Finally I'm figuring this out. All these years living with us and Elke finally has a job. Elke is awesome at cleaning up food messes. Tonight I took Landon out of the high chair after supper, shook him out and set the tray on the counter top. Well, the tray fell, but have no fear, Elke to the rescue! Elke licked the tray and the floor clean. All I had to do was throw the tray in the sink to wash it up and we were on our way. What a good dog!
