My trainer measured my horse's back to satisfy her own curiosity. She'd been talking to a couple of friends of her who are vets about my horse being short-backed. They had said the shortest mature back they'd measured had been 23" and her own horses don't measure shorter than 24".
My horse? A whopping 22" and just barely at the 22" mark. Lol! All I could do is shake my head and laugh to myself. *sigh*
Definitely explains why I've had such a difficult time finding saddles and saddle pads for him!
