Why does drug testing only occur on the last day of a multi day show? The halter horses are gone, the english horses are gone and the rest of us are trying to get finished and leave. Horses frequently have to be hauled multiple hours to get home in hot weather. If your horse doesn't pee the testers want to administer something to make them pee. Thus the horse is stressed and possibly low on hydration going home. Drug test in the middle of the show. It will be much more random as it will potentially affect all class categories. The randomness only seems to affect amateurs and novices not the open horses. Statistically, it seems unlikely that this always occurs. If AQHA really wants to reduce abuse, they should apply the drug testing in an even handed fashion.
