She looks, walks, trots, and canters totally sound looking in her videos. She was a 13 year old boy's horse until he lots interest in horses for sports, and they've had her since she was a weanling. They broke her, gave her to their kid, and now are selling her because he lost interest.
Well, I called the vet back and they can't even do exams on Saturdays. This horse will be sold Saturday even if it is not to me--the owner promised me first dibs, and I get to see her first, but three more people are coming after me if I don't buy her then.
But I honestly think she is fine. This is in a really country, quiet, everyone-has-horses kind of town. She has e-mailed me probably over 100 times at this point, and she seems honest, sincere, and claimed she has bought horses mistakenly and would never do that to someone else.
