Such well-mannered Retrievers! In this video, they are waiting in line to get their paws cleaned before going inside the house.
They wait patiently outside the front door. One behind another. Very orderly. They wait their turn to have their human wipe their paws before entering the house.
Watch how the 3rd dog lift his paw from the opposite side. Such coordination! He knows the routine. Notice how the dogs that have already entered the house wait just inside the door until ALL the dogs are done.
Wow, what polite dogs! Enjoy watching this amusing video.
