Oaklawn to give bonuses for winning without Lasix

[saratogadew]

Are horses tested before or after a race? I know they are tested for illegal medications. And is this testing done just randomly, or are all tested? Also, Lasix is a legal medication so why would horses be tested for that? In the PP's, when it says that a horse is running with Lasix, is this just the trainer telling someone in charge? sorry for all the questions, this area of horse racing has always been a little fuzzy to me.
