I show a kicker, she's never made contact with another person/horse since I've been to the barn (be it me or someone else riding her), and I don't plan on not showing her because of this.
I, truthfully, wouldn't take a horse off the show circuit (be it schooling, states, nationals, etc) just because it kicks. Showing a horse is both the rider of the horse and other riders' responsibility. I'm not saying that it's fine to just let your horse run around kicking at everyone and trying to say that it's their fault, but both you and others, as riders, need to be aware of their surroundings and what they're riding. I do compare it to driving, because even if you're the best driver there is, there's someone out there that isn't and they may come into contact with you and your vehicle, literally.
Now, as for the actual OP. I would tie a ribbon (not a small piece of yarn, either a thick shoe-string or an actual ribbon), or anything red that is blatantly noticeable in his/her tail, and also make sure that if you feel anyone is too close to tell them that your horse is a kicker. I ride by fair warning, I'll tell you I have a kicker 3 times (and make it obvious and not say it nicely after the first time), and then it's your own stupidity if you get kicked. And if you're riding up my butt, even if my horse decides to kick or not, I will stop and about take your head off until you -clearly- understand to stay off my butt. I'm not the nicest or most patient rider at our shows, but I will be truthful and give fair warning for anything, including kicking.
Yeah, it's best to work with the horse at home, but in my case, it's only at shows and on trails. I can't really work with her on kicking at shows if I don't take her to any. It also helps that aside from the warm-up pen and fun classes, I run games such as barrels, poles, etc that I don't have other horses in the arena with me when I do my classes. But just because she has a tendency to kick, I'm not going to keep her from the show environment and hinder her training.
It's a joint-responsibility to ride a horse, not just the sole-responsibility of the riders with horses that have less than impeccable manners. Posted via Mobile Device
