I remember doing a show years ago, and there was a girl with this Arabian, and while everyone else was working their own horse, tacking up, grooming etc., she had her, I'm assuming trainer, do the tacking up and the lunging. She got on the horse to do the classes, then promptly handed horse back to trainer. Now this was a 4-h FFA show, big year end show, but no one else had a personal trainer like that. She placed in the top 3 in every class that she did, but I agree with Breela.
we had a girl like that...really ended up sucking for her when she got to county fair and the rules stating that you "CANNOT have a trainer ride your horse at the show".
She lost her first class of the day to me (English eq.) so she stormed out of the arena, threw the reins at her trainer and let the trainer get on and discipline the horse...then she got DQ'ed because the judge saw her trainer on the horse!
Believe me I know it seems unfair to have girls like that and cheaters in general...but what counts isnt the ribbon, its the notice you get for being a good fair competitor, and for putting in the hard work to get your horse that way....
Who do you think people will go to down the line? The girl who cheats/doesnt train or ride their own, or the girl who put in the hard hours and spent the time with their horse. And then went out and beat the cheater fair and squaree? Don't sweat it...believe me the right people will take notice of you.
