I have a 7-year-old beagle and she whines every night waking me up. She only does this when she is sleeping with me, not any other person in my house. How can I make her stop?

Ignore her. You will lose sleep for a while, but completely ignore her. Assuming she doesn't need to pee, when you wake up, say "no" firmly. If she continues, completely ignore her. If the only person she is doing this to is you, it means she knows you will do something (pet her, sweet-talk her, etc.) that she enjoys. If she receives either no attention or only negative attention (i.e., the word "no" or a scruff shake if she tries to jump on your bed), she'll stop. It'll likely take a week or two to stop the problem if you're consistent. Consistency is key.
