Is Sentinel Senior a good choice for a senior horse with Cushing’s and insulin resistance, or would it be better to try a forage only diet like hay or hay pellets?By NS KNG Admin / March 25, 2024 Every horse is different, and sometimes the best choice may, unfortunately, require trial and error. Sentinel Senior is a great choice, and we’d recommend it in this situation. There are varying degrees of Cushing’s and insulin resistance, and these conditions can change over time. If your horse is doing well, stick with this program. If you see changes or the condition progresses, different nutritional approaches can be considered. (Kristyn Sturken)
