We propose to define by picture and measurement the features that distinguish the different coat types of the most common breeds of dogs as recognized by the AKC. We do not know how the coat of a Whippet differs from a Beagle or what makes the coat of one dog better than another. In addition, defining normal in terms of number and diameter of hairs per unit area can be used to assess the severity of diseases with hair loss. This knowledge will allow veterinarians to make a definitive diagnosis of some diseases without the need for biopsy or laboratory tests. Finally, data obtained in this proposal can serve as a means of breed identification. A DNA bank of different canine breeds will also be assembled to provide a resource to further understanding of the canine genome and its diseases.
