Some animals are a little more cautious than others. This dog is probably on the side of TOO cautious.
He is a bit terrified of the slippery floors, so after spending several moments crying at the end of the hall his dad has to lead him to the carpet. When he gets there, his method to make it the rest of the way is pretty adorable. He turns around and takes advantage of his rear wheel drive! I guess sometimes going in reverse has its advantages!
