Okay, so this is my 2006 Quarter Horse mare, Hancocks Go Maggie. She is obviously a dappled Palomino. But there are a lot of dark brown spots on her, and I have no idea what they are or what they're called. I've had her since she was a yearling, and she didn't have them then, but Maggie has never had much for bites, and none of these are scars or sores. So does anybody know what this coloring would be?
