Large vintage pottery terrier dog figurine, McCoy?

Take a look at this wonderful vintage dog figurine. It measures 7 1/2" tall and has a soft low sheen glaze with black cold paint accents on the nose and eyes. Not sure which kind of terrier he is, A scotty, wire hair, or maybe an airdale puppy. He is adorable though. A little wear on the cold paint on his nose. No chips or cracks. He looks like McCoy though, but there are no markings of any kind, and could be some other old pottery company. A must have for dog colectors.
