I'm still new to how headsets and body carriage should be for Dressage. Could you help me understand better what exactly he is doing wrong with his head set. I'm having a hard time seeing it but I know that's simply because I have untrained eyes, I'm trying to learn.
He is GORGEOUS though. What breed is he?
He is doing nothing wrong. He is a young stallion and showing off. Notice that he is perfectly capable of lowering his head as he did it several times.
There is no hollowing of the back but there is the tension exibited by a stallion that you will often see especially by a young stallion in an arena where he can smell other stallions. To mistake this verve for incorrect or too high headset is common and once you have seen these young stallions going for their 100 day testing you will see an entirely different picture.
I have seen several stallion shows and you have to go to one to understand the excitement it generates for man and beast.
