Conditioning, grooming, and training a horse for showmanship cannot be done quickly. Sometimes readying a horse for show takes three to six months, depending on the time of year you start, on the age of horse, and on how quickly the horse responds. Conditioning Get the horse in good health. Put your horse on a regular deworming schedule. If possible, take fecal sample to your veterinarian, and deworm based on evaluation.
Force exercise the horse regularly.
This may be done under the saddle, loose in a pen, or on a lunge line. Exercise removes excess fat, adds muscle tone, and makes the horse look like an athlete. Trim feet when necessary. Don't let lack of trimming cause incorrect action or conformation. Train the horse to lead correctly.
