All White Swiss Shepherd Dog Club of Australia (WSSDCA) Breeders adhere to the Australian National Kennel Council (ANKC) breed standard which following the Federation Cynologique Internationale (FCI) breed standard. A breed standard (also called bench standard or the standard) in the dog fancy is a set of guidelines covering specific externally observable qualities such as appearance, movement, and temperament for that dog breed. Breed standards are not scientific documents, but are written for each breed by clubs of hobbyists called breed clubs for their own specific requirements. Details and definitions within breed standards for a specific dog breed may vary from breed club to breed club and from country to country. Dog breed standards are similar in form and function to breed standards for other domesticated animals. The breed standard for each breed of dog is distinct, giving a detailed "word picture" of the appearance and behaviour of an idealized dog of that breed. Included in the breed standard description are externally observable aspects of appearance and behaviour that are considered by the breed club to be the most important for the breed, and externally observable details of appearance or temperament that are considered by the breed club to be unacceptable (called faults). In addition most breed standards include an historical section, describing the place of origin and the original work done by the breed or its ancestor types. However, breed standards do not include testing requirements for health, requirements for genetic testing, or requirements for specific types of training or work; breed standards are only intended to describe the breed's externally observable qualities. Breed clubs often make other requirements for health testing or work testing, but these are not covered in the breed standard itself.
