Hey you aussies out there starting my arab x stock in barrels any pointers?

first walk him around the barrels if he doesn't no what he is doing at a walk he won't no what he is doing at a gallope. so walk him around the barrels. also gaming the horse has to have a drive to do it. i kinda sounds like your horse doesn't have the drive to turn the barrels. if that helps. also never heard of the tires and trust me i have heard a lot hope that helps. also if u really want to get into barrel racing try a quarter horse they are the best the have the rump to turn the barrels
