I followed a link posted by a COTHer on a thread about stallion registries: the WBFSH World Ranking List, Studbook (Jumping) as of July, 2019. A striking number of competitors were sired by Chacco Blue. (On the dressage side, Sandro Hit seems to come up quite a bit.)
Now I’ve heard that Chacco Blue’s offspring tend to be difficult–stubborn and quirky. Whether or not this characterization has any merit, where might I find out more about the kind of temperament a particular stallion may pass on to his offspring? Is there nothing to rely on but folklore passed from one rider or trainer to another?
