A Text-Book of Horseshoeing, for Horseshoers and Veterinarians

Left fore-hoof of normal position shod.

Between the ends of the branches and the frog there should be enough room, with few exceptions, to pass a foot-pick.

In order to judge of the width of a shoe which has been fitted to the hoof, it is of advantage to seize the hoof in the left hand and, extending it towards the ground, to observe from behind and above the outer border of the shoe and the surfaces of the wall.

Furthermore, the most important rule is that the shoe should always have the form of the foot, so long as the form of the hoof remains unaltered. In all hoofs that have already undergone change of form we must strive to give the shoe that form which the hoof had before it underwent change. Such treatment will not only do the hoof no injury, but, on the contrary, is of advantage to it, as it is well known that in time the hoof will acquire the form of the shoe.

Shaping and Fitting Shoes.
Special Considerations.

(a) A shoe for a hoof of the regular form fits properly when the outer border of the shoe in the region of the nail-holes closely follows the outer edge of the wall, but from the last nail-hole to the end of each branch extends beyond the wall from a sixteenth to an eighth of an inch, the shoe is straight, lies firmly and air-tight upon the bearing-surface of the hoof, the nail-holes fall exactly upon the white line, and there is sufficient space between the frog and the branches of the shoe for the passage of a foot-pick. The branches must be of equal length.

While in fitting a shoe to a hoof of regular form we need pay attention only to the form of the hoof, it is very different when we come to shape and fit shoes to hoofs of irregular forms. In these cases we must consider not only the form of the hoof, but the position of the limbs and the distribution of weight in the hoof, because where the most weight falls the surface of support of the foot must be widened, and where least weight falls (on the opposite side) the surface of support must be narrowed. In this manner the improper distribution of weight within the hoof (an unbalanced foot) is regulated,—that is, is evenly distributed over the surface of support. The manner in which this is accomplished in the various forms of hoofs is as follows:

(b) An acute-angled hoof requires the shoe described in [paragraph 2, page 114]. The branches must be long, because more of the weight falls in the posterior half of the foot, and long branches extend the surface of support backward, while the surface of support in front is to be diminished by making the toe of the shoe base-narrow, either by turning it up or by bevelling it in under the foot. A shoe for an acute-angled hoof fits when it is otherwise related to the hoof as is described in paragraph a, above.

(c) An upright or stumpy hoof presents exactly reverse conditions with respect to the distribution of weight within the hoof, and is treated in an exactly opposite manner. The surface of support should be increased at the toe and diminished at the quarters. This is accomplished by a shoe possessing the peculiarities described in [paragraph 3, page 114], whose nail-holes are directed either straight or slightly outward.
