I tried EVERYTHING in the 10 years we had Buddy. The only thing that worked, which I found two years ago, is the Calming Collar. If I hadn't seen it, I would not have believed it, but it works for thunder, fireworks, etc. He was still afraid, but I could get him to stop pacing and lay down to get through the storm, etc. www.calmingcollar.com
Good Luck.
