Only had this for just over an hour. And my dog has gone from a shaking wreck (she literally sits and shakes all day long) to calm and playful. Tried lots of different things but none have worked except this. Haven’t tried walking her yet but happy with how it’s helping in the house. Started working in about 30mins. Two spays on bandana. Hoping it will help with fireworks and walking her as she is terrified of the outside world, loud noises, children, men, big dogs, fast moving objects, balloons, anything loud that’s moves that’s big lol and she’s only small so most things are bigger than her. Serene um calm she’s been on for a week and no improvement. So very happy with this.
