The Giant Schnauzer is a larger, more powerful version of the standard schnauzer. Its body is strong, compact and nearly square, combining great power with agility. Its stride is free and vigorous, with good reach and drive. Its double coat consists of a soft undercoat and a harsh, wiry, dense outer coat — a combination that enables it to withstand harsh, alpine conditions. Its hallmark harsh beard and eyebrows, coupled with its smart outline, make for a striking figure. The combination of rugged build, reliable temperament and weather-resistant coat make for a powerful and versatile worker.

The playful, rambunctious giant schnauzer may be too boisterous for small children, even though it is otherwise very good with children in its own family. It is bold and protective of its family and reserved with strangers. It may be aggressive toward other dogs. This intelligent and exuberant breed is a good choice for an active person wanting a partner in adventure, although at times the giant may try to be the leader.
