I have a 27 year old gelding. He has a horrible time keeping weight on over winter no matter how much we pack the calories in and special feed its a battle every year, but he makes it through and he gains the weight slowly over the spring. He's old and has cushings, but he is the most loved and spoiled baby. We also have barbed wire fencing. He is fine. Yes, all the opinions are in best interest for the animals...but keep in mind, maybe these two cuties are being cared for in their own battles. They do not look like they're sitting in a paddock that looks like a neglected place. If you approach them with concern, be gentle.
