The Giant Schnauzer is a working breed of dog developed in the 17th century in Germany. It really is the largest of the three strains of Schnauzer—the other two strains being the Standard Schnauzer and the Miniature Schnauzer. Numerous strains were used in its development, including the German Pinscher, the Bouvier des Flandres, and the black Great Dane.
Originally bred to help by driving livestock to market and safeguarding the farmer’s property, the strain eventually moved into the town, where it worked guarding breweries, butchers’ shops, stockyards and factories. It was unknown outside of Bavaria until it became popular as a military dog.
They have dense rough coat that protects them from vermin and from the weather. Giant Schnauzers come in two color patterns: Solid black, and a shade known as salt and pepper, with banded hairs of alternating black and white, seeming gray hairs at a space.
