Help me! I've been starting to ride a welsh pony named "Dolly" (i call her a demented shrimp) for a lady. Dolly doesn't get any attention, and she's never had her "own" human. She was only ridden by little kids, so she got away with a lot of really bad manners. She's really, really barn sour and throws hissy fits when you try to ride her away from the barn. I'm an experienced rider, but I haven't worked much with barn sour horses. I tried everything I could, so i'm really frustrated that I can't do it. Please help!
