The Norwegian Defra, Mattilsynet, just released a statement re import of dogs, what they call “street dogs", defines as dogs from shelters/rescues, dogs without owners, dogs with unknown background.
1. These dogs will no longer be legal to commercially import.
2. As a private person, you must be able to document that the dog have been owned by you, and lived with you, for minimum 6 months before entering Norway.
Bascially, this means it is no longer possible to adopt/import a rescue dog from over seas effective from the 1st July 2018
