Since this thread has been revived I will add my story.
I had a bay tobiano Spotted Saddle Horse (Dewey), and a double pattern varnish roan/blanket with spots Appaloosa (Elwood). 005_5 dewey and elwood spotted horses.jpg
When people would come to see them, many would say they liked the spotted one. I had them both for some years. I thought most people were familiar with the term Appaloosa. So at first I would think they were talking about Dewey-the SSH, but no it was random.
As time went on my response became: "The one with the big spots, or the little spots?" LOL
