ACV for Horse Sore Backs
(Akron, Ohio, USA)
I had a horse that through its back out at the county fair one year.
I couldn't ride him and still had to show.
My farrier had suggested mixing ACV, water, salt, and absorbine into a spray bottle and rub it in to his back.
It worked over night. Pride was fine the next day, we even got two first's.
