End note: The Smooth Fox Terrier is the epitome of "what you see is what you get." If the handler must show the Smooth to you "hands-on," the essence of the breed is lost in that exhibit. Smooths portray the basic nature of the proud, "take me or leave me," I can do it by myself Terrier. Judge them on their own merit. The handlers that makes themselves observable to the judge do the exhibit worthy of notice no favor.
