Hi Hannah,
You may want to try and put a shirt of yours in his crate with him at night so he can smell you. You can also put a small heat pack (they have them at the Petsmart) it is a little rice bag inside of a cute little stuffed dog. You just have to be VERY careful to make sure it isn't too hot. Also maybe the aromatherapy spray? I haven't used the spray but it may be worth a shot. GOOD LUCK to you!!
