Yes I remember Barbaro. I felt so bad for the horse though because he was in top condition healthwise and one mistep broke his leg which kept getting infected further complicating things and eventually the Vets in charge of his care spoke with the owners, trainers, and riders, and they all came to the decision to euthanize Barbaro.
I almost cried when I heard the news that Barbaro had been put down. It would make a good movie similar to 'Sea Biscuit'.
I have a good friend of mine who is a Vet Student at LSU and this is the very thing she is interested in, Equine Medicine.
