The German Shorthaired Pointer (GSP) is a medium to large sized breed of dog developed in the 19th century in Germany for hunting. A versatile hunting breed, being an all-purpose gun breed of dog suitable for both land and water, she is streamlined yet powerful with strong legs that make her able to move rapidly and turn quickly. She has moderately long floppy ears set high on the head. The tail is commonly docked, although this is now prohibited in some countries. They are playful and have much energy. German Shorthaired Pointers requires a great deal of physical and mental exercise. When meeting other dogs they get along well, especially when they are similar size. The 1978 film 'Days of Heaven,' written and directed by Terrence Malick, features a brief scene of dogs hunting the prairie. The GSP shown is Jocko von Stolzhafen, twice GSP National Champion (Field) and perhaps the best GSP of his era. A year or so later Jocko vanished while running at a training camp, presumably stolen.
