We have a six month old Lab mix rescue that is super hyper. After breaking the growth plate in his leg, we went through hell after the surgery trying to keep him calm. Even the vets tranquilizers were useless. After many internet searches I found Composure and decided to try it even though it is awfully expensive. I used 1/4 teaspoon mixed with a little of his favorite canned food and all I can say is it is a miracle worker!! It keeps this pup calm yet not drugged. More like a calm , older dog acts. I will never be without this natural formula again!
