Helping solve the problem of dogs pulling on a leash was a natural choice when the team at ThunderShirt was looking for a line extension of the ThunderShirt brand...and we were excited to work on yet another awesome spot with our friends at ThunderShirt. Once again we found user testimonials paired with happy dogs to be a powerful one-two combination that really makes the phones ring. We know that there will be more happy dog walks in America thanks to the ThunderLeash!
