Thundershirt's gentle, constant pressure to your dog's torso has a dramatic calming effect for most dogs if they are anxious, fearful or over-excited. Data collected from surveys completed by over two thousand customers reveals that over 80% of dogs show significant improvement in symptoms when using Thundershirt. As for WHY Thundershirt's gentle pressure works to calm a dog, experts such as Dr. Temple Grandin believe that pressure has a calming effect on the nervous system. Thousands of veterinarians and dog trainers now recommend Thundershirts for their anxiety cases. For many anxieties, we recommend just putting on a Thundershirt and observing the results.
