She looks Paint to me. The size of her, body type, high stockings, belly spot, white face and white along side her jaw. She might have Quarter horse in her, but actually if you breed a paint and quarter horse together, it's considered a regular paint if it has color, breeding stock if no color (can sometimes be double registered AQHA and APHA). Which she does...It's minimal, but it's there.
