That horse does Dressage very, very well. Whenever I go to my events, I often watch the horses being warmed up to see how "loud" the tail is. The steadier the tail, the more the horse "gets it" rather than being forced into it. Some rides you can look at the horse and just know its pissed to high heck about the ride and that it is very, VERY tense and being shoved into false bends. Its amazing that some of the Grand Prix horses I watch perform actually PASSED the lower levels because of the amount of resistance they have in every single ride. e.e;; This is why taking your time in training is important. This horse shows us that!
This horse really gets it. The cues on the rider seemed a little loud to me (usually I can't watch the horse being asked to perform the next move, but in this video I could see every transition through the rider's legs) BUT.. i am MUCH happier/satisfied/impressed to see less subtle cues if it means the horse is supple and willing. The horse gets it, and the pair look like they are working with eachother, not against eachother.
Thanks for the share Spyder!
