Okay so I was wondering about my gelding he's much wider in the chest and rump then the geldings I've seen. He's always muscular no matter if I work him or not. Bu twhen I worked with him he always gained more. He had wide cheeks and has a REALLY nice thick long tail (idk if that helps). His leg muscules are twice to three times bigger then my other geldings. He's also 13 years old. He's about 16hh. Could he have been gelded late? Or is there another reason he's so big?
