German Shepherds are a large sized dog which generally are between 55 and 65 centimetres (22 and 26 in) at the withers and weigh between 22 and 40 kilograms (49 and 88 lb). The ideal height is 63 centimetres (25 in), according to Kennel Club standards. 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 sport a double coat. The outer coat, which is shed all year round, is close and dense with a thick undercoat. The coat is accepted in two variants; medium and long. The long-hair gene is recessive, making the long-hair variety rarer. Treatment of the long-hair variation differs across standards; they are accepted under the German and UK Kennel Clubs but are considered a fault in the American Kennel Club.German Shepherds can be a variety of colors, the most common of which are the tan/black and red/black varieties. Both 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; however, the blue and liver are considered to be serious faults and the all-white is grounds for instant disqualification in some standards.
German Shepherds were bred specifically for their intelligence, a trait for which they are now renowned. They are considered to be the third most intelligent breed of dog, behind Border Collies and Poodles.In the book The Intelligence of Dogs, author Stanley Coren ranked the breed third for intelligence. 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 Shepherd Dogs are among the top five most popular dogs in the United States according to American Kennel Clubstatistics and well-trained and socialized German Shepherd Dogs have a reputation among many as being very safe (see Temperament section below). In the United States, one source suggests that German Shepherd Dogs are responsible for more reported bitings than any other breed, and suggest a tendency to attack smaller breeds of dogs.
An Australian report from 1999 provides statistics showing that German Shepherd Dogs are the third breed most likely to attack a person in some Australian locales.
However, the Centers for Disease Control and Prevention, which advises on dog bite prevention and related matters, states "There is currently no accurate way to identify the number of dogs of a particular breed, and consequently no measure to determine which breeds are more likely to bite or kill."
Similarly, the American Veterinary Medical Association through its Task Force on Canine Aggression and Canine-Human Interactions reports, "There are several reasons why it is not possible to calculate a bite rate for a breed or to compare rates between breeds. First, the breed of the biting dog may not be accurately recorded, and mixed-breed dogs are commonly described as if they were purebreds. Second, the actual number of bites that occur in a community is not known, especially if they did not result in serious injury. Third, the number of dogs of a particular breed or combination of breeds in a community is not known, because it is rare for all dogs in a community to be licensed, and existing licensing data is then incomplete."Moreover, studies rely on 'reported' bites, leading the National Geographic Channel television show The Dog Whisperer to conclude that small dog breeds are likely responsible for more bites than large dog breeds, but often go unreported.
In addition, according to the National Geographic Channel television show, Dangerous Encounters, the bite of a German Shepherd Dog has a force of over 238 pounds (compared with that of aRottweiler, over 265-328 pounds of force, a Pitbull, 235 pounds of force, a Labrador Retriever, of approximately 125 pounds of force, or a human, of approximately 170 pounds of force).Regardless, one source indicates that fatalities have been attributed to over 30 breeds since 1975, including small breeds, such as the Pomeranian.
