I did not think these would work, because I have tried other calming treats like Vetriscience without luck. But I give my dogs Bocces Bakery chews, joint supplement, and probiotic supplement so I decided to try them. One of my Shih Tzu is very high strung and these help her to relax. I also give them to my other 3 dogs when there is a stressful situation like thunder storms or repairs being done in our house. Works really great! Just makes them calmer and slightly sleepy.
I think they are helping her calm down a bit. She's pretty hyper so it's hard to tell sometimes
