I started giving the biscuits to my 4 year old shih-tzu who is terrified of thunder and fireworks. Prior to using the Canna-Pet I would need to use a thunder shirt and an essential calming oil. Over the July 4th weekend – I started giving her the Canna-Pet biscuits twice a day and she was relaxed and calm during all the fireworks activities. This has been a godsend for us — during thunderstorms she would wake me in the dead of night in a panic. Now if a storm is predicted, we give her a biscuit and the storms do not affect her. It has definitely given my shih tzu relief during all these recent storms.
