Yes, a tremendous chunk of the reason I bred Whiskey is that she is no longer sound. But you could also say that she (her genetics) are the last of a long, venerable breeding program from a historic ranch (she was purchased in the dispersal sale). You could also look at her trainablility, personality and athleticism. She is a stellar creature to be around. And was a wickedly fun ride. (I've NEVER had a horse pick up and do flying lead changes the way she can.) Is she proven? No. But that's my fault and shouldn't reflect upon her ability.
The stallion I'm breeding to is proven. He's won money at reining events. Plus, he has the added bonus of old genetics up close (he has King on his papers). As well, he demonstrates an excellent disposition and high levels of athletic ability. These are all qualities needed to make a performance horse.
And this baby will be headed into the performance arena. Preferably cutting, but if not suited to that world it will be trained in a discipline that suits it and be a constructive and contributing member of the horse world. Responsible? Or adding to horse overpopulation?
