I made a version of the ThunderShirt on Monday afternoon for my rescue chocolate lab. I went to the online store to see just what it looked like and made my own. Storms came that night until 4am, had his shirt on and was calm all night. I got a pair of 95%cotton/5% spandex pants to match his fur.
I did order a real Thundershirt but needed one Monday night---it WORKED great. He went to the vet the next day for his heartworm and shots, was calm in the car and at the office.
I will return the real shirt because it is just t-shirt knit shaped to the dogs body. Next I will make one for my black lab/beagle using a black pair of pants or t-shirt. Two hours of pattern making and sewing was well worth it.
Both will have their 'shirts' on tonight when the next round of storms come to the Mitten state.
