This video is good for an "awww'" but it's also good for more than that. Can dogs learn? Of course they can! But can they teach? Many people would not grant them that ability. But in this cute video, the adult dog is clearly demonstrating to the puppy how to use the stairs. Not only is there nothing instinctive or natural about stairs, so each dog has to learn how to use them, but the adult dog knows how to demonstrate the proper technique, and when that doesn't work, resorts to applying a little bit of physical pressure.
