CHRB HITS O’NEILL WITH FOURTH TCO2 COMPLAINT

The California Horse Racing Board has filed a complaint against trainer Doug O'Neill for an alleged total carbon dioxide (TCO2) violation—the fourth time since 2006 a horse in his care tested above the threshold level for what is commonly called “milkshaking.” The latest allegation involves Argenta, who finished eighth in the sixth race at Del Mar on Aug. 25. The CHRB complaint did not specify the level at which Argenta tested, only that the daughter of Mineshaft exceeded the regulatory threshold of 37.00mml/l for TCO2.


O'Neill, Del Mar's leading trainer, earlier this summer served a suspension for a TCO2 violation in Illinois. He was also hit with sanctions in 2006 and 2008 for failed milkshake tests. He told Daily Racing Form: “To the best of my knowledge, no substance was given to this horse that would have raised her TCO2 level. Consequently, I'm working with CHRB investigators, trying to figure out what happened.”


Argenta is owned by W.C. Racing, Westside Rentals, and Neil Haymes.
