Bite taken out of Olympian's case as positive from dog meds

Nowhere in the complex labyrinth of rules, bylaws and interpretations that govern the global anti-doping system did anyone see this warning: Beware of Dog Medicine.

It's an understandable omission, but one that led to a three-month sleuthing expedition that eventually exonerated a five-time Olympian of doping while adding what some feel is an unnecessary asterisk next to her spotless record as a clean athlete.

Katerina Nash, a mountain biker and cross-country skier who represented the Czech Republic in two Winter and three Summer Olympics, avoided a four-year doping sanction after minute traces of a banned substance showed up in her system. Authorities determined the substance got there through her skin during the messy struggles she faced in forcing medicine drops down the throat of her ailing dog, a Vizsla named Rubi.

Despite not receiving a sanction, Nash's encounter with anti-doping authorities still went on the books Thursday, a byproduct of long-enshrined rules that call for any doping violation, even an inadvertent '«adverse analytical finding» such as this one, to be announced publicly.

I would not have cared for my dog in any different way. But in the end, I was touching this medicine every day for about three straight weeks.»

Nash lives in California and was tested by authorities from the U.S. Anti-Doping Agency. The results that showed up several days later at USADA offices raised eyebrows. A trace amount (0.07 billionths of a gram per milliliter) of a substance called capromorelin had shown up in Nash's urine. Though
