Raceday Lasix is one of the more controversial issues in American horseracing. The critics say that the drug is but a performance-enhancer: A diuretic, Lasix helps shed water weight prior to a race – lighter equals faster – and as a system flush may also aid in concealing some of the illegal stuff. Supporters, on the other hand, call Lasix “humane”: Rapidly moving racehorses, they say, naturally bleed – from their lungs – “exercise-induced pulmonary hemorrhage.” Prominent trainer Dale Romans (Paulick Report, 9/13/12): “Racing causes [EIPH] in 100% of horses. …one of the worst abuses that can be done to the racing horse is to ban Lasix.” Adds colleague Rick Violette (DRF, 8/11/11): “Horses bleed. That is a fact. To force an animal to race without [Lasix] is premeditated, borderline animal abuse.”
That raceday Lasix – by the way, a uniquely North American thing – is primarily used to make horses faster is a pretty good bet. (While not all trainers particularly like it, practically all, so as not to cede any competitive ground, use it.) But what if the Romans/Violette crowd is also correct – that pulmonary bleeding is inherent in a racing-horse? Translated, this would mean that the “sport’s” fundamental physical action universally causes some level of pain or suffering. Of what other basic sporting motion can this be said? Throwing a baseball? Swinging a golf club? Kicking a soccer ball? If not for the deadly seriousness of it all, these people would be laughable.
