The breed standard for each breed of dog is distinct, giving a detailed "word picture" of the appearance and behavior of an idealized dog of that breed. Included in the breed standard description are externally observable aspects of appearance and behavior 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 as required by ResearchBreeder.com, 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.

Canine Cyclic Hematopoiesis: This disorder of the immune system occurs in gray collies. Puppies are usually smaller and weaker than their littermates and by 8 to 12 weeks of age they develop clinical signs such as fever, diarrhea or joint pain, or other signs associated with eye, respiratory, or skin infections.
The disorder is caused by an abnormality of the stem cells in the bone marrow, from which all blood cells develop. The result is a cyclic fluctuation in blood cell numbers, primarily neutrophils, which are very important in fighting infections. Every 10 to 12 days, the number of neutrophils drops dramatically, and then rebounds. There is increased susceptibility to infection corresponding to the dip in neutrophil numbers. As well, the normal activity of the neutrophils is impaired. These dogs are also prone to bleeding episodes due to the drop in platelet numbers.
