The AKS, commonly abbreviated as AKS or simply called King Shepherd, represents one of the newest developments in shepherd-type dogs, still considered a breed in development. The name 'King' reflects both the breed's impressive size and its intended status as an improved version of the German Shepherd, addressing health and temperament concerns while maintaining working ability. Some enthusiasts refer to them as King Shepherds or Kings, though these informal names lack the geographic designation that helps distinguish them from other shepherd varieties.
Developed in the United States during the 1990s, the breed lacks recognition from major kennel clubs like the American Kennel Club, though several alternative registries acknowledge them. The American Rare Breed Association (ARBA) recognizes the King Shepherd, providing a platform for exhibition and registration. Additionally, the breed can be registered with organizations including the American Pet Registry Inc. (APRI), Dog Registry of America Inc. (DRA), and the World Wide Kennel Club (WWKC), each maintaining their own standards and registration requirements.
The breed's development involved multiple shepherd-type dogs, leading to various descriptive names in breeding circles. Early development references included terms like 'Improved German Shepherd' and 'Super Shepherd,' reflecting breeding goals of creating a superior version of the traditional German Shepherd. Some breeders marketed them as 'Gentle Giant Shepherds' to emphasize their temperament advantages, though this terminology never gained official acceptance.
Internationally, the breed remains relatively unknown, with most recognition concentrated in North America where development occurred. The lack of standardized international recognition means naming conventions vary by region and registry. Some European enthusiasts aware of the breed refer to them as 'American Giant Shepherds' or simply 'Giant Shepherds,' though these names can cause confusion with other large shepherd breeds. The King Shepherd Club of America and the AKS Club work toward breed standardization and eventual major kennel club recognition, which would solidify naming conventions and breed identity globally.
