I have a half arab saddleseat horse. Since there are no shows until April. I have pulled him out of his double and am now riding him in just a snaffle and martingale. I had draws on him but stopped because I want him to learn to carry himself in just a snaffle and martingale and be lighter in the mouth, I don't want false collection from the curb. He either has a very hard mouth or is running through the bit. Instead of him rolling over, he sticks his nose out in the air. He carries his neck very high which is fine cause he is a saddleseat horse. I think a lot of the problem is he is out of shape, he never will be in shape like he used to be cause I can only work him a few days a week cause of my job and the fact that I only have an outdoor round pen with no lights. Basically I want him to learn to carry himself, be collected in just a snaffle without the use of draw reins or the curb on his double bridle, and to driver under himself. I am having a vet come out but I think he needs a chiropractor or massage therapy because he is stiff on the right side of his neck and in the rear, he also doesn't like to be saddled, has a very large mass of scar tissue from an accident before I got him, pins his ear for the 1st several minutes of the ride, he also hates to get his blanket put on and to be brushed. I know this is kind of everywhere but any help you guys could give would be great.
