Royal has known how to 'tidy up' for a long time. What we have been needing is a toy box with an attached lid. They just don't make them for small dogs! Yesterday I found a box in the dumpster that I could cut down and make work for us. He is now learning to open the box, tidy up and then close the lid. He needs a better understanding of closing the lid but I don't think it will take him long.
