DOG FAQ - Aren't there different sizes for the Schnauzer?

The Miniature, Standard, and Giant Schnauzers are distinct breeds though their conformation is very similar. The Standard Schnauzer was bred to keep the vermin population down on the farm, herd and guard the farm. The Giant Schnauzer was bred to do all those things plus pull carts and also has been used for police work. The Miniature, Standard, and Giant Schnauzers have similar but distinct personalities.
