They are little climbers. That's for sure. I've never had trouble with mine doing that, but I know plenty of people who have!
Perhaps you could get a big crate. I know I've seen them. I always just watched them like hawks until they were housebroken. P.S. I take mine with me and go for walks instead of jogging. Perhaps you could try to include him in your activities more, so that he could get out and empty up?
