I follow a few EU breeders/young horse producers on Instagram. They’ve been really interesting to watch how they take youngsters to their first shows - usually they haul in for a day with a friend and just hang out. Then haul in and canter around the warmup. Then haul in and do a few jumper classes where the focus is entirely on giving the horse a good experience, NOT ribbons or anything competitive. All for just a day.
The advantage of this model is a young horse going to his first show isn’t expected to live on the busy show grounds for a week or more and lope perfectly around multiple hunter divisions. They go for a DAY, and pop around jumps they’ve probably seen before (arena hires are more common), and are expected to be a bit squirrelly. Then they go home to their pasture and friends and think about their experience.
A good US hunter trainer (or trainer in general) will give similar experiences to their youngsters - it’s just harder here. Bringing up a baby from scratch is tough if you’re living on the circuit and/or staying at shows T-S. (That’s part of the draw of imports I think - the well produced ones have had that homework done already). Clients are expecting RESULTS - after all, they’ve been waiting for ages and the show is costing them $5K or more… unless the trainer has installed concrete expectations, it can be tempting to reach for a non-testing chemical might-help solution (or lunge for hours, or tell the client to sell and buy something made) instead of doing the homework.
This got away from me a bit. But I think, as always, there’s “exposure to shows in a way that benefits the horse” and there’s “exposure to shows but done unfairly”. Good trainers do the former, poor and/or uneducated trainers do the latter. You’ll see the range at any given show - but I have to say I’ve seen the worst at unrated competitions. The unscrupulous people at USEF shows tend to hide it better, I guess. Or get booted
