The Jämthund derives from a large hunting spitz found in the Forest region of the North barrier of Scandinavia and Russia. These spitzs’ probably came with the hunting tribes that migrated to Sweden thousands of years ago. Two types of wolf coloured spitz have been recognised in Scandinavia. The Norwegians decided in 1877 that the smaller was to be called Norwegian Elkhound. The large variety that was mainly known in the Swedish county of Jämtland did not match the standard for Elkhound on several points, especially not for size.

Breed club surveys
There are numerous breed standards. The basis of breed/conformation shows is the judging of pedigree dogs against the 'Breed Standard', which is a picture in words that describes the range of features that are deemed appropriate for the breed.
The Kennel Club list of DNA tests available for each breed along with an indication as to whether the test is part of the Assured Breeder Scheme (recommended or required) and whether it is recorded on the Kennel Club registration database.
