The equine bulb is formed from keratin in the same manner as the sole and again this keratin is softer and more liable that the keratin found in the hoof wall. The frog ensures that the wall of the hoof is forced outwards when weight is put on the limb thus ensuring that the 'hoof mechanism' functions correctly and ensuring circulatory flow around the hoof and back towards the heart. | The equine bulb is formed from keratin in the same manner as the sole and again this keratin is softer and more liable that the keratin found in the hoof wall.
