Im large,I aint going to lie. My horse how ever doesn't have much of a problem carring me. WHen I ge on there is no movement for flexing in his back. I don't know what to look for though.I kinda wish I did spot something that led me to think im to big for him cause that would probably be just enough for me to finally go ahead and stick with a diet.
He tripped with me the other day and really had no issues correcting himself but he is a refined horse and he just dosnt look like he can carry someone my size. But then again my mother at 200lbs used to warm up my shetland for me when I was a kid.SO is it just a case by case thing or is there a set standard
