Promising review: "Mystro is a 15 lb, 9-year-old Maltese Schnauzer mix that is terrified of any loud noises, shouting matches, fireworks, thunder, and small children. He has a popular Storm Shirt that I use with these drops or without as indicated by the pictures. He likes to sleep. Do not be alarmed and think that these drops drug your little furry partner in crime, as they do not (I have more pictures of him sleeping, he just likes to sleep) — they produce a calm dog, without all of the storm anxiety. These drops are heaven as he does not tremble, pant or nervously follow me from room to room, trying to hide, it is as if there is no thunder, shouting, small children, etc., he is his normal laid-back self." — Petitesi020
