Natural Barefoot Trimming and Hoof Rehabilitation by Richard Zewe
What is Founder? What is Laminitis?
Laminitis is inflammation in the Laminae or the connecting layers called the Epidermal and Dermal Laminae which form the tight connection between the hoof wall and the internal structures (the coffin bone).
Founder then is when that connection has totally pulled away, and the coffin bone "drops" or "sinks" through the hoof capsule. Actually the coffin bone is not moving (it's still in the same place) but the hoof capsule is tearing away and rotates away from the coffin bone.
This mare is one I still work on.
A fairly common site in our domesticated horse.
The feet of this Mini were badly neglected by the previous owner, the horse could barely walk at all. After the trim she walked off wonderfully happy with her new found feet. Still more work to do but it's a start in the right direction! See a video of Cookie moving out now with her new feet on the Video Page.
This is Cookies feet again just two trims removed from the first photos above. She's moving really well now.
In the foundered hoof image on the Left, notice the hoof wall pulling away from the Coffin Bone (P3). Leaving the Toe long on a horse like this promotes the continuing ripping and tearing of the Laminae and causing the horse pain. In the image on the right, notice the good tight wall connection between the hoof wall and the Coffin Bone (P3).
