        Shoeing  is  necessary  to  prevent  excessive  wear  of  the  feet  when  horses  work  on  hard

        surfaces.



        The principles of trimming and shoeing

        Correct  trimming  and  shoeing  is  essential  for  long-term  soundness  of  the  working  horse.

        Most horses are reshod every 4–6 weeks but this depends on the hoof conformation, horn
        quality and the use of the horse. If they are left for too long the following problems may

        arise.
        •    The foot will become unbalanced because the hoof wall grows faster at the toe than the

             heels. The wall at the heels may be worn by the shoe as the heels expand and contract;
             hence  more  horn  is  usually  removed  from  the  toe  when  shod  horses  are  trimmed.

             Conformational defects may lead to exacerbation of any hoof imbalance.
        •    The hoof wall may grow over the outside edge of the shoe at the heels; the shoe then

             presses on the sole at the seat of corn causing bruising and lameness.
        •    The clenches begin to rise and can cause brushing injuries.

        •    If  a  loose  shoe  is  wrenched  off,  the  nails  may  tear  away  large  chunks  of  hoof  wall,

             making subsequent shoeing difficult (Figure 6.6) or cause soft tissue injury and lameness.
        •    The horse may suffer serious injury by treading on the nails of a twisted or cast shoe.
