This is a funny, short clip of a dog that completely misjudged its ability to taking a running jump to get back onto the chair. As they do sometimes, these little guys got each other worked up with a look from each other. They run across the room and when they return the one that was on the chair, runs headlong into the chair. When it gets back up on the chair it has a look on its face like, “What?”
