This is a very brief post as there is not very much to write about over tracking, tracking up and under tracking.
Over tracking: Over tracking is when the horse's back hooves overstep where its front hooves were.
Tracking up: Tracking up is when the horse's hind hooves step exactly where its front hooves were.
Under tracking: Under tracking is when the horses hind hooves don't quite reach where the front hooves where.
