When he rode my horse (who is a 15.3 hh very lean/slightly underweight QH/Arab/TB hothead), the horse seemed to cave under his weight (he rode with the saddle). And I lowered the stirrups all the way and his legs still looked to be in a jockey position.
I guess my questions are
1.) do you think this draft/appy cross (she is very stocky) can handle his weight AND a saddle?
2.) How do I find a draft horse saddle with very long stirrups???
