You poor thing. Sounds like you've got a handful. Hang in there, and it will get better as he ages. Guaranteed. Here's a couple things to try:

* Increase the exercise. I realize you don't have much time, especially right now, but if you could do two 20-30 minute walks or runs a day, it will help. If you can find another dog to play with in a fenced yard on occasion, that will help even more. They can wear each other out.

* Chew toys. Get something, or several things, that he likes to chew on. Bully sticks are great. Nylabones. Kongs.

* Crate train. This may be tough at first, but read up on crate training if you haven't already done that. If you can get him comfortable in his crate, then you can get some time for yourself and your exams.

Good luck. And remember. Reward good behavior. Ignore bad behavior.
