My dog is a 1 year and three month old Pomeranian. She still has a tendency to whine at night and I don't know why. She gets two 20 minute walks a day and every other night she gets an hour of play at the dog park. Any suggestions on why she whines/how to make her stop? Also, what time does your dog go to bed?

No, she sleeps alone in her crate. I am considering getting her a companion but right now I am unable to. Maybe some time in the future?
