Abstract: An equine frog support system, comprising a support base constructed of a material, preferably a thermoplastic material, molded to conform to the frog and collateral sulci of an equine foot, the material being sufficiently rigid and fully elastic during the use thereof to support the frog and the collateral sulci; and a wrapping or other device for holding the support base against the foot. Preferably, the support base is shaped to support only the frog and collateral sulci of the foot. Also, a method for treating equine laminitis is provided, comprising the steps of placing a softened hardenable material, preferably a thermoplastic material, over the frog and collateral sulci of an equine foot. While the material is in a softened state, the animal is caused to place weight on the affected foot, thereby compressing the material between the ground and the foot.
