The Art of Horse-Shoeing: A Manual for Farriers

by William Hunting

Outline fitting. A shoe is first compared with the foot, it is then heated, and the heels cut off or turned down to the proper length. Each limb of the shoe is fitted to follow the outline of the wall, and it is necessary to warn the novice that the inside and outside borders of a foot are not alike. The outside is rounder and fuller, and the shoe should be shaped to follow exactly the direction of the wall. The outer border of a shoe should always be as prominent as the outer border of the hoof; it should never be within it. The inner border must not protrude beyond the wall lest the opposite leg be struck. A well fitted shoe must be fitted full to the foot. What is called "close" fitting, i.e., bringing the shoe rather within the circumference of the wall, is injurious, as it loses the best and strongest bearing of the wall, and permits the farrier to give an appearance of neatness by rasping away any horn which protrudes beyond the shoe. On a well-shaped foot the shoe should follow the outer line of the hoof from toe to heel, but where the heels of a foot are turned inwards there is an advantage in fitting the shoe wider at the heels, as by so doing the base of the foot is not constricted and a wider resting surface is afforded to the limb. When a shoe is fitted wide at the heels it is essential that the foot-surface of the shoe should be level at the heels. If it be inclined, as it often is in seated shoes, a very grave defect in the fitting results, for the heels have no level bearing-surface.

A shoe fitted too wide is liable to be trodden off by the opposite foot, or it may cause the horse to hit the opposite fetlock joint.

Provided the nail holes are properly placed, when the outside border of the shoe is fitted nicely to the circumference of the hoof, they are brought to their right position. When nail holes are placed too near, or too far, from the outer border of the shoe—i.e., when they are too "fine" or too "coarse"—it may be necessary to correct their position by fitting the shoe "closer" or "fuller," as the case may be. When a farrier fits shoes made by another man he may overlook this, as we are all slaves to habit. The man who in his daily practice combines "close" fitting with "fine" nailing has to alter his routine when fitting a shoe with coarse nail holes.

The length of a shoe at the heels is a matter of more importance than is generally recognised. As a rule hunters are all shod too short, while most cart horses are shod too long. The objections to a long front shoe are that it is liable to be trodden off by the hind shoe, and that it may injure the elbow when the horse lies down. A long hind shoe is free from both these disadvantages, and as it usually has a calkin is the best form to adopt.

In fitting the heels of front shoes, in all but galloping horses, the iron should generally extend slightly behind the extremity of the horn. ([Fig. 48]). Horses used for galloping should have the end of the shoe just within the termination of the horn, and should finish with an oblique extremity. ([Fig. 49]). There is nothing gained by greater shortening, if the iron be fitted exactly to the horn. Why shoes are often pulled off, when only just the length of the hoof, is because they are not fitted close enough, and very often because they are wilfully and ignorantly designed to leave a space between hoof and iron. This so-called "eased" heel is an unmitigated evil.

Surface-fitting. It is simple to direct that the bearing-surface of a shoe should be exactly adapted to the bearing-surface of a foot. It is not so simple to carry out. When the horn on the lower surface of a foot is thin any uneven pressure—i.e., pressure applied directly to one spot—soon causes injury, pain, and lameness. When a good thick layer of horn exists, uneven pressures are less injurious, because the horn distributes them over a wide surface. Good workmanship is displayed by leaving no uneven pressure, and by so fitting a shoe that it shall do no harm. With a narrow shoe—one only the width of the wall—no uneven pressure can be applied to the sensitive foot, but such a shoe is seldom used as it is too light to afford sufficient wear. A wide shoe with a flat foot surface is easily fitted on all concave feet—i.e., on all hind and most fore feet. To make use of the whole bearing-surface a shoe must rest evenly from toe to heel—the flat surface of the shoe must take a level bearing on the whole flat bearing-surface of the foot.

There are two places where injury from uneven pressure is most likely to happen—at the toe and at the heels.
