Currently my horse doesn't look very pretty. He'll be moving to a new barn, so I'm sure that will improve his looks by not getting so beaten up. I got him in April, so it's a guessing game to know what he needs or what will help. He's an 18 yr old QH. Could use some fat. And healed ouchies show through the thicker coat he's getting. Since I got him, he's just been on sweet feed for grain. Because of work I haven't been able to ride him often, so I would think he should be some what fattened up. What can I add to his grain? Our 30 yr old horse Joe which is boarded at a different barn is fed Dynasty Senior with his grain and he looks Good! Wondering if adding the same to Spike's diet would be a good choice or if I should try something else?
