German Shepherds are highly intelligent and agile dogs, with a strong work drive. They are often deployed in various roles such as police, guarding, search and rescue, therapy, service-dog, and in the military applications.

The breed has a personality marked by direct, fearless willingness to protect what it considers its "den" (i.e. house, car, and property in a home situation) and "pack" (i.e. human family in a home situation). It is poised, but when the occasion demands, eager and alert; both fit and willing to serve in its capacity as a companion, watchdog, guide dog for people who are blind, herding dog, or guardian, whichever the circumstances may demand.
