Pet Supply Outlet is proud to carry Thundershirt in Belmont, Massachusetts. We are incredibly proud of our innovations! We are not about innovating for innovations sake. We are making affordable, effective, easy-to-use solutions for real problems faced by real pet families. We don’t want to be offering the same old products offered by literally hundreds of companies – just another dog bowl, just another leash, just another dog bed in a different color or material. We strive to achieve innovations that create functional, real solutions for common pet problems. We are incredibly proud of our Calming and Walking innovations.
