At our last horse show I seen a young girl stick a syringe in her horses mouth. I got a look at the bottle and it appears to be a calming agent. I don't think calming agents are legal to use in the show ring. I could be wrong.
Cinny the horse was on Smartcalm but 3 months before showtime we stopped giving it to him.
Go ask whoever is in the show office. I know buting for our area is not legal unless you actally go ahead of time and TELL them you are buting and WHY you are doing it. They will then decide if it is legal. I do not believe calming agent is illegal but I could be wrong.
You can't report someone for something you believe, or think , or coulda , maybe mighta been, but yes if You KNOW it is against the rules, an you KNOW you saw it, and YOU know 100 percent without a doubt what happened and know the applicable rules you should report it. Hover that doesnt seem to be the case here.
It wouldnt matter to me if it was a local show or the Olympics. The published rules are the published rules. But you need to know what those rules are, and know 100 percent that the rule was broken. Remember, all that is needed for evil to triumph is for good men to do nothing.
