Cat or Dog?

The Puppy Bean has discovered that he is finally big enough to jump up onto the couches. The other day, I walked into the room and found this..... Normal dogs would just lay on the seat of the couch, but my freak of a puppy is up on the top like a cat in the sun. I also can't figure out how he got up there without knocking my lap top to the ground. I guess I shouldn't leave it sitting on the arm of the couch anymore.
