I can not see any harm that I have done to my draft trough dressage training. And no I am not just interested in upper levels. I am interested in improving my horsemanship and training by teaching a horse not traditionally built for dressage.
So from my point of view I knew exactly what I was getting into. I knew that I was going to have to work for every gate, extension, and collected movement. I am in it for the challenge. I have no delusions that Rocco is my gp horse. But he is the horse that is teaching me how to work through issues that all young dressage prospects have. I cannot speak for all drafts but from my experience with my draft is that he is smart, willing to work everyday, if you are not correct with your aids he will call you on it.
The non draft people are correct about one thing with drafts you will have to put in a lot more time in to drafts than horses more traditionally suited for dressage. But how many talented horses from more “traditional dressage breeds” were sold as horse not capable of higher levels because the trainers didn’t have the time that some of the horses need to develop. The animals are individuals no matter what breed.
Professional trainers are running a business they need to prove that they can bring horses along in a trimly fashion and they need to keep their clients happy. So if a horse is not moving at the pace that they like the horse is sold. I am not a professional trainer I am in it for the art of dressage and the challenge of training horses. I am in this for the rest of my life I do not need to do 4th level tomorrow. And as long as my horse is sound and can do the work we will be doing dressage until it is time for him to retire. Which I think will be a long time considering he is in better shape now than when I got him living the life of a retired plow horse. Yes my draft was a working plow horse with the scars to prove it. And I think he Digs his work a lot better now.
