We have had many mixed breeds on Dog of the Day, but the one that stands out in my mind as an unlikely combination was the Shih Tzu/ Golden Retriever mix, Maxwell - see http://DogoftheDay.com/archive/2000/March/09.html . Some people thought he was so cute, they wrote us asking where they could get one just like him! A lot of mixed breeds, of course, come from shelters and have that mysterious past, so we guess!
