From this bright start, disaster struck in the form of the two World Wars and many believed the breed to be extinct. People were so sure that this was the case that they closed the breed's stud book. In the 1950s and 60s, a few specimens of the breed were found and enthusiasts of the breed began working hard to re-populate it. With the increase of breeding, the Federation Cynologique Internationale accepted the breed in 1966. For many years, the breed's number continued to grow as people became re-introduced to the Nordic Spitz. However, with the introduction of foreign breeds into its native country, the Nordic Spitz has not flourished as its dedicated breeders had hoped.
