Horsies and Feetsies

Last Friday, there was a prescient article about the breeding of horses for racing in the Wall Street Journal:

Like hemophilia in the Russian royal family, Native Dancer's line has a tragic flaw. Thanks in part to heavily muscled legs and a violent, herky-jerky running style, Native Dancer and his descendants have had trouble with their feet. Injuries have cut short the careers of several of his most famous kin, most notably Barbaro, a great-great-great-grandson who was injured during the Preakness Stakes and was later put to death.

I haven't seen the article (or its timely publishing) mentioned anywhere else, so I thought I would.
