Behavior

German Shepherds are a popular selection for use as working dogs. They are known for being easy to train and good for performing tasks and following instructions. 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 their intelligence.

The German Shepherd is one of the most widely used breeds in a wide variety of scent-work roles. These include search and rescue, cadaver searching, narcotics detection, explosives detection, accelerant detection and mine detection dog, among others. They are suited for these lines of work because of their keen sense of smell and their ability to work regardless of distractions. At one time the German Shepherd was the breed chosen almost exclusively to be used as a guide dog for the visually impaired. When formal guide dog training began in Switzerland in the 1920s under the leadership of Dorothy Eustis, all of the dogs trained were German Shepherd females. An experiment in temperament testing of a group of Labrador Retrievers and German Shepherds showed that the Retrievers scored higher on average in emotional stability, ability to recover promptly from frightening situations, cooperative behaviour and friendliness; while the German Shepherds were superior in aggression and defensive behaviour. These results suggested that Labrador Retrievers were more suited to guide dog work while German Shepherds were more suited to police work. Currently, Labradors and Golden Retrievers are more widely used for this work, although there are still German Shepherds being trained. In 2013, about 15% of the dogs trained by Guide Dogs of America were German Shepherds, while the remainder are Labrador Retrievers and Golden Retrievers. The Guide Dogs for the Blind Association in the United Kingdom trains some German Shepherds, while the comparable organisation in the US only trains Labrador Retrievers, Golden Retrievers and crosses between these breeds.

German Shepherds are still used for herding and tending sheep grazing in meadows next to gardens and crop fields. They are expected to patrol the boundaries to keep sheep from trespassing and damaging the crops. In Germany and other places these skills are tested in utility dog trials also known as Herdengebrauchshund (HGH) herding utility dog trials.

The German Shepherd is obedient, unfailingly loyal, and has an excellent sense of smell. He is lively, eager, and highly trainable because of his desire to obey. The breed has a personality marked by direct, fearless willingness to protect human children. The ideal dog is a working animal with an incorruptible character combined with body and gait suitable for the arduous work that constitutes its primary purpose.

Early training is vital. This is an active dog with a need for space and exercise, but can live in an apartment in the city if walked daily. This breed does not like to be alone and cannot tolerate being closed inside all day. Brushing twice per week is required. In a litter, it is wise not to select the overexcited or fearful puppy because he could become aggressive.

Behavior

In nature, the Great Pyrenees is confident, gentle (especially with children), and affectionate. While territorial and protective of its flock or family when necessary, its general demeanor is of composure and patience and loyalty. It is a strong willed, independent and reserved breed. It is also attentive, quite fearless and loyal to its duties. The Great Pyrenees' size makes it an imposing guardian. A dog of this breed will patrol its perimeter and may wander away if left off its leash in an unenclosed space. The Great Pyrenees protects its flock by barking, and being nocturnal, tends to bark at night unless trained against such behavior.

The Great Pyrenees can be slow to learn new commands, slow to obey, and somewhat stubborn to train. Despite this relative stubbornness, it is quite unusual for the Great Pyrenees to become aggressive or turn on its master. It is wary of strangers if the person is not allowed in the house, but will settle down if the owner of the dog seems comfortable with the stranger. This dog was originally bred to be a livestock guard dog, and can still be found doing that job on farms and ranches.

This dog is not suited to city living. He needs exercise and room to run, or he will develop behavioral problems. He does not like to be shut in. Brushing three times per week and bathing several times per year is required.
