Poles and simple grid work.
Do lots of poles for a while until they gain their feet. After that, slowly work up
Thank you guys! Clients horse and she has very little equipment, so makes it tricky to build some stuff.
You can first do a lot of pole works to help him get confidence and then when he is confident on the pole work, do the same with small jumps. Always remember to keep the exercise very easy for the horse.
If he succeed all the small exercises, he will gain quicky confidence!
Good luck, hope this helps :)
