The Successful Dressage Competitor, by Debby Lush
If you compete or are considering competing in dressage, this will help prepare you and your horse to perform your best. From proper attire and attitude to evaluating the judge’s comments after your ride, Lush gives helpful suggestions, supplemented with color photos. She explains what the judge wants to see for each movement, how to ensure that you get it, and how to fix it when it’s wrong. This is one of the most useful books on dressage competition that I’ve seen.
