(Lightning) my 10 year old palomino seems to have gained a lot of weight since I bought him 7 months ago. He looked really good when I first got him and he had not been ridden in 3-4 years. Now he seems to be getting fatter everyday. I ride him about 4-5 times a week in the arena for maybe 40 mins walking, trotting, cantering etc. He grazes on 6-7 acre pasture whenever I'm not doing something with him but I don't really have anywhere else to keep him. Today I really worked him hard galloping through my fields, cantering up hills, trotting and loping circles etc. The first and third pictures are him now. The second and forth are when I first got him.
