Traveling With a Dog as a Digital Nomad: A First-Timer’s Guide
Three weeks of research before I bought the ticket.
Airline pet policies, carrier size requirements, health certificates, Lisbon's entry documentation for dogs. I had a folder with fourteen open tabs. I read the same Reddit thread four times.
I bought the ticket anyway.

The Part That Takes the Longest: Paperwork & Documentation
This part has no shortcut. Health certificate from a licensed vet, dated within ten days of departure. Rabies vaccination record. EU entry requirements if you're flying into Portugal — microchip, specific vaccine timing, the right form signed by the right person.
Call the consulate. Call the vet. Start earlier than you think you need to.
Once the paperwork is done, everything else is just logistics.
Choosing the Right In-Cabin Carrier
The carrier is the decision everything else depends on.
Most major airlines publish size limits for in-cabin pet carriers. In practice, soft-sided bags have more flexibility than the numbers suggest — a centimeter or two over rarely gets flagged, especially on full-service carriers where the priority is whether the bag physically fits under the seat. What matters is that it's soft, that it compresses, and that your dog has enough room to shift position without pressing against the sides.
I use this one. It covers the routes I fly most — transatlantic, Asian carriers, US domestic. Mochi fits. It fits. That's the criteria.

The mesh panels matter too. A ten-hour flight in a poorly ventilated carrier is not something either of you wants to find out about mid-air.
Airport Logistics: Security, Waiting Gates, and Harnesses
Mochi knew something was happening before I'd finished packing.
He was running between rooms, trying to get into the suitcase, pushing his nose into every bag I zipped. New situation, full energy.
The harness went on before we left the apartment. He's been an excitable dog since the day I got him. The harness and bungee leash mean I can actually hold onto him when he decides the man with the rolling suitcase across the terminal is the most interesting thing he's ever seen. At JFK, that happened twice before we reached security.

Without the harness, one of those times ends differently.
The Long-Haul Flight: What to Expect Onboard
Security is straightforward if you've done it once. Carrier goes through the scanner. Mochi comes out with me, back in on the other side.

The harder part is the wait.
We had ninety minutes at the gate. He was still wired. I found a seat near a pillar away from the main foot traffic, unclipped the collapsible bowl from the outside of the bag, filled it from the water bottle, and put it on the floor. He drank.

Airports are loud and strange-smelling and full of movement. Something to drink, something familiar in front of him — that's what the ninety minutes needed.
At the gate, a crew member checked the carrier. Soft sides, easy to assess. We were waved through.
The flight itself
Mochi went under the seat in front of me before we'd pushed back from the gate.
I'd put his toy in with him — a small stuffed thing he's had for three years, well-worn, always packed. I heard him settle around it somewhere over the Atlantic. After that, nothing. No noise, no movement, no indication that there was a dog under seat 24C.
The passenger next to me noticed the carrier during boarding and said nothing. By cruising altitude he'd forgotten about it.
Landing in a New City: Customs and First Walks
Customs in Lisbon took forty minutes. Mochi waited in the carrier, toy still in there with him.
Outside the terminal, I found a strip of grass near the taxi rank. Clipped the leash, opened the carrier. He walked out, stretched, and immediately started investigating the ground with the focused intensity of a dog who has been sitting still for eleven hours.
The poop bag dispenser was already clipped to the harness strap. First walk in a new country, new smells, new everything — I wasn't going to be the person digging through a bag for a plastic bag on a Lisbon sidewalk at 7am.

He found a spot. We handled it. We moved on.
The city didn't know we'd just landed. Mochi didn't care. He was already onto the next thing.
