German Shepherds have a double coat which is close and dense with a thick undercoat. Hektor was the product of few generations of selective breeding and completely fulfilled what Von Stephanitz believed a working dog should be. He was pleased with the strength of the dog and was so taken by the animal's intelligence, loyalty and beauty, that he purchased him immediately. After purchasing the dog he changed his name to Horand von Grafrath and Von Stephanitz founded the Verein für Deutsche Schäferhunde (Society for German Shepherd Dogs). Horand was declared to be the first German Shepherd Dog and was the first dog added to the society's breed register. Many common ailments of the German Shepherd are a result of the inbreeding practiced early in the breed's life. One such common ailment is hip and elbow dysplasia which may cause the dog to experience pain later on in life and may cause arthritis. A study conducted by the University of Zurich.
