HOw do you know if they are this or not? I have a yearling filly here that I bought as a foal. She was born a palomino pinto, and you could see her spots as a foal. Now this year as a yearling she is all white and you can only see her spots when she is clipped down(with a 10) and wet. You cant even see them when she is just clipped. Could she be a maximum expression sabino?
