The Standard Schnauzer, once known as the Wire-haired Pinscher, the Mittelschnauzer (Medium Schnauzer) or simply the Schnauzer, is the oldest of the three distinct Schnauzer breeds (the other two being the Miniature Schnauzer and the Giant Schnauzer, which descend from the Standard Schnauzer). This is a working breed that is generally healthy, sound and long-lived. It is extremely intelligent, active and reliable and is especially good with children. As noted in an American Kennel Club publication, “Standard Schnauzers are not for those who want a slow, placid dog or one that can be fed and forgotten. Schnauzers insist on being part of family activities and develop best when treated in this manner. Outstanding companions known for their devotion and love of family, they are not one-person dogs but rather become true family members.” The American Kennel Club accepted the Standard Schnauzer into its Working Group in 1904.
The ideal height of a mature male Standard Schnauzer is 18½ to 19½ inches at the withers; bitches should be 17½ to 18½ inches in height. Males typically weigh 40 to 45 pounds, and females weigh 35 to 40 pounds at adulthood. The outer coat of this breed is tight, hard and wiry, with a soft undercoat. It must be salt-and-pepper or black in color. The American breed standard allows both cropped and natural ears in the show ring.
