Just bought this horse!
Yes, I am dragging out this ancient thread because I just purchased this horse last week.
I found him local, owned by a gentleman who had him sitting in his yard. "Charlie" as he was called, was very underweight. He's been slowly putting on weight, and is doing well. He seems to have gained some considerable energy.
He DOES appear to have something weird going on in a front leg, but I've not had an exam done on him yet (he was too weak to trot in a flex test, and I didn't want to just order an x-ray $$$$$). Whatever it is, it's not noticeable from the outside... for all I know it could be his feet, which are shoe-less and thin-soled. He seems to be okay some of the time, and then a little ouchie at other times. I'll have him checked out within the next couple of weeks.
It's unfortunate that I can't watch the video :(
