She said horse was trained & ridden western classes primarily.Well western encompasses alot of different disciplines just not WP
,don't remember reading that horse was WP bred either,AQHA have many different types in pedigree,not all are the low & slow types.Also what level at what level was she shown? How polished & engrained was this lope?Seems like Alot of assumptions being made about this horse ..... despite popular stereotypes yes AQHA horses can & do excel in jumping. Horse is learning something new & yes sounds slow is her primary language
not to say that can't change once horse learns more & may find this is more fun
.I say let the OP keep working with her,this is all still pretty new for her & you 2 together. If it continues to be a battle & her heart isn't in it,yes find a horse that is.
Remember my first horse ,I wanted to barrel race & pole bend on her. When I first broke her I had to carry a stick to get her to move,cantering was too much work.
doing a trail course Or leisurely pleasure ride seemed more her speed. Well I pursued training her to the patterns anyway & before long she found her calling!! Made Honor role & world show qualified
