Promising review: "I rarely write reviews, but felt compelled to do so after seeing how effective this shirt has been on our dog. We have a 30-pound rescue who's about 6 years old. She's the sweetest girl, and very 'dog-like' with my husband and I. However, whenever there's company (regardless of how many times she's met them before), she freezes up, gets tense, and hides out in a comfortable area. Long story short, we thought we'd give the Thundershirt a try. I really didn't have any expectations considering her level of anxiety. We brought her to my aunt's house for Christmas where there were 17 people (many of which were kids under 9). She was a new dog. She was walking up to people, letting them pet her, and tail up the entire time. Everyone was commenting on how social she was, and how tolerant she was of the five kids who were completely smothering her with love! I will be using this for all future social gatherings. I don't want my dog feeling anxiety, and this shirt clearly brought her significant comfort." —laurenmickelsen
