I've never heard that apple cider vinegar will hurt a hypp horse or anyhorse for that matter. A lot of cattle ranchers i know have used it on all the horses and it was fine.
But i love the stuff and u can get so much of it for so cheap!
Jubilee Rose its not plain vinegar in a bottle it's called apple cider vinegar, its in the same isle as plain vinegar but it's kind of red colored, but dont get mixed up with red wine vinegar, theyre two completely different things
