Eh, ya I have heard o' this. It's an inflammation o the foot. It's really, really painful. I causes tissue damage. The worst cases of lamintis cause problems with the coffin bone and hoof wall. If it's bad enough the coffin bone could get rotated and it'll go through the sole of the horses foot and ta the ground. That is what happened ta my friends horse, oh my gosh, it was so horrible I got sick when he told me 'bout it. This is the worst case senario though.
