    Highly recommended!

    The stuff really works, but you do have to give it a little bit of time and then be consistent in the dosage.

    It has helped one of my Romanian rescue dogs who is very nervous, the other one doesn't seem to tolerate it and has been sick after I've given it to her!

    Bought your two for one special then ended up paying duty to get it shipped to me. Have used this product for 3 years. My dog is still dog reactive but is a wonderful pet. Am afraid to stop it.
