Thank you for your replies.
Yes, I do have irrefutable proof. I watched the entire scenario, from walking through the ingate to dismount. I heard the parent talking to the trainer. I talked to the rider. The fact that NO ONE - rider, parent, trainer, other riders sharing the ring - so much as blinked an eye, asked a question, or looked taken aback when the trainer walked into the middle of the ring and injected the horse in a neck vein is beyond comprehension to me.
The fact that some of you who responded seem to rationalize this practice is beyond comprehension.
I’m not painting an entire sport with a broad brush. But what am I supposed to do when I see something like this, learn about USEF sanctions, and then discover that another trainer in my area has been fined and suspended for exhibiting a horse that tested positive for sedatives at an A show? Maybe it is the Zone that I am in. I don’t know.
I certainly won’t give up riding. I truly care about my horses and look forward to riding and spending time with them every day. But, I will not horse show and I will not continue to ride at this facility.
My experience with the pro peloton has left me with a non-negotiable stance about this issue. The situation reminds me of what Betsy Andreu went through when she told the truth about the drug use in pro cycling. The inner circle rationalized, explained, and obfuscated. She was criticized and vilified. But she stuck to her story because she was telling the truth.
What makes me sad in this situation is this: The cyclists always had a choice. Even when they said they were pressured into doping, there was always that moment when THEY made the choice. Horses that are drugged do not have that choice.
As in cycling, using drugs to take shortcuts, gain a competitive advantage, and hide weaknesses in training is wrong. Period. The End.
For those of you who show and do not sedate your horses, I commend you. It must be difficult to know that your competitors may have a pharmacologic advantage. For those of you who think that sedation and tranquilizing a horse under saddle is acceptable, I think you are so inured to what is wrong with this this practice that you can no longer see what is ethical and right.
Good luck to you all.
