Summarize this article:

The German Shepherd is part of the working dog classification and has a strong proportioned build. Typically, the German Shepherd is 22 to 26 inches (50-65 cm) tall and weighs between 77 and 85 pounds (35-40 kg). It has a narrow and deep chest, and the front legs and shoulders are muscular and sloping. Its body is slightly longer than it is deep, measuring from the shoulders to the rump. German Shepherd puppies typically weigh 7-9 pounds (3-4 kg) after the first month and will continue to grow steadily throughout their first year. By six months they will weigh approximately 50-57 pounds (22-26 kg). German Shepherds have very distinct pointed ears that are erect. They are long at the base and face forwards, making the shape of a triangle. As puppies, the tips of the ear may flop over slightly, but they will straighten as the dog ages. German Shepherds have a long and bushy tail that hangs down when the dog is resting. When a German Shepherd is alert or in motion, the curve of the tail is accentuated and the tail will be slightly raised.
Examine the dog's strong build. Look for pointed ears. Notice the bushy tail.
