Too chubby or just right? And do I really see some improvement in his muscling? He's currently 24/7 in a grass pasture and gets 1kg of oats, split into two feedings, daily. Please note that he's a carriage/light draft type horse and is not supposed to be TB-style lean. Also, he's not THAT bum high - I was alone at the barn when taking both of these pictures and just couldn't manage to square him better. Thanks for your input!
