Start them early...

Two little Dawgs doing a little cleaning

I just asked them to pick up a few pieces of food under the table.  We have been working on having them work together to set the table and clean it off.  The next thing I know everyone has some sort of broom and they swept my whole kitchen.  Gotta love that!!! (I'm just happy that the boys didn't use the brooms as weapons!)  Progress!
