A great deal of the lameness or lack of acivity
that horses exhibit come from hoof abscesses. They occur
when objects get into the hoof; such objects are occasionally called ‘gravel.’ The foreign object can lead to an infection
in the hoof that can be quite painful. Hoof abscesses can
also be caused by something sharp having pierced the bottom
of the hoof.
If left untreated, a hoof abscess will get worse.
