Query: Not sure if it works at all

One dog of ours has severe thunder/fireworks/firecrack phobia. We tried this wrap a few times in the summer and we weren't sure if it worked at all. All in all we didn't see any significant behavior improvements after using it. It only creates some psychological comfort on us to "perceive" it might work since we were pretty helpless and heart wrenching seeing her paralyzing panic during the stormy season.
