Before entering into the house these 4 brilliant canines know that they must get their paws cleaned. So they patiently wait at the front door in an orderly queue, one behind the other. Remarkably there is no queue-jumping or jostling. Dogs lift up each foot to be thoroughly cleaned with a towel. The dogs that have gone first stand at the doorway looking out as the final retriever joins them.
