We have been told by various trainers and judges to buff the hooves and spray with the clear enhancer made by Ultra on white hooves, black hooves get buffed and use black Ultra polish.
Alot of black hoof polish that is out there is harmful to the hooves unless you take if off after a show. We try to use the boot cream also, which is a great help. Everyone has their own opinion on this subject. We also paint the stripe in the hooves if there is one.
And as far as the showing of appaloosa's and painting their hooves black, well...we were told by a ASPC/AMHR judge at a Area I show that we didn't place well because of the hooves not being clear so to see the stripes, we didn't know that back then either, so its better if you are showing appy's to clear them, which we only have Diva left that is our own bred appaloosa that we are retaining ..all our other appaloosa's will be gone in a few months to their new owners.
Most judges will agree, white hooves, no black polish. Something else that they all look at in the ring ....is if the hoof is trimmed properly, nothing rough looking and all 4 hooves are at the same length and look as the same as possible as far as shape. Everything is a factor and you want your horse to look as perfect as you can no matter how silly it may seem.
We were fortunate to had been selected to be awarded with the "Inagural Vetrolin Grooming Award" for the "Best Groomed Shetland Pony" at the National Shetland Congress in 2007 by Farnam Horse Products and the Platform Feed division out of 500 horses, so we must have been doing something right. We had recieved the entire line of their grooming products, multiple coupons for the Platform feed and many press releases that the Director of Marketing of the ASPC/AMHR had sent out to various equine magazines and newspapers, plus was on the airing on RFD-TV with our award and shown with our miniatures at the very beginning with our Park Harness horse......it was quite a surprise that I will never forget.....
