Look Inside a Hoof with White Line Disease

The photo below shows a closeup view of a hoof with a fairly advanced case of white line disease. The infection has destroyed the inner unpigmented layer of the hoof wall, leaving behind a v-shaped slot between the dark-colored outer wall and the yellowish white line.

Because it is difficult to medicate the active disease at the top of such a deep cavity, the hoof wall has been cut away and diseased tissue has been removed.

White line disease is an infection that can attack and destroy large areas of your horse’s hoof wall.
