This is a Northlands horse. I see lots of fatties riding them because they are known for being strong and sturdy and can carry a bit more than other breeds...which doesn't mean that they can/should carry 50% of their weight though. Mine is 400 kg (880 lbs, the weight of a bedbound deathfat), I weigh 57 (125 lbs), he could carry more but I don't think he would appreciate it.
