Horseshoeing is a vast and complex art and science, and it has many areas which will not be discussed here. Rather, I will limit its discussion to the proper shoeing of the normal working horse. The average Quarter Horse with a sound healthy foot will be considered the normal working horse for the purposes of this article. It must be remembered that horses with a gait or conformation problems will be shod as variations to the normal.
