What are your thoughts on "dressage?"?

Dressage is where they take a horse’s natural gait and create a highly stylized form. The Lipizzaner Stallions are famed for it. This is the most incredible example I’ve ever seen.

There is a debate raging on fb with one person saying that the training techniques are abusive and the gaits cause injury to the horse. From what I’ve seen, quite the opposite is true. This PBS documentary goes into quite a bit of detail regarding the selection and training of the horses. They’re pampered and loved.

Any thoughts on it yourself?
