Schnauzer

The Schnauzer is one of the Great Dane breeds. In the FCI classification it was included in the II group. 
It is basically a dog that comes in three different sizes. The miniature schnauzer is the smallest. The 
medium schnauzer is apparently larger and the giant schnauzer is the largest. Each of the aforementioned 
animals is a descendant of dogs that lived in Germany and Switzerland centuries ago. They were used for 
guarding, exterminating rodents and guarding horses.
