The Standard Schnauzer is the original of the three Schnauzer breeds. It was developed in southern Germany as a farm dog that caught rats, guarded the yard and rode along with carriages, and the Miniature and Giant Schnauzers were later developed from it. A wiry pepper-and-salt or black coat, bushy eyebrows and a bearded muzzle give it a serious look, though many are playful at home.
Standards are medium-sized and sturdy, usually 30 to 50 pounds. Many are loyal, alert and reserved with strangers, with a strong will and a real prey drive, so consistent training matters. The wiry coat needs brushing and hand-stripping or clipping every six to eight weeks, and the beard needs drying after wet walks. Dogs vary, so judge each one by its own personality.
