In German Shepherd Dogs the recessive gene for white coat hair was cast in the breed gene pool in the late 19th and early 20th century breeding program that developed and expanded the German Shepherd Dog breed in Germany. A white herding dog named Greif was the grandfather of Horand von Grafrath, the dog acknowledged as the foundation of all contemporary German Shepherd Dog bloodlines.
Information provided in early books on the German Shepherd Dog make mention of Greif and other white German herding dogs, with upright ears and a general body description that resembles modern German Shepherd Dogs, shown in Europe as early as 1882. The early 20th century German Shepherd breeding program extensively line bred and inbred "color coat" dogs that carried Greif's recessive gene for "white coats" to refine and expand the population of early German Shepherd Dogs.
White coats were made a disqualification in the German Shepherd Dog Club of Germany breed standard in 1933 after the breed club came under the control of the German Nazi party. The German breed standard remained unchanged as German breeders repopulated the breed in the years after the conclusion of World War 2.
During the 1970s, white dog fanciers in the United States and Canada formed their own "White German Shepherd" breed clubs, breeding and showing their dogs at small specialty dog shows throughout North America. These dogs were then exported to Europe and would go on to become the foundation of the White Swiss Shepherd breed.
On 1 January 2003 the FCI officially recognised the White Swiss Shepherd as own breed with the standard no. 347. The country of origin "Switzerland" just results to the fact that the Swiss breed club officially requested the breed to be recognised with the FCI.
