German Shepherd Dogs were shaped in Germany around 1900, when cavalry officer Max von Stephanitz set out to standardize the country's varied sheep-herding dogs into one capable, intelligent working breed. The result is a strong, agile dog that is longer than tall, with erect ears, a long muzzle, a bushy tail and a dense double coat, most often black and tan, black and red, sable or solid black.
Many German Shepherds are devoted to their families, quick to learn and naturally watchful, which is why they work so widely in police, military, search and assistance roles. That same drive means a GSD usually needs a job: daily exercise, ongoing training and real time with its people. Many are reserved with strangers, and some become overprotective without thoughtful socialization, so a calm, confident adult can be an excellent match for an adopter.
