What is the Difference Between the Different Types of ThunderShirt®?

While we have several different styles and colors of ThunderShirt®, they all may have the same calming effect for your dog!  Each style of ThunderShirt® is lightweight, machine-washable, and breathable, and they all help your dog to feel calmer during fireworks, thunderstorms, travel, vet visits, and more!  They are all equally as effective, so you cannot go wrong with your choice!

Please see our ThunderShirt® for Dogs Instruction Sheet for additional information on how to use the Heather Gray, or Sport Styles.

If you purchased one of our Polo styles, please see this instruction sheet.

On instructions for how to put on a ThunderShirt®, please see the videos on this page.  Please note that the Polo styles go on differently than the Classic and Sport, so make sure to check out the right video!

How Do I choose the Right Size ThunderShirt®?

In general, if your dog is right on the cusp of the weight range indicated in our size chart, we would recommend that you size down. However if you are looking at one of our polo styles, those tend to run smaller, so we would recommend sizing up if you are interested in the polo style ThunderShirt®.

Sizing can be tricky – do not hesitate to give us a call at (866) 892-2078 and we’d love to make sure you find the right size for your pet.

But I’m looking for a Thunder Jacket…

From Chihuahuas to Great Danes, millions of dogs are already using ThunderShirt®. Yours could be next – we can’t wait for you to be part of the ThunderShirt® family!
