separation anxiety at night

Question
We have a 9 year old female springer spaniel we got from the pound 2 years ago. I know she had a hard life and is afraid of everything. She only likes me. My husband is nice to her pets her and gives her treats but for whatever reason she still is afraid of him. The problem is every morning around four or five am she starts pacing up and down the hall outside her bedroom. Her toenails on the laminate floor drive both of us crazy. I don't pet her or reward her for this behavior (I only tell her to lay down and stay on her bed) The only way to get her to lay down and be quiet is for me to sleep on the couch near her bed. I've tried closing the door of the room she sleeps in (next to mine)
but she just throws herself against the door. I've tried putting her in the garage but then she just barks. She is afraid of thunderstorms so one night I put her in the bathroom and she still is afraid to walk in that room (6 months later) She is terrified of a crate. I've tried putting treats in and she won't even go in and get them. I don't want to give her back to the pound but am so tired from never sleeping. And the weird thing she doesn't have anxiety when I leave her home alone It makes no sense. She won't sleep in our bedroom because she is afraid of my husband.
Any help you can give would be welcome Thank you.

Hi Kathyrn. Ask your husband to please ignore the dog for a while.  No attempts at petting and no eye contact.  She's got to learn to trust him on her own terms, not on a timetable.  Instead, what your husband CAN do is to carry high value food treats (tidbits of meat, cheese, soft dog treats no bigger than a pea) with him around the house.  Each time he walks past the dog, he should drop a treat and keep going.  No eye contact or conversation, just treat delivery guy.  He should stay at enough of a distance that she doesn't shy away - toss the treat if necessary.  She'll soon come to look forward to his approach and learn that he's a good guy and not a threat.  

I would suggest allowing her to sleep in your room on your side of the bed, on her dog bed.  Have your husband get in bed first, turning away if necessary, then allow the dog in and have a treat on the bed for her.  Dogs really want to be with their pack, especially at night, so give her a chance to learn that this is a safe time to be in the room with your husband.  Don't ever close a door on a fearful dog alone in a small room.

I'd like to suggest 2 products to you for anxiety:  (1) www.thundershirt.com and (2) a supplement called ProQuiet that you can google and find online.  Other things that you can investigate are Rescue Remedy, and Comfort Zone DAP products.

Please let me know if you have questions or need clarification on anything I've recommended.  I'd love to hear how this goes, so please feel free to follow-up after you've had a chance to try some of the suggestions.  Good luck!
