    They seem to be working!

    The dogs both love the taste of the supplements and they do seem calmer after having them for about 6 weeks. They are definitely less reactive when on a walk and seem much calmer and relaxed in the house.

    Stress and Anxiety Supplement

    My dog has been enjoying these supplements for a few months. To be honest, at tge start of the treatment I could not identify any change in my dog, however after a month I started to notice my dog becoming calmer and less anxious. I think it’s like a lot of things, it takes time to build up to show it true potential.

    I would say they are working well. The big negative with them is the price. In comparison with similar products, there is a big difference in price but similar ingredients.

    I will stick with them for now but I may have to opt for a similar product at a cheaper price.
