring them: inspectors may ask | Bring them | Bring them |
| Quarantine | No, if healthy | No, if healthy | No, if healthy |
The screwworm rule exists because of outbreaks of New World screwworm, a parasitic fly whose larvae infest wounds, in Mexico and more recently in the United States. The American Veterinary Medical Association has a summary of the new certificate. Pets from other countries have different rules, so check with the nearest Mexican consulate.
Always confirm before you go. Pet rules between the U.S. and Mexico have changed several times since 2024. Check SENASICA (Mexico's agriculture health agency), the USDA APHIS pet travel pages and your airline a few weeks before your trip and again a few days before.
What Happens at the Airport When You Arrive With a Pet?
After immigration and baggage claim, take your pet to the SENASICA (OISA) inspection desk before customs. An inspector looks your dog or cat over for illness, ticks, fleas and wounds, and checks your paperwork. If everything is in order it takes a few minutes. If the inspector finds ticks or a wound, your pet may need treatment by a vet or a short hold before it's released, so make sure it's been treated for parasites before you fly.
- Travel with one or two pets to keep it simple. Larger numbers can trigger extra import paperwork and fees.
- Bring only a little food, sealed and enough for the journey. Inspectors can confiscate food, and you can buy good pet food on the island.
- Bring a clean crate and bedding. Dirty bedding can be taken away.
Can You Fly Into Cozumel With a Dog?
Yes. Several airlines fly nonstop into Cozumel International Airport (CZM) from the U.S. and Canada (see our airlines guide), and most allow small dogs and cats in the cabin in a carrier that fits under the seat. Larger dogs have to fly as checked baggage or cargo, and many airlines stop accepting pets in the hold during the hot months or ban snub-nosed breeds like bulldogs and pugs. Each airline has its own fees, carrier sizes and limits per flight, so book your pet's spot when you book your seat.
If you can't get a pet-friendly flight to Cozumel, fly into Cancún and come over on the ferry instead.
Can You Take a Pet on the Cozumel Ferry?
Yes. Ultramar, the main ferry company between Playa del Carmen and Cozumel, says pets ride at no extra charge in designated areas of the boat, on a leash and with their owner. Some travelers report being asked to use a carrier for small pets or a muzzle for large dogs, so bring both, tell the ticket office you have a pet, and ask about the current rules. Winjet and Xcaret Xailing set their own pet policies, so ask before you buy a ticket. The crossing takes about 45 minutes. Our ferry guide has schedules and fares.
Where Can You Stay in Cozumel With a Pet?
- Vacation rentals are your best bet. Many homes and condos accept pets, sometimes with a deposit or cleaning fee. Always ask before you book, and mention the size and number of pets.
- Small hotels: a few downtown hotels and guesthouses accept small dogs. Ask directly.
- Big resorts and all-inclusives generally don't accept pets, apart from service animals.
Our where to stay guide compares areas, and you can browse places in our lodging directory.
Are Cozumel Beaches Dog-Friendly?
Partly. Beach clubs and hotel beaches usually don't allow dogs, but you'll see local dogs on quieter public beaches early in the morning and late in the afternoon. Keep your dog on a leash near other people and pick up after it. From about May to October, sea turtles nest on Cozumel's beaches, mostly on the east side and in the south. Nests are protected, so keep dogs off the nesting beaches in those months: a dog can dig up a nest or chase hatchlings. Our free beaches guide lists the public beaches.
Downtown, the malecón (waterfront promenade) is a popular place for an evening dog walk when it cools down. Some cafés and restaurants with outdoor seating welcome well-behaved dogs. Ask before you sit down.
How Do You Keep Your Pet Safe in Cozumel's Heat?
| Risk | What to do |
|---|---|
| Heat and humidity | Walk early morning and after sunset. Carry water. Never leave a pet in a parked car, even for a few minutes. |
| Hot pavement and sand | If it's too hot for the back of your hand, it's too hot for paws. Stick to grass and shade at midday. |
| Ticks, fleas and mosquitoes | Use a vet-approved tick and flea preventive before and during the trip. Ask your vet about heartworm prevention, since mosquitoes are around all year. |
| Toads | Large cane toads come out at night after rain and are poisonous to dogs that bite or lick them. Keep your dog close at night and rinse its mouth and see a vet right away if it mouths one. |
| Sea and currents | Strong currents run off the east coast. Let dogs swim only in calm water on the west side. |
| Street dogs | Most are friendly, but keep your dog on a leash and avoid letting it greet dogs you don't know. |
Are There Vets in Cozumel?
Yes. San Miguel has several veterinary clinics and pet stores that sell food, preventives and supplies, and some vets speak English. Ask your host or the Humane Society for a recommendation before you need one, and keep your pet's records on your phone. Save the clinic's number in case of an emergency at night or on a Sunday.
How Do You Get Your Dog Back Into the United States?
Plan this part before you leave home, because some of it has to happen on the island. For a dog that has only been in the U.S. and Mexico (which the CDC classes as low risk for dog rabies), you need:
- A microchip readable by a universal scanner (ISO-compatible).
- Age at least 6 months on arrival in the U.S.
- A CDC Dog Import Form receipt, filled out online before you fly back. It's free. See the CDC's dog import page.
- A screwworm freedom certificate from an authorized veterinarian in Mexico, from an inspection no more than 5 days before you travel. Book a vet appointment in Cozumel for the end of your stay. See APHIS for the details.
Cats don't need CDC paperwork to enter the U.S., though some states and airlines have their own rules. Canada and other countries have different requirements, so check with your own government before you travel.
Can You Adopt a Dog or Cat in Cozumel?
Yes, and many visitors do. Cozumel has a lot of street dogs and cats, and the Humane Society of Cozumel Island has been rescuing, sterilizing and rehoming them since 1995. You can visit the shelter, walk dogs as a volunteer during your trip, sponsor an animal, donate, or adopt and take your new pet home. The shelter helps with the vet certificate and paperwork. Read how to donate, volunteer or adopt at the Humane Society of Cozumel.
