Excellent, Zylkene have helped our dogs and friends dogs
Our vet prescribed Zylkene for our rescue Golden Retriever, Fireworks, thunder, shotguns terrified her, and she would dig wherever she was, corner of a room, our touring caravan, friends garden,she was a shivering wreck. Zylkene changed her into a happy girl, without zonking her out, or upsetting her tummy. I've given Zylkene to a friends rescue Border Collie when caravanning because of thunder and shotguns, she too became calmer. I am now never without Zylkene in our dog first aid kit.
