Be really careful in using his crate as a place of punishment. If it's not done correctly, it could backfire on you later if you need him crated later on in life for any reason. You want Bob to understand his crate is a great place and his santuary and good things happen in the crate.

Keep up the good work! Remember to enroll him a puppy kindergarten class. He is the perfect age right now!
