We are amazed by the results we’ve seen from giving our dog, Woody, Leap Years! We are in our second month and we see tremendous improvement in his mobility and demeanor. He has had a spinal stroke, which left him with weakness in his spine and back legs. We didn’t expect to see the incredible changes that we have experienced in his mobility! He gets up easier and walks with less effort, plus an added bonus of being happier and almost playful! Leap Years is a miracle and we are so thankful to have found this product! It has brought new hope and health to our sweet, older German Shepherd, so that he can enjoy his later years of life! Thank you so much!!
