When your dog is afraid of almost everything

Does she like to play fetch a lot? Perhaps you could start throwing her favorite toys through the doorways for her to go after, until she gets used to it and doesn't worry so much about it anymore.

What happens when you carry her through the door? Maybe doing that a few times will help ease her anxiety.

Sometimes when our dogs were stressed out or worried, we would play some CDs with calming nature sounds, and it seemed to relax them too.
