Thanks so much guys!!!
I was thinking semi quarter to begin with but I wanted to double check.....ive always had standard bred horses so the whole owning a horse thing is still somewhat new. I've always ridden but never my own horses so I don't know much about saddles.
I know how to measure the gullet and all that but not the horse...
So, now that I know how to, im going to do my best!!
So thanks a bunch guys!!!
