The Giant Schnauzer developed in Germany. Schnauze means muzzle in German, so this breed was named for its characteristic shaggy muzzle.The Giant Schnauzer is thought to be the result of crossbreeding of the Standard Schnauzer, the Great Dane, and the Belgian Cattle Dog. But the Giant Schnauzer may simply be an enlarged model of the Standard Schnauzer.Originally cattlemen used the breed to drive their cattle to market when the cattle driving died ou they were then used as guard dogs. They trained as police dogs, and continue in this role in many European countries today.
