I recently purchased a 13.2 pony at auction. He had a saddle on all day so he looked bigger there. We taped his weight at 779lbs but he could gain a few more. I’m 140-145lbs and 5’4”. I’m looking into getting a synthetic saddle that’s 15-20lbs at most. Do you think it’s unethical for me to ride him? I love him and would hate to sell him now that we’ve bonded but don’t want to hurt him either.
