What Adoption Agencies are Saying

Already helping thousands of adopted dogs across the country, below are few comments from shelters and rescue groups.

“Thundershirt has been a very useful tool for both staff and shelter dogs. We’ve also seen great results through our retail store.”

~ Denise Gurss, Director of Animal Welfare, Nebraska Humane Society

“At Paws4Ever, the generous donations from Thundershirt Company have allowed us to use Thundershirts on dogs in our shelter who encounter large amounts of stress in everyday life. Thundershirts are easy to fit, easy for owners to use, and usually start working right away. We are proud to sell and recommend this product!”

~ Julie Jenkins, Dog Training Manager, Paws4Ever, Mebane, NC

“At the Best Friends Animal Sanctuary, we frequently use Thundershirt with dogs who show a lot of general anxiety, and dogs who lack confidence. The Thundershirt can help ease their adjustment stress in the short-term. Thundershirt can also help with general anxiety over a longer period of time. The Thundershirt is so wonderful for our Sanctuary dogs, as it is lightweight, easy to put on and stays in place.”

~ Jen Severud, CPDT-KA, Best Friends Animal Sanctuary, Kanab, UT
