Gray Arabs all start off some sort of chestnut or
bay. Some don't change until late in life. Others are like
camillians. Most are snow white by their teens. Horses not out in
pasture don't have the color fading from the sun and sweating. Some
become dappled when have a higher fat diet. Just the way it
is. It is not anything you are doing wrong. Some never
loose their fleabitten. Enjoy. Mary Ann
