Rose-Hip Vital has made a huge difference in my Mammoth donkey’s mobility. Sierra is 28 and has had a noticeably smoother gait and increased activity. It is awesome and she welcomes grain time and waits at the barn door for her Rose-Hip Vital, it is also excellent to put atop the lesser preferred meds when needed. Thanks Rose-Hip Vital for improving my sweet senior’s quality of life, she loves your product and she’s worth it !!!
