With a dog to the USA: documents, weight limits and airline choice
Moving a dog to the USA is harder than it seems. Trains and taxis accept pets almost everywhere, but airlines and border control have stricter rules.
Two bottlenecks decide everything: the dog's weight including the carrier and the breed. These determine whether your pet flies in the cabin or stays home.
If your dog exceeds the cabin weight limit, you'll need to find a carrier with a higher weight allowance or prepare the dog for the cargo hold. Below, in order: documents, weight, brachycephalic breeds, airport checks, and countries with bans.
Documents: what your dog needs for the USA
💡 In short:
- Your dog needs a microchip, a rabies vaccination, and a veterinary certificate before departure.
- For the USA, add the online CDC Dog Import Form for each dog.
- Dog import to the USA: 09/2026, verified on the official CDC website
Documents fall into two sets: one for travel within Europe and a separate one for entering the USA. Within Europe, your dog needs an international passport, a microchip, and a valid rabies vaccination. Revaccination and parasite treatment timelines vary by country, so check the schedule with your veterinarian in advance.
For the USA, add the form. The CDC requires you to fill out an online form for each dog: print the receipt or keep it on your phone, as it will be asked for both at boarding and at the border. The receipt is valid for six months from the date of issue and covers one dog (as of 09/2026, CDC). Puppies under six months are not allowed into the country.
If your dog has been in a high-risk rabies country in the past six months, there are more requirements. You need an additional form about the vaccination and microchip, and entry is allowed only through an airport with a registered animal care facility and a reservation made in advance (as of 09/2026, CDC on high-risk countries).
Weight and breed: where most pets get rejected
The weight limit is calculated together with the carrier, and this is where most animals are turned away. airBaltic allows pets in the cabin up to 8 kg including the bag, with carrier dimensions not exceeding 55 x 40 x 23 cm (as of 09/2026, airBaltic rules). An adult French bulldog in a hard carrier almost always exceeds this threshold.
The second restriction is breed. Brachycephalic breeds (French and English bulldogs, pugs, boxers) handle flights worse than others. Because of their flat faces, they have more difficulty breathing during pressure changes, and under stress this is dangerous for the heart. That's why some airlines don't take them on board at all, while others allow cabin transport only and only on short flights.
How to choose an airline
Compare carriers before buying your ticket. Once you've paid, it's too late to switch airlines, and the pet spot is booked separately from your seat.
Airline | In cabin | In cargo hold | Price per carrier |
|---|---|---|---|
airBaltic | up to 8 kg with carrier, bag up to 55 x 40 x 23 cm | yes, for larger pets | 70 € per one-way flight (as of 09/2026, airBaltic fares) |
La Compagnie | up to 8 kg with carrier | no | check the La Compagnie website |
Check three things before you pay for the ticket. First: whether the dog's weight with the carrier passes. Second: whether your breed is accepted. Third: how many carriers the airline takes per flight, because spots are limited and booked in advance.
On board airBaltic, the dog travels in a closed carrier under the seat and stays there for the entire flight (as of 09/2026, airBaltic page). La Compagnie transports small animals only in the cabin and does not accept them as checked baggage (as of 09/2026, La Compagnie rules).
Train, car, and carrier
Over land, everything is noticeably simpler. In a car, transport your dog in a hard carrier or a soft bag secured with a seatbelt. On your lap or in the front seat, the pet distracts the driver and is unprotected during sudden braking.
On trains, small dogs travel according to the carrier's rules: some require a separate ticket, some don't. Bring a mat, place it on the floor or on the adjacent seat, and train your pet to lie calmly.
Heat and cold: when to leave your dog at home
Weather changes the entire day's plan. In extreme heat and freezing cold, it's better not to take your dog on the road: asphalt and air exhaust the pet faster than you'd think. In the southern USA during heat waves, long walks are off the table, the animal simply can't breathe.
Feeding schedules also dictate your itinerary. If your dog eats three times a day, find in advance where to get fresh water and food, and adjust your excursions around that. A hungry pet in an unfamiliar city gets more anxious, and you lose half a day searching.
Get your dog used to travel from an early age
A dog is prepared for travel in advance, not on the day of departure. Start with short car rides, then try the train, and only then move on to flying. This way the pet gradually gets used to noise, shaking, and unfamiliar smells.
Separately, get your dog used to loud sounds: airports, train stations, and airplane cabins sound unusual. With a puppy, it's worth working with a dog trainer, especially if a long flight is ahead. A calm dog in a carrier saves you nerves and time at checkpoints.
What actually happens at the border and at the airport
Scary videos about inspections are exaggerated. In practice, everything depends on the route and the shift. At the US border, you'll be asked for the CDC receipt, and they may check the microchip.
Always keep original documents at hand: a check can happen at any moment.
Where dogs are not allowed
There are countries and regions with a complete ban or strict restrictions.
Before buying a ticket, check the destination country's rules on the official website: you'll find the current list there. Bans change, and changing a ticket after the fact is expensive. If a destination is closed to brachycephalic breeds, choose another place. It's useful to look at a selection of dog-friendly countries in advance.
⁉️🤔 Frequently asked questions
Does a dog need a separate form to enter the USA?
Yes, the CDC requires a separate form for each dog. Fill it out online, receive the receipt by email, and keep it on your phone or on paper. The receipt is valid for six months from the date of issue and works for entry from one country.
How much does flying with a dog in the cabin cost?
The price depends on the carrier and the route. With airBaltic, a cabin carrier costs 70 € per one-way flight (as of 09/2026, airBaltic.com), and on connecting flights you pay for each segment separately. Check the exact amount when booking the pet spot.
Can a French bulldog fly in the cabin?
Yes, but not always. A French bulldog with a carrier often exceeds the 8 kg limit, and brachycephalic breeds are banned from the cargo hold. The only option is to find a carrier with a suitable weight limit. Check the specific airline's rules in advance.
What if the dog weighs more than 8 kg?
There are two options: the cargo hold or cargo shipping. For brachycephalic breeds, the cargo hold is dangerous, so only the cabin works for them.
In short: what to book
First the pet spot, then everything else. Airlines take a limited number of carriers per flight, and available spots sell out faster than tickets.
If your dog is up to 8 kg with the carrier: choose the cabin.
If over 8 kg: choose the cargo hold or cargo shipping.
Book the pet spot right after buying your ticket, and get the documents done a couple of weeks before departure.
