Safe, Simple Calming Solution
ThunderShirt helps reduce anxiety

Problem Solved

ThunderShirt helps reduce anxiety caused by loud noises like fireworks or—as the name implies—thunder. But that's not all. This versatile solution can help dogs with separation and crate anxiety, and those who get nervous during car or air travel, vet or grooming visits, or when guests visit the house. It can even curb unwanted behaviors like leash pulling, barking, digging and scratching.

Size 'Em Up

ThunderShirt is designed to be easy to put on and easy to adjust for proper fit, even if your dog is already in a state of anxiety. So it only takes a few seconds to make him feel more safe and secure. Be sure to pick the right size for your pup for best results.

About ThunderWorks

ThunderWorks was founded by a doggy daddy whose panicky pup couldn't stand thunderstorms or fireworks. When all the vet had to offer were risky medications, Founder Phil Blizzard fashioned a people shirt to wrap around his dog, and ThunderShirt was born. Today, ThunderWorks is dedicated to providing simple, effective solutions with a range of products designed for the most common pet problems.
