Novice Scottiedog asks, "What is the difference between a workdog and a playdog?"
Scottiedog Master: "They are the same. That is the difference."
(Author's note: Tallie Alexander's sons, at one point, called their Grandma Roxie's dog, Muffin, a "workdog." Roxie liked this; and the term has always seemed to me an excellent one ... even if the finer nuances of its childhood meaning might escape me.)
