Was just pondering this on the school run! It's one of those bits of horsey terminology that seems to cover a multitude of sins. I'm still not entirely sure I've completely figured it out. Would you say a spooky horse was a sharp horse, for example?
No I wouldn't say spooky tho that can be part of the "sharp" package. I would say with a sharp horse there is very little room for rider / handler error. They learn fast and can just as easily learn the wrong thing.
To me it's a horse that's very reactive/over-reactive, both to the rider & outside stimuli. It doesn't mean a nasty or naughty horse, though if the rider is out of their depth it can feel that way. Usually need calm, competent, focused riding - not necessarily just for professionals because sometimes the relationship is as important as ability, but certainly not for a novice, nervous or switched off rider.
