11 year Shih Tzu here, a total fun-police and bossy babe.
I have been giving it to her for her fear of thunder (not so tough here) we live in south Florida and at during summer it rains everyday 10 times....works wonders. Just in the past few months I started giving it her overnight before bedtime and I have noticed a huge difference on her sleep, her energy levels have increased and I think it has helped with her allergies as well, she is not so itchy anymore. I highly recommend this product A+...
