I'm not sure how true that really is. Because it
has been known to be an urban myth in the past.
As for racehorses (any horse, for that matter), blueheaven [okay ESPN guys] is right. The simple fact is that even when horses sleep, they remain standing. Even though a horse will sometimes lay down, the majority of it's life is on the hoof. This is because of their wild past, as a prey species and their only defense is run or kick. (Why do cows lay down more? I dunno.)
In fact, even if an attempt was made to save this latest tragedy, G.W. horse would have been eventually euthanized, just like Barbaro was.
The trainer did have the horse's best interest in mind. It would have suffered too much had any recovery be attempted.
Unfortunately, there are
MANY more little or no-name racehorses that break-down on the track every year and are immediately euthanized. We don't hear about them because the races aren't 'that important' to the public. However, the televised races(The Derby, Preak, Breeder's Cup)- those horses- are like the horse equivalent of the human celebrity. It's a big deal when one of them breaks down.
In fact, there was a tragic race in
last year's Breeder's Cup roster. One horse was euthanized and another had to end it's racing career-- in the same race. (Breeder's Cup has a card of seven races, not one.) I guess not many people remember that because of Barbaro.
Irony dep't.: George Washington (racehorse) came from the same breeders as Barbaro had.
