Our Golden Retriever from Turkey has a really bad fear of thunder or loud noises. When storms roll through she goes bananas running around the house looking for somewhere to hide. We have found great success using the Thundershirt to calm her down. She gets excited when she sees it pulled out and practically jumps into it. 9 out of 10 times she calms right down and falls asleep. The last 10% of the time is usually due to the storm being especially bad and right overhead.
