She looks like a nice horse, but needs more training. But she is only 3. I do like that she doesn't care about buckets being dragged behind her, or in front of her face.
I don't like that she's in foal, but that wasn't your fault. But that fact alone would turn me off and keep looking for another horse. I don't know what her price would be. Around my area, i'd say between $1,500-2,000, maybe more as her training progresses.
Do you know what kind of horse she's bred to?
