This is my boy Charlie, he is a 20 year old standardbred trotter, I have had him for about 5 years, I had not ridden for 18 years he wasn't the easiest ride as being a trotter, but he really does try. I put Charlie on simple system just about a year ago and and his condition and temperament has changed so much, everybody always comments to how well he looks, and he certainly doesn't act like a 20year old 😊
