The dog or cat must be identified by means of a microchip and must have a European passport.
All pets must be reported to Swedish Customs. An exception applies to Norwegian pets.
There are two ways to report:
Report on-site at the border by choosing the red zone ("Something to declare").
Register online in advance through the Swedish Customs website. This is only possible if you live in an EU country and your pet has a European pet passport. After online registration, you may use the green zone ("Nothing to declare"). Keep your registration number and pet passport ready for possible inspection.
The dog or cat must be vaccinated against rabies. The first vaccination must be given at least 21 days before departure, and must be repeated within the validity period. A vaccination after this period is considered a first vaccination and is only valid again after 21 days.
A puppy/kitten must be at least 12 weeks old when receiving its first rabies vaccination, which means they can only cross the border from the age of 15 weeks.
The dog or cat must not interfere with the driver and must be protected against sudden movements or in case of an accident. This can be achieved through a securely fastened car crate, a special harness attached to the seat belt, or a closed luggage compartment with a safety net or barrier.
In Sweden, dogs must be kept on a leash between March 1 and August 20 in natural areas to protect wildlife during the breeding season. National parks and most nature reserves require dogs to be leashed at all times.
When traveling with more than five animals, they must undergo a clinical examination, and their passport must include an additional certificate issued by the official veterinarian of the country of departure. The animals will then be subject to commercial transportation regulations.
The non-commercial transportation rules still apply when transporting more than five animals for participation in competitions, exhibitions, sporting events, or training, as long as the animals are older than 6 months and the owner can provide written proof of participation.
Don’t forget to check the regulations for all the countries you’ll be traveling through,
such as Norway, Denmark or Finland.
