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