Being a dog person, I totally understand. I even did the same thing once--just to make a friend laugh. I told my friend's daughter to give the dish she had used to the dog to lick. When the dog finished, my friend's daughter asked where the dish should go (as in sink or dishwasher) and I said, is it clean? put it in the cabinet. That poor girl did not know what to do--
skip ahead to now, to "rinse" my dishes, I simply call "rinse cycle" and both dogs come running. Sometimes, they simply wait by the dishwasher as I am clearing the table.
