Generally considered dogdom's finest all-purpose workers, German Shepherd dogs are large, agile, muscular dogs of nobile spirit and high intelligence. The breed has a distinct personality marked by direct fearless, but not hostile expression, self-confidence and a certain aloofness that does not lend itself to immediate and indiscriminate friendships. The German Shepherd Dog ​is a trotting dog, and its structure has been developed to meet the requirements of its work. The desired height for males at the top of the highest point of the shoulder blade is 24 to 26 inches; and for females 22 to 24 inches.  Weight for males 75-100 pounds, females 60-80 pounds.
