This may be something I need to move more to the sport horse breeding forum, but I think this would be more practical to ask hunter/jumper riders and trainers who are currently showing in the industry. Bare with me as I more of a dressage rider and have very limited experience with rated hunters, but was having this discussion with a few friends and wanted feedback and thoughts.
This is an overwhelming generality, but basically, is it physically possible for a 14.3-15.1hh horse (or as some would considered them, “honies”) to be suitable in the Amateur Owner or Amateur Divisions (3’3", 3’6") at shows? If hunter breeders produced a horse at this height, would riders be able to make them successful in the amateur, junior, medal classes, etc.? Would this size of horse even be considered for a professional division? How often are horses this size capable of a 13-14’+ stride at this size? Would they sacrifice form and pace or are some of these smaller hunters capable of doing these divisions? Or do trainer and riders typically place these sizes in the small hunter or small junior hunter divisions or the unrated pre-childrens, pre-adult, etc. divisions?
As far as jumpers, would these sized horses have a more fair shot (as long as they have the scope, speed, talent, etc.) at being successful and marketed?
At 5’1" I don’t ride anything bigger than 16 1/2hh in the dressage ring and most of my horses are in the 15.1-15.2hh range, but I can see why a larger horse may be more beneficial to make the higher divisions look “effortless” for a horse in a hunter division. Do you think this is the/a main reason the majority of riders and trainers typically lean towards horses 16hh plus? Is there a market for purpose breeding a smaller sized hunter - perhaps for more petite riders - or are they usually just breeding “accidents”? Do you think this may change in the future at all?
I’m curious to see everyone’s opinions!
