My lab is named Shadow. When he was a little puppy, we would put him in the utility room in the basement, because he wasn't quite housetrained yet. In order to keep him out of the anti-freeze, and other chemicals stored in the room, we split the room with piece of chain link fence. First time we put him in there, we got home to find him on the other side. Keep getting over, and we couldn't figure out how he was doing it, untill one day we got home, went to let him out, and caught him halfway climbed up the fence.
Of course, he's 10 years old, now, and a big fat old dog. Spoiled rotten, too. Can't ever leave a plate sitting unwatched on the table, or he will get it.
