The Giant Schnauzer
A well-bred Giant Schnauzer closely resembles the Standard Schnauzer—only bigger. As their name suggests, Giants are imposing.
A male might stand as high as 27.5 inches at the shoulder and weigh up to 95 pounds. The muscular, substantial body is, as the breed’s fanciers put it, a “bold and valiant figure of a dog.” The double coat is either solid black or “pepper and salt.” Familiar characteristics of the Mini, Standard, and Giant are a harsh beard and eyebrows, accentuating a keen, sagacious expression.

The Giant Schnauzer is a working breed of dog developed in the 17th century in Germany. It is the largest of the three breeds of Schnauzer—the other two breeds being the Standard Schnauzer and the Miniature Schnauzer. Numerous breeds were used in its development, including the black Great Dane, the Bouvier des Flandres, and the German Pinscher. Originally bred to assist on farms by driving livestock to market and guarding the farmer's property, the breed eventually moved into the city, where it worked guarding breweries, butchers' shops, stockyards and factories. It was unknown outside of Bavaria until it became popular as a military dog during World War I and World War II.
They have dense coarse coat that protects them from the weather and from vermin. Giant Schnauzers come in two color patterns: Solid black, and a color known as pepper and salt, with banded hairs of alternating white and black.
