A German shepherd is a large, intelligent dog breed originally developed in Germany to herd and protect sheep. These dogs are strong and athletic, with pointed ears that stand straight up, a long snout, and a thick coat that's usually tan and black or all black.

German shepherds became famous for being quick learners and deeply loyal to their families. Because of their intelligence and trainability, they're often chosen as police dogs, search-and-rescue dogs, and guide dogs for people who are blind. When you see a dog helping an officer search for evidence or leading someone safely across a busy street, there's a good chance it's a German shepherd.

These dogs need lots of exercise and mental challenges to stay happy. A bored German shepherd might get into trouble, but one that gets regular walks, training, and attention makes a devoted companion. They're protective of their families without being needlessly aggressive, which is why they're one of the most popular dog breeds in the United States. The breed has appeared in countless movies and TV shows, from Rin Tin Tin in old Hollywood films to modern police dramas.
