Hair length is one of the most important morphological traits in many dog breeds. Differences in coat length are visible in various dog breeds, but for some, the breed standard allows only one coat length. In some breeds, long or short variant is inacceptable. One such example is Pembroke Welsh Corgis where longhaired dogs (also called "fluffies") are inacceptable.
