There are three size variants of schnauzer: giant, standard, and miniature. As their name suggests, the giant schnauzer is the largest among these. This breed was developed in Germany during the 1800s and was originally bred to serve as a working animal. Their most popular job was to protect livestock and other assets, but later on, some served in the military and on the police force. Since this time, they have become more popular as companion animals or show dogs.
