Spots on the brain

There will always be a fight between the different horse breeds, quarters and paints are not best friends, neither of them like the appalosas and the arabians are not that popular either. I have a quarter horse and will never again have any other breed. Iv had an arabian, and he was very very nice but those are rare. Alot of arabians are "spooky" and are not that easy going. Iv had a paint and he was okay too, Im just not a big fan of the colors..Iv never had an appalosa but I have ridden one when I worked in Germany...he was a pain in the ass...Rocky...Rocky the stallion..He was in training with us for a stallion presentation where they show the appi studs so they get approved to be just in breeding or something like that. The presentation was devided in different parts, there was a reining part, pleasure and a trail part. Since my boss had no interest what so ever in pleasure and trail I was the one who got to get Rocky ready for this presentation. Appalosas are famous for their spots, but its not just on their skin they have them..A lot of them also have spots on their brain..and so did Rocky..He was the "studdiest" stallion we had, I had to have help when I walked him to the arena so he wouldnt stop outside some other horses stall and strike at them with his front leg. But once I got on his back he could be an angel! He moved really nice and listened very good to be in the trail, but every now and then Rocky had a bad day, and when he had a bad day, so did I.... As long as I would just sit on him and let him do and go wherever he wanted there was no trouble, but if I just touched him a little bit with my spur or leg he would go mad..He would buck, kick, jump or do anything to get me off his back. The good thing was that he was so big and breed to be a pleasure/halter horse, they are not so athletic so his movements were very slow and big. It was not hard to stay on him but there is always a chance, and since he was a stallion he would probably try to fight the other horses in the arena if he came loose.
My boss didnt want to ruin his reputation by having a crazy appi in the barn, or risk the lifes of others so after the stallion presentation we decided it was time to send him home.
Rocky had amazing color and looked good, but he did have spots on his brain...and thats what I dont like about the appi world, it has so much to do with color. They will probably breed mares with Rocky, and get beautiful offsprings that might win alot of halter classes, but who knows how they will be in the head...Thats one of the best thing with quarter horses, color does not matter, its more important to have a good minded individual than a flashy halter class winner.
