First employed as a cattle dog, the Giant Schnauzer became popular as a guard dog in Germany and Great Britain. Because the Giant Schnauzer is obedient and easy to train, across Europe he is used as a police dog. The beard and mustache of the Giant Schnauzer suggest a threatening look, which can have a deterring effect on even the worst of criminals. The coat of the Giant Schnauzer requires regular trimming, and despite his size, he doesn’t eat much. The Giant Schnauzer makes an excellent pet and loves to be part of a family.
