Any Dirving Horses

[SSMFarm]

I was just wondering if there are any folks that use Body Builder (previous or ordered from me) on their driving horses? I don't show in driving and am being asked about doseage for a driving horse in training. I am sure that my halter horses in training are probably not getting the exercise/work out daily that a driving horse does. If anyone will share that info I would be most appreciative.
