Siegreich in Dressurpferde A

Our 5-year-old gelding was gently backed last year to give him enough time to mature. In the meantime, he has competed twice in the Dressage Horse A class, finishing 5th and winning the second time (8.4). He showed himself to be completely unflappable and uncomplicated. In training, we are working on the L-level exercises.  
His brother was already highly placed in M-level dressage at the age of 6.  
At 2.5 years old, he was X-rayed, with no findings.  
He comes from our own small breeding and has a very pleasant, kind character; he is exceptionally friendly with all people and horses. He is, of course, familiar with pasture, whether alone or with others, round pen, washing, clipping, loading, and commotion at the yard, etc.
