"We are absolutely ASTOUNDED at how WELL this works! After only 2 uses, our dog is able to stay home alone with no more medication, no drooling, upset stomach & no howling! He actually likes the shirt & gets excited when we get it out to put on him! We were a bit skeptical, but now are telling EVERYONE!"

"Our Blue Girl is DEATHLY afraid of thunderstorms, fireworks, loud motorcycles, ANYTHING that makes a loud noise. The ThunderShirt works so well - I truly believe it is the BEST thing that money can buy. Thank you!"

We put the ThunderShirt on our dog for the first time when we were traveling. She went from barking and very anxious to walking around quietly and peacefully, instantaneously. I was surprised to set it work right before my eyes. This shirt is a well-made quality product, get this brand. It’s worth it.

"ThunderShirt is worth more than its weight in gold. For 12 years, my Cairn terrier had turned into a groveling, panting mess at the first sound of thunder. We'd tried everything, and nothing helped. With the ThunderShirt, we've seen immediate and consistent results. It's literally a miracle. Even in the midst of a killer storm, my little man was able to find peace."
