German dogs, Schnauzers come in three sizes (Giant, Standard, and Miniature) and were initially bred to catch rats and other pests outdoors. Today, Schnauzers thrive on human companionship and are extremely intelligent and naturally obedient, making them easy to train. Schnauzers are proud and independent dogs, and are loving towards their owners. They make wonderful watch dogs and are highly energetic.
The German army used Standard Schnauzers as dispatch carriers and Red Cross aides during both World Wars.
The Standard Schnauzer originated in Germany around the Middle Ages.
