Hi! I was just reading your 2012 thread on LLD.
im just now starting to treat my mare for that exact issue.
it so happens to be that the higher heel IS the shorter leg. The other leg she postures forward and/or puts more pressure on it which causes it to be a flat growing foot.

Therefore I believe your original farrier was correct in adding a pad to the clubbed foot.

How have things panned out over the past 5 years?
