I agree. Our vets office even has a sign out for Halloween letting people know they might want to consider this on this very busy night. It's not good for them to get all stressed out. We used to have a dog that wouldn't go up or down stairs for anything but when the thunder came she headed to the basement to hide. Her fear of thunder out weighed her not liking stairs. I know some dogs that go under a bed or table. Talk to your vet.
