I have to say,,, you made me laugh. Not at the offensive question, but at the ignorant way you went about it. I am not a heavy person but have friends who are and you know what,,,these horses are fine with any weight you put on them. I have a larger pony maybe a little bigger than a shetland and I feel huge on her. She doesnt seem the least bit hindered by my size. She carries me with no problems and rides like a dumptruck. Just tough.
