Two of my 4 dogs are afraid of storms and firecrackers. The thunder shirts did not work for us. Our dogs can sense when a storm is coming so we get ready for it before they get out of control. We close the curtains. We sit on the sofa with them and watch TV with the volume turned up a little more than usual. They can't see the lightening, they can't hear the thunder as well either. They sit close to us and we pet them running our hand down from the top of their heads all the way down to their tails. It soothes them. We have tried drugs from the vet but decided to not give medications any more. Our vet says he has seen huge dogs practically tear down doors they are so frightened. Hope this helps. Peanut10
