I once got downers for my Ruby and I will never use them again. It did not knock her out but the next day she was like a zombie.
Now, I spend the night in the laundry room with her. I turn the overhead exhaust fan on. If it's just a few hours, I sit there reading a book out loud. If it's for the whole night, I sleep on the floor with her. Whatever it takes, that's what I will do. Sam is not affected by the storms or loud noises, but he reacts to his bubby, Ruby being stressed out, so he spends the night with us. I do have a large laundry room.
