My 11 year old QH/Trak. gelding still likes to spook "for fun" I've
been riding him since he was 2 mostly in Dressage, but some combined training
also, and if I let him "get bored" he will find something to spook
at. But I love his personality, he actually HAS a personality and
I'll take the occasional spooking. He's a very confident horse, loves to
lead on the trail, spook, snort and pretend to buck (baby buck).
