Original Terrier Dog Figure

This is a figure of a dog (I believe it is some sort of terrier but I stink at IDing dog breeds) made by Nymphenburg in the early 20th century. A rare original period piece which is signed by the artist! He is superbly modeled and painted just right to make him very elegant. The dog is 5.125 inches tall, 2 inches wide and 6.5 inches long. Marked with the impressed shield mark underneath on his belly with the number 651 impressed under one paw and 9 under the other. Also the artist initials R.B. which I am fairly sure has not been identified. He is in perfect condition. Please email me for more information or other pictures.
