What is/What are the best resources to learn about warmblood bloodlines? (books, videos, websites, etc.) I don’t have a specific breed in mind, focus would mainly be Dutch warmbloods, hanoverians, Oldenburgs, Holsteiners etc and dressage sport bred but any information of resources to learn about any lines would be amazing. Is there a/are there resources out there to get this information? I just very much want to expand my knowledge and learn.
