Of course!! My best friend has a quarter horse doing 2nd level dressage! They may not excel in the upper levels, only because that is not what they are bred to do, but they can definetly do it to a certain extent!
Of course a quarter horse can learn jumping and dressage. However, there is still a saying, the mule with the most heart can't win the Kentucky Derby. Or something like that. Breeding isn't everything, but it is mostly why a horse is successful in their given discipline. If you want it just for pleasure then sure, or even if you want a horse to take you up the lower levels. But once you get to the upper levels, you see less and less of other breeds and more and more of warmbloods. You don't really see thoroughbreds anymore, though around 50 years ago they were known as THE sport horse for really any discipline. The sport changes, horses change. The reason why Grand Prix jumpers and dressage horses are all warmbloods is because they are bred to be the best in that discipline. My point is, basically any breed has potential for any discipline, but they just might not fit that discipline in the upper levels.
Hi Paris 🙂
It's not their first quality but of course they can be really good at jumping or dressage! I think it depends a lot on each horse, and on how you ride and train them.
If you teach a young horse how to use his qualities for the discipline you like, and if you feel like he likes it, then there's no reason why he couldn't do it with all his heart 🙂
