the faults are always manmade , farriers not heeding the instructions on application , resecting the hoofwall and then appling directly without putting a barrier between the laminae and the vettec or whatever they are using , stripping the wall and building superfast too thick too quickly , do it yourself on a piece of cardboard then put you hand on it firmly for 30 seconds , tel me its not effin HOT , immature feet as well you know are very soft thin and sensitive to any outside applications , vets and farriers are too often starting manipulations too early IMO
