I read some previous emails and she said he's sound, not spooky, and has never been lame.
Sorry but I have seen this video before elsewhere and it was determined he was unsound. I remember the huge, huge, huge problem with the front leg swinging way, way out. It was more than winging/paddling as it comes from much farther up the leg.
This horse as he stands is worth about $50.00 and is auction material.
