When A Horse Founders What Does That Mean?

Founder is the common name for laminitis, a condition of the hoof in horses and donkeys. Within the hoof, there are structures called laminae that attach the hoof wall to the coffin bone. When a horse is foundering, these laminae become inflamed, the blood supply becomes compromised, and they break down.
