Leave your dog in its dog house when it's time for you to go to bed. Lock your dog in its crate! Leave a small bowl of water where it can reach it at night. Small enough that if it spills it doesn't ruin the crate but big enough that the dog can get a drink, even dogs get thirsty at night. Many dogs need to go out at night, so keep the dog close enough to you that you can hear it if it barks. Another reason to keep it close is to make it feel like part of the family. If you don't keep it close it can be nervous as it feels it has no protection.
