he plays with flour, i get burned

This afternoon I learned the following:
-Do not leave a bag of groceries on the floor and then leave the house (even if it only contains canned goods, flour, and rice) when you have a dog.
-At least one dog I know doesn't mind inhaling flour and uncooked rice.
-Dogs do not digest uncooked rice very well.
-It is incredibly irritating trying to clean a rug with flour embedded in it.
-It is incredibly irritating cleaning flour paw prints on the floor, sofa, and comforter.
-When flour and water mix, it sticks to fur really well.
