How It Started
Thundershirt's founder's dog, Dosi, is a 10-year-old, 50-pound mutt who is very lovable and will make friends with anyone. But Dosi was a nightmare with loud noises… thunderstorms, 4th of July, etc. Even when the skies were clear, her family would know that a thunderstorm was coming by Dosi’s behavior. When a storm was approaching, Dosi’s tail went between the legs and the shakes began. If it was during the night, she would keep her family awake for hours. They visited three different veterinarians over the years to find a remedy. The only suggestion was to sedate Dosi, but even the veterinarians didn’t think drugs were an effective solution. You had to anticipate the storm by 1-2 hours for the sedatives to take effect; not an easy task for storms that arrive in the night. And worse, while sedated, dogs can be very unstable on their legs and become a danger to themselves. Dosi would try to jump off the bed and risked breaking a leg, and she would remain groggy and unstable for a long time after the storms had past. So after a couple of uses, the sedatives were set aside.

But then they heard about an alternative approach to relieving noise anxiety...the unique approach now offered by ThunderShirt. It was amazing. With the very first usage, within two minutes, Dosi’s shakes had practically disappeared, and she lay down. And ThunderShirt's gentle pressure relieves many other anxieties too.

ThunderWorks Gives Back!
Anxiety is a serious problem for millions of dogs. And dogs that have been rescued by one of the thousands of terrific rescue groups across the country, or turned into one of the thousands of animal shelters have a much higher rate of anxiety issues. Many dogs are turned in or abandoned BECAUSE they suffer from anxiety...their anxiety symptoms can be very destructive or hard to manage for many dog owners if they don’t have the resources or knowledge to help their suffering pets. ThunderWorks is donating ThunderShirts and thousands of dollars to help these organizations manage their dogs' anxieties and find them good homes.
