Coming straight from the US, land only at Stockholm Arlanda or Gothenburg Landvetter, and you must report the dog to customs, or it can be refused or, in the worst case, put down. Go to the red channel and tell a customs officer, or declare online first and use the green lane with your number ready. Fill in form E9.204. Carry the EU health certificate stamped at your EU entry point, the chip and rabies records. No tapeworm rule for Sweden.

Your dog needs an Animal Health Certificate from an Official Vet, issued within 10 days of entering the EU. It then covers 6 months of travel in the EU and 6 months to come home. Regular practices charge £150 to £300 for it. Independent AHC vets who do nothing else charge from £69, often meeting you in a car park in the evening. Only a handful of airlines take a dog in the cabin out of the UK, and three of those refuse Gatwick. No airline brings a pet dog back into the UK in the cabin, so plan the return by LeShuttle or ferry before you book anything.

We didn’t find any of our verified pet-friendly carriers flying LHR → ARN non-stop. There are one-stop options below where both legs take a dog in the cabin.
Every airline below takes a dog in the cabin on that leg, and each leg has been checked against the same country rules as a direct flight. Two legs means two check-ins and a dog who has to cope with the change, so it’s the fallback, not the first choice. If you leave the airside area at the stop, that country’s entry rules apply to your dog too.
