This results when the toe of the hind-foot strikes the heel or coronet of the fore one on the same side. Somewhat serious wounds are occasionally inflicted by this movement, and horses are not only lamed, but riders are sometimes dismounted, and suffer serious injuries in consequence.
Fig. 406. - Overreaching A, Point of Contact. Toe of Shoe with rounded inner edge.
The damage to the fore-foot is inflicted by the inner margin of the toe of the hind shoe, and not, as is frequently supposed, by the front or outer edge.
This accident is favoured by that peculiar conformation in which a short body is set upon long legs. Animals low in front are also more predisposed to overreach than others of the reverse type, and the danger is augmented -. when the hind-feet have been allowed to grow unduly long.
It mostly results when horses galloping over heavy land fail to get their fore-feet clear away from the ground before being overtaken and struck by the hind ones. Jumping on to rising ground, or being suddenly checked when going at racing speed, are not uncommon causes of the mishap.
As a means of preventing overreach, the hind shoes should be rounded on the inner edge of the toes. If the hind-feet are overgrown, they should be shortened and the shoes well set back behind the margin of the toe. The fore-feet also must be kept within reasonable limits in regard to length.
