A couple of clarifications re: Pony Finals.
Eliazabeth Mandarino, a professional, was administering Mag Sulfate to a pony, Humble, at the Devon Horse Show in 2012 and the pony died as a result. Not Pony Finals, not that it makes it any less heinous.
Calling her a “pony mom” is a little more disingenous. She has a well known barn with a big program; the pony Humble was leased to one of her clients, but was under her care, custody and control. She did also have a daughter who was a pony rider at that time, I think (?), but she was acting in her capacity as a trainer and owner of the leased pony when she gave the injection, not a “pony mom.”
The fall out from the incident was immediate and intense. There were investigations and a lot of attention was focused on excessive med regimens in the top hunter barns, and performance altering substances that don’t test, like Carolina Gold, GABA, Perfect Prep and mag sulfate.
So, as someone else has said earlier, any time you have horses and people and then add competition, you have the potential for abuse. All horse sports have abuse; the best only have it on the fringes or among a very small percentage of participants.
But the Mandarino/Humble incident is a very, very poor comparison to the issue in Modern Pentathlon. The primary issue being discussed is the EPIC poor sportsmanship/poor horsemanship displayed by the German rider. A better comparison would be the hunter rider (A J &J heiress, IIRC) that was sanctioned for kicking her horse in the belly in a fit of pique after she fell off.
The secondary issue is that the current rules of Modern Pentathlon create a situation that is rife with horse welfare issues, and some posters were making reasonable suggestions for changing the rules to make it safer for the horses.
Playing “But what about abuse in other horse sports?” is a weird flex and not particularly relevant to either issue, ie, poor horsemanship or changes to the rules to ensure horse welfare.
