About the painting - by Daniela Ria:

Medium Salz und Pfeffer Schnauzer with Renaissance clothes – Germany – its origin is uncertain. The standard Schnauzer is the original breed of the three sizes of Schnauzer, although it is sometimes classified as a terrier. The breed is a handsome, robust, squarely built, medium-sized dog with aristocratic bearing, making it a popular subject of painters Albrecht Dürer and Rembrandt.
