If a horse can be bred to have "cow", can it not also be bred to have "bull?"

Rejoneador Deigo Ventura's mount above is attempting to "mordisco" the bull. Mordisco is a superb word, better even then Ankus, which allows us to manage elephants but not train them, because translated Mordisco means "bite" or "nibble" covering both the realist with bite and the alibier with nibble. Perfect political correct harmony. Now that "whips" have become "pointers and carrot sticks" I suggest that we revert back to the term "irons" for "spurs", as the quote, "spurring his mount on," might give the wrong impression, where as "ironing his mount on" kinda makes you envision your mother lovingly getting your Sunday go to meeting clothes ready for you.




The above clip from the 50's is of cutting horse legend Billy Earl, exhibiting what is known as "cow", short hand for "cow sense" or an innate/hardwired desire and ability to read and anticipate a cow's mind and actions, which can then be further refined through training. Is Deigo Ventura's horse not exhibiting that same innate/hardwired desire and abilty to read and anticipate a bull's mind and actions, which has been further refined through training? Or is Diego's horse just being a prick, given what man has "forced" him to do, kind of a PTS Syndrome deal?
