Horse with unwilling attitude
I just want some advice on my horse. I've had him for almost a year he is a young warmblood (5years) that I purchased as a jumper/eventing prospect. He is really talented, beautiful gaits, super fancy, amazing scope, but he has a bad attitude. Its hard to explain his attitude. I think my trainer explained it well in he is just not willing to try for you. This horse can clear a 4 foot oxer with absolutely no problem but when he is done (not because he is tired he just decides he doesn't want to work anymore) he will just run out of a 2'6" vertical that he just jumped 4 times previously without an issue. Also when he is "done" he will just try to leave the arena or bolt off and when I get after him we will get into this bucking war in which I win the battle but never fully win the war.
I recently had a clinic with a well known eventing rider and she told me that I should get rid of him. She told me that he has all of the talent in the world but its between his ears. It was kind of a shock as I've spent a lot of time/money in the past year and its hard to accept that I should get rid of by far one of the most talented horses I've ever ridden.
I guess my question is does anyone have experience with this type of attitude? I understand that he is young and a lot of people have told me that these things take time but I don't know if I should keep trying or cut my losses.
I should also add that he is completely sound, not back sore, his saddle fits, his x-rays are clean, etc. I got him with basically a clean slate and my trainer has rode him a bit and she doesn't want me to make a hasty decision but she is worried that I may spend months/years trying to make it work or paying her to make it work and it may just never be right.
