Schnauzers have been family and working companions since at least the 15th century. Of all Schnauzers, the Standard Schnauzer is the breed prototype, at about 18 inches tall and 35-45 pounds. High-spirited and devoted to his family, he is an energetic playmate who loves a good off-leash romp and playtime with his people. Your Standard Schnauzer puppy will grow up to be alert and naturally protective of his family. With keen intelligence, he can be a bit strong-willed, so plans on starting obedience training early. He thrives on lots of physical and mental stimulation and does well at many types of dog sports.
