Hello, My name is Admiral and I left my mark!

I'm a four month old Great Dane and around 8:00 every night I like to run like a crazy dog around the living room. My usual circuit is around and around the coffee table at a galloping pace and then I start my sprints. I run quickly from one end of the living room to the other as fast as I can. Usually since I'm all legs and no coordination, I end up running really fast toward one end of the room, crash into the sofa and start toward the other end of the room where I flip over my bed, root around in it and head back for the sofa. Last night I hit the wall near my bed a little too hard and knocked a big fist-sized dent in it. Daddy was really upset about his wall, Mommy was really upset about me hitting the wall so hard and I was really upset they were now standing in my way! My exercise routine was over for the night and I wasn't finished! I think then they started talking about the time it would take me to be full grown and how someday I wouldn't have puppy energy any more.
