PMID 26754411.In the 1800s those interested in the sport of dogs developed a system for classifying breeds according to their functions. The British classification, established in 1873 and revised periodically by the Kennel Club of England, set the standard that other countries have followed, with some modifications. British, Canadian, and American classifications are basically the same, although some of the terminology is different. For example, Sporting dogs in the United States are Gundogs in England. Utility dogs in England are Non-Sporting dogs in the United States and Canada. Not all countries recognize every breed. Ahmed Zihni (2004). "Dog Meat Dilemma".
