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.

Dilated Cardiomyopathy: Cardiomyopathy refers to disease of the heart muscle tissue (the myocardium). In veterinary medicine, there are 3 main types of cardiomyopathy:
Dilated cardiomyopathy. This is by far the most common type in the dog, and is the subject of all the sections, below. With dilated cardiomyopathy, there is dilation of the chambers of the ventricles of the heart, caused by an inherent weakness in the muscle structure of the heart. The heart itself becomes enlarged, bloated, and unable to contract adequately, severely hampering the circulation. Hypertrophic cardiomyopathy. In this form of cardiomyopathy, there is a tremendous increase in the mass of the heart muscle tissue, with a resultant decrease in internal heart chamber size. While it is very common in the cat, hypertrophic cardiomyopathy is very rare in the dog. Restrictive cardiomyopathy. In this form of cardiomyopathy, the heart appears normal but infiltration of stiff, inelastic tissue within the walls of the heart severely restricts the heart's ability to fill adequately. Restrictive cardiomyopathy occurs with some frequency in cats but has never been identified in dogs. With any type of cardiomyopathy, the heart and circulation are forced to work harder to maintain blood perfusion to the organs of the body. If it is severe enough, cardiomyopathy may disrupt the circulation, causing fluid accumulation in the lungs and body cavities (congestive heart failure), or may give rise to erratic, unstable rhythms to the heartbeat (arrhythmias) that are potentially fatal.
