If his feet need to grow stronger and healthier, I suggest a pelleted supplement called KOMBAT BOOTS, it is made of dried brewers grain and yeast which is high in biotin. It also helps with stamina and energy, and helps prevent ulcers and colic (ph level). It is not currently offered through smartpak but it can be ordered by the retailer online. My (1100lb) paint mare gets 1/3 cup twice a day and her feet are great now, we ride on very hard ground too. Sometimes thrush makes her sensitive though. Good luck!
