If you are travelling with pets to or from Norway, you should contact the Norwegian Food Safety Authority prior to the trip in order to establish which rules apply.
It is the Norwegian Food Safety Authority that administers the veterinary regulations for live animals.
You have to enquire in the red channel upon entering Norway. The exception is if you are travelling with a dog, cat or ferret directly from Sweden. If your papers are in order, you may pass through the green channel.
Travelling with horses to and from Norway
There are separate regulations when travelling with horses to and from Norway.
Animals as household goods
When moving to Norway from abroad, you may bring your pet without paying customs duty or VAT. You have to have lived abroad for at least one year, and the pet must have been owned by you. The exemption does not apply to pets in a business undertaking that moves to Norway.
You must always contact the Norwegian Food Safety Authority to obtain the necessary permit to import the pet.
