I have struggled with this same problem. Mine eat Cool Stance and Power Stance. Coconut with nothing added. Feed is baked coconut at real low heat, 18 Amino Acids naturally occuring, and has the oil in it. For added, hoof health, weight gain, or weight stabilization for crested neck, the Power Stance is a powdered Coconut Oil. They look beautiful, health hooves, no more White Line, it is the LOWEST Sugar/Carbs on the market, so is a Cool feed. Less that 12% starch, and huge amount of fat, that is the good Medium Chain Triglycerides, that are good for you. Good for the dogs, and cats, too. I am the Texas Distributor, have lots of it in Houston.
