Last spring, I made what felt like an impossible decision: I was moving to Portugal for six months, and there was no way I was leaving my golden retriever, Bailey, behind. The thought of international pet travel seemed overwhelming—until I actually did it. Now, after successfully navigating pet-friendly flights, accommodations, and border crossings across Europe and back to the States, I can tell you it’s completely doable. Here’s everything you need to know about traveling internationally with your pet in 2026.
Understanding Pet Import Requirements by Country
This is where most people get tripped up, and honestly, it’s the most critical part. Every country has different rules, and they’re not kidding around. For our move to Portugal, Bailey needed an ISO-compatible microchip (which he already had, thankfully), a rabies vaccination at least 21 days before travel, and an endorsed health certificate from a USDA-accredited veterinarian.
The health certificate alone cost me $250, and it had to be issued within 10 days of travel. Then I had to get it endorsed by the USDA, which added another $150 and required an in-person appointment in my state capital—a three-hour drive each way. EU countries have become stricter in 2026 about tapeworm treatments for dogs, too. Bailey needed a praziquantel treatment administered by our vet between 24 and 120 hours before entry, documented on the health certificate ($85).
My advice? Start this process at least 60 days before your departure date. I used PetTravel.com to verify Portugal’s requirements, but I also called the Portuguese embassy directly. Government websites can be outdated, and one missed requirement could mean your pet gets quarantined—or worse, sent back home without you.
Booking Pet-Friendly Flights and Accommodations
Here’s where the costs really add up. Most airlines charge between $200 and $500 each way for in-cabin pets (under 20 pounds in a carrier), and $300 to $800 for cargo hold transport for larger dogs. I flew Lufthansa from Boston to Lisbon via Frankfurt, and Bailey’s cargo fee was $650 one way. Yes, it hurt, but Lufthansa has an excellent pet safety record and climate-controlled cargo areas specifically designed for animals.
When booking, call the airline directly instead of booking online. Each flight has a limited number of pet slots, and they’re first-come, first-served. I learned this the hard way when my original flight sold out of pet spaces even though human seats were available. Also, avoid connecting flights if possible—every transfer is another chance for something to go wrong with your pet’s handling.
For accommodations, Booking.com has significantly improved its pet-friendly filters in 2026. I found our Lisbon apartment by selecting “Pets allowed” and reading reviews specifically mentioning dogs. The property charged a one-time pet fee of €75 (about $82), which is pretty standard now. Pro tip: message hosts directly before booking to confirm size restrictions and any additional pet fees not listed.
Managing Costs: What You’ll Actually Spend
Let me break down what I spent for Bailey’s international journey, so you can budget accordingly:
- Vet visit and health certificate: $250
- USDA endorsement: $150
- Tapeworm treatment: $85
- IATA-approved travel crate: $180
- Flight fee (one way): $650
- Pet insurance through SafetyWing: $45/month
- Accommodation pet fees: $82
- Miscellaneous supplies (travel bowls, calming aids, etc.): $75
Total for one-way international travel: approximately $1,472, not including the return trip.
One cost-saver I discovered: SafetyWing now offers pet insurance that covers veterinary emergencies abroad. For $45 monthly, I had peace of mind knowing Bailey was covered for up to $10,000 in emergency vet care while we were in Portugal. We didn’t need it, thankfully, but when a friend’s dog ate something questionable in Barcelona, their coverage saved them over $2,000 in emergency vet bills.
Day-of-Travel Tips That Actually Matter
The night before our flight, I barely slept. But I’d done everything right: I’d exercised Bailey thoroughly that day, fed him a light meal four hours before departure (per airline requirements), and packed his favorite blanket in his crate. Here’s what else made the difference:
Arrive at the airport a full three hours early for international flights with pets. You’ll need extra time for airline staff to inspect your pet’s paperwork and crate. Bailey’s crate had to meet specific IATA requirements: sturdy enough to contain him, proper ventilation on all sides, and “Live Animal” labels on the exterior. The airline provided the labels, but I’d already attached a pouch with spare copies of all his documents to the crate door.
I skipped sedatives despite my vet offering them. Most airlines actually prohibit sedated pets in cargo due to breathing risks at altitude. Instead, I used calming pheromone spray in Bailey’s crate ($22 from Chewy) and included a worn t-shirt that smelled like me.
The hardest part? Watching them take Bailey away at baggage drop. But when I picked him up in Lisbon, he was totally fine—tail wagging, ready to explore his new city.
Navigating Ground Transportation and Local Activities
Once you’ve arrived, the adventure continues. I rented a car through Discover Cars for our Portugal road trips, and their filter for “pet-friendly vehicles” made it easy. The rental company charged an additional €50 cleaning fee (about $55), which was disclosed upfront. Most European trains and buses allow pets, though sometimes with size restrictions or muzzle requirements.
For activities, Viator has added pet-friendly tour filters in 2026, which is brilliant. I booked a dog-friendly Sintra day trip through them ($95 per person, dog free), and Bailey got to explore castles and gardens with us. Check local regulations, though—some historic sites and beaches have seasonal pet restrictions.
Bottom Line
Traveling internationally with a pet in 2026 requires planning, patience, and a decent budget—figure on $1,500 to $2,500 for international travel depending on your pet’s size and destination. Start preparing at least two months before departure, budget for unexpected vet visits, and use booking platforms like Booking.com and Discover Cars with pet-friendly filters to simplify your search. The paperwork feels bureaucratic and the costs add up, but watching Bailey run on a Portuguese beach made every penny and every form worth it. Your furry friend can absolutely join your international adventures—you just need to plan ahead and stay organized. Safe travels!
