German Shepherds are large sized dogs. They have a domed forehead, a long square-cut muzzle and a black nose. The jaws are strong, with a scissor-like bite. The eyes are medium-sized and brown with a lively, intelligent and self-assured look. The ears are large and stand erect, open at the front and parallel, but they often are pulled back during movement. They have a long neck, which is raised when excited and lowered when moving at a fast pace. The tail is bushy and reaches to the hock.
German Shepherds were bred specifically for their intelligence, a trait for which they are now famous. 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. Coupled with their strength, this trait makes the breed desirable as police, guard and search and rescue dogs, as they are able to quickly learn various tasks and interpret instructions better than other large breeds.
German Shepherds have a variety of colors, the most common of which are tan/black and red/black. Most color varieties have black masks and black body markings which can range from a classic “saddle” to an over-all “blanket.” Rarer colour variations include the sable, all-black, all-white, liver and blue varieties. The all-black and sable varieties are acceptable according to most standards.
German Shepherds are a popular selection for use as working dogs. They are especially well known for their police work, being used for tracking criminals, patrolling troubled areas and detection and holding of suspects. Additionally thousands of German Shepherds have been used by the military. Usually trained for scout duty, they are used to warn soldiers to the presence of enemies or of booby traps or other hazards. German Shepherds have also been trained by military groups to parachute from aircraft or as anti-tank weapons. They were used in World War II as messenger dogs, rescue dogs and personal guard dogs. A number of these dogs were taken home by foreign servicemen, who were impressed by its intelligence.

The German Sheperd is prone to hip and elbow dysplasia which may lead to the dog experiencing pain in later life and may cause arthritis. Some may suffer from degenerative spinal stenosis.
