The Belgian doping case at the Paris Olympics
Isn't that just the absolute weirdest thing that ever came to light? Not that the horse ended up on the positive side of a doping test. But more the after math of this bizarre story.
Some of the key players in this twisted case are; the rider, the doped up horse and the team vet.
According to the third paragraph in Article 118 in the FEI General regulations for competition the PR - person responsible - for a horse is the athlete. Others can be included into this, but the main person responsible for the horse is the rider.
