Would you let these guys sleep on the bed?

We hose the boys off when we get back to the boat launch area to get off the salty water and sand. Then a good toweling to dry them somewhat.....They are always very pooped from all the swimming and head straight for the bed for a long nap. Despite all the freshwater rinsing/toweling, the spots where they were sleeping are thick with sand! Their coats really soak up ALOT of sand!
