I just read the article on Eight Belles's death. Here it is if you're interested. http://www.nytimes.com/2008/05/04/sports/othersports/04rhoden.html?&no_interstitial For anyone who's knowledgeable with horses, why does an injury to a horse's leg force them to be euthanized? I know Belles's case was particularly severe, but sometimes seemingly minor injuries lead to euthanasia as well.... I heard that it was because there isn't much blood that gets circulated down there and it's practically impossible to heal. I'm not sure though.
