German Shepherds are medium to large-sized dogs. The breed standard height at the withers is 60–65 cm (24–26 in) for males, and 55–60 cm (22–24 in) for females. German Shepherds were bred specifically for their intelligence, a trait for which they are now famous.[6] In the book The Intelligence of Dogs, author Stanley Coren ranked the breed third for intelligence, behind Border Collies and Poodles. He found that they had the ability to learn simple tasks after only five repetitions and obeyed the first command given 95% of the time. German Shepherds are moderately active dogs and are described in breed standards as self-assured.The breed is marked by a willingness to learn and an eagerness to have a purpose. They are curious, which makes them excellent guard dogs and suitable for search missions.
