Oops, didn't finish there😂. Well, anyway, those are just a few exercises one can use. The problem that most riders face is just simply not caring and letting them just figure it out. Sounds strange, right? You see, I've found that some horses actually do better in situations like this if they cannot get a reaction out of the rider. This usually works on young or snarky horses that are just testing g the rider's boundaries. Correcting with leg aids and a touch of the rein when a hose goes beyond just looky or shying is essential, but horses fishing for attention by spooking at unnecessary things like that pitchfork that has been in the arena for the past two months just really need to learn that you can't get anything out of being bad, and that it uses more energy to spook than it does to deal with it. It doesn't work for every horse, but it certainly does on others. For more instruction look up "schooling spooky horses: evention TV" on YouTube.
The goal is to keep him busy and engaged, wich can be pretty hard for a young horse. Changing direction, schooling excersises that solidify the horse's understanding of transitions, and doing exercises with trot poles and small cavaleties,
Change things up as far as arena work goes. I find figure 8 and circles keep them focused
Groundwork groundwork and more groundwork! Building a solid relationship on the ground will transfer undersaddle and you will find your horse to be much more responsive. Also try to be calm yourself (I know it's easier said than done!) but if your always tense and anticipating your horse is going to spook then chances are that he will. So next time your riding try taking a few deep breaths and focus on relaxing your seat and gentling your hands. Also remember he is only five years old so it's very natural for a horse of that age to be energetically and spooky as he is still a baby 😋
Take away the bit, try out a rope halter as bits can be painful and make horses more nervous
Expose him to the things that spook him more often. Maybe spend a day each week just taking him through mini obstacle courses to help him get used to the things he may be exposed to.
My horse is very spooky but I have noticed he focusses more and he is less spooky when he is ridden more frequently
Sometimes wiggling ur reins and turning his head to the inside
