Push the A button to goto the next screen which will show your horse...After you see your new horse don't proceed!!! This is where you can kinda cheat... Hit the back button and that will take you back too the disections of DAM & SIRE... Hit the next button and this will give you a different horse with different stats everytime you hit back and goto the new horse again... Watch the ABILITY stats closely!
