I disagree. We had a premature Arabian Gelding who was abused for a couple years. When we got him, we trained him and tried to put weight on him but he just wouldn't keep it. We had he teeth done, a few pulled, every year, once or twice. He received one scoop of grain, and 1/2 a bale everyday. He almost always had access to a round bale. We didn't ride him a lot, and you could still see every bone in his body.
We also had two off-track thoroughbred mares. One, who is 24, and my dad's baby who is 12. The eldest, Wings, was terrible to put weight on. We rode her a few easy times every month, and for one week at the county fair. She had 1/2 bale every day, and in the summer she got a scoop of grain. Almost always she had access to a round bale. Even now, at a retirement home, where she hasn't seen a saddle in 8months, still is a skinny horse. My dad's horse, Chicky, is ridden a few times every week. She gets beet pulp 2 times a day, full access to a round bale, 2 scoops of grain, and another 1/2 a bale. Her teeth are fine, she's healthy. And guess what? She's still underweight. We have tried to get all 3 of these horses to a normal weight for 7 to 8 years now.
Now you tell me that we didn't try and spend a ton of money to keep our healthy horses fat.
