Actually, while this horse has a roach back and a ewe neck he might be ok for pleasure riding. He will always be stiff and may never be able to use his back.. but he may be just fine.
He is posed terrible and it is not helping at all. He also needs about 150 pounds or more.. and weight would help him a lot.. along with a better stance for a photo. This photo does him NO favors.
Sometimes you see this.. even in well bred horses. The genes come together and it is not so good. This horse has some good stuff.. looks like good legs and a very short back... decent sized feet and an ok shoulder. He may not be as bad as this looks with some weight.
