What is a “Standard”?
Breed standards are devised by breed associations or breed clubs, not by individuals, and are written to reflect the use or purpose of the species and breed of the animal. Breed standards help define the ideal animal of a breed and provide goals for breeders in improving stock. In essence a breed standard is a blueprint for an animal fit for the function it was bred – i.e. herding, tracking etc. Breed standards are not scientific documents, and may vary from association to association, and from country to country, even for the same species and breed. There is no one format for breed standards across all species, and breed standards do change and are updated over time.
In the Breed Standard, dogs are described in their general “ideal” appearance and, in more detail, in individual partsanatomical. Construction,movement, coat texture, neck or tail insertion and much more can also be specified.
The possible variants are listed (for example the various coat colors), the tolerances allowed (for example the minimum and maximum heights at the withers), but also the inadmissible defects, which lead (at least so it should be!) to exclusion from reproduction.
