CORRECT ACTION IN HORSES
While it is the intention of this article to endeavor to picture ideally good action, by which wear and tear and loss of power are reduced to a minimum, it is not intended to decry the possession for certain purposes, by a horse, of what is usually called high action. To render horses attractive for show and for pleasure purposes it is a highly desirable quality and very much increases their market value. The good horseman would much prefer, however, to sit behind a horse with moderate action, that raises his feet, advances them in a straight line with stride enough to insure desirable progress—yet not so much that the feet cannot be put down squarely—every part bearing its proper proportion of weight and striking the ground lightly, than one with excessive but markedly defective action. High action, like other qualities possessed in a high degree, is very apt to be associated with defects that detract from its perfection and lessen a horse’s wearing quality. The ill-consequences of these defects are intensified in direct ratio to the excessiveness of the action. The craze for high action at any cost is not so rampant as it used to be some years ago. Horse-show promoters became wearied of seeing their premiums for action carried off by acrobatic monstrosities, and it caused them to modify the wording of their prize lists and call for all-around goers with twenty-five per cent. for conformation. The horse that winds his legs about, “straddles,” “points,” “rolls,” “spreads behind,” “waddles,” or drags his hind legs, is no longer in favor with the good judge, no matter how excessive his action.
The character of the action is a very important factor in determining the amount of wear and tear a horse will stand. To become a good judge of action is not such an easy matter as might be imagined. There are many who have a good eye for a horse, and, in fact, are, in a measure, good judges, who cannot intelligently criticize a horse’s action from different standpoints. There are many who are taken with flashy action, which, as a rule, enhances the market value of a horse possessing it, but is very apt to be associated with greater defects from a utilitarian standpoint than that which is less attractive. In estimating the quality of action correctly in different individuals one has to have an ideal. How seldom in sitting behind a horse and closely observing his way of going at the trot and walk, do we find action that comes up to our ideal! Perfect action, as far as usefulness is concerned, is frictionless and light, and the foot is placed on the ground squarely. There is no loss of time or power in progression, or, in other words, the frictionless mover does not labor, neither does the light-stepper experience the ill-effects of concussion, which is the result of bringing the foot to the ground in a pounding manner. What a saving of wear and tear and power the smooth-mover and light-stepper experiences! One is amazed in instances to observe how much work a weak-footed, poor-legged horse will stand and still remain in workable condition. It can be accounted for in many cases by the defects mentioned being compensated for by light action.
It is interesting and instructive to study the numerous and varying conditions that conduce to defective action. Lightness of step appears to be a quality not always dependent upon the conformation of the individual. For instance, length and obliquity of the pasterns are usually said to cause lightness and elasticity of the tread, but do not always do so, for we find many heavy-going horses of this formation. Mechanically, this should conduce to light-stepping, and does in a measure, but the fact that horses with oblique pasterns sometimes pound, leads us to look for another explanation. The statement may be advanced, in explanation, that the elasticity resulting from oblique pasterns may be neutralized by a straight shoulder; but this theory will not hold, as one not infrequently finds straight-shouldered, short-pasterned horses which step lightly. Another explanation must be found. We have to seek elsewhere in the animal economy than in the peculiar arrangement of the bones, muscles, tendons and ligaments of the limbs to account for the light step of some horses.
The endowment with this desirable quality is undoubtedly referable to the nervous system, just as speed is. We cannot determine the degree of a horse’s speed by studying his external form. We have to subject him to a test, and so we have in forming a conclusion as to the degree of lightness or heaviness of his step.
With regard to labored progression, the tendency to it is usually determinable by an inspection of a horse’s conformation. All deviations from the steadily carried top in the trot, in which there is no rolling, jerking or waddling, and from the straight flexion and extension of the forelegs, in which there is no straddling, dishing or winding-in, and from the equally straight and easy flexion of the hock, can, as a rule, be determined by an examination of an individual’s conformation. The horse with thick or loaded shoulders and wide chest is apt to roll; the one that stands with his forefeet placed wide apart, straddles; the knock-kneed one, as well as the one that toes-in, generally dishes, while the horse that toes-out, winds in. The horse with his hocks wide apart and feet close together, “screws” his hocks outwards and usually “plaits.” When the hocks are placed behind instead of under the quarters there is likely to be a dragging movement of the hind legs. It is therefore true that faulty progression is usually determinable by conformation. Defective conformation of the legs shows itself with almost unvarying regularity in its effect upon the action. In order to have straight, undeviating action a horse must flex and extend his legs during progression in a line parallel to the long axis of the body. The knock-kneed, bow-legged, or even calf-kneed horse cannot do this, and consequently experiences the ill-results of loss of time and power in progression.
Apart altogether from the question of the degree of the lightness or heaviness of the step, the manner in which the feet are placed on the ground has a great influence in determining wear and tear, and is consequently an important point to study. The horse that toes-in usually has the inside quarter of his forefeet defectively developed, which becomes more marked if he is not rationally shod. This defect of formation of the inner quarter consists in a slanting off of it from before backwards and outwards and from above downward and toward the centre of the foot, causing this quarter to assume a wedge-like form and literally to act as a wedge between the shoe and the sensitive part of the inner quarter, thus predisposing it to bruising. In addition to this, the horse that “dishes” usually brings his foot down with force on the inner quarter. This manner of planting the foot not only subjects the ligaments to undue tension, but is a fruitful source of troublesome corns.
On the other hand, a horse that toes-out is apt to come down with most force on the outside of his foot. This is a much more defective formation than the former, for it not only causes winding-in and great liability to interfere, but the planting of the foot is usually accomplished in a manner that results in the production of considerable concussion, and also subjects the ligaments to great tension, so that the legs soon begin to show the effects of wear and tear. Some horses come down with most force on their toes, causing them to stub their toes, as it is called. Such a manner of planting the foot is apt to cause stumbling and increases concussion to a marked extent. Short-pasterned, straight-shouldered, and short-gaited horses often show this defect.
Just the opposite manner of planting the foot or coming down with the heel first is not at all uncommon. This defect of action is not only likely to cause bruising of the heels, but subjects the tendons and ligaments at the lower and back portion of the forelegs to excessive strain. Ordinarily this imperfection is only observed in long-gaited horses, but some that plant their feet in a favorable manner when going at a slow pace, when forced to a faster one lengthen their stride, and show this defect, often called “pointing,” to a pronounced degree. Deep and oblique-shouldered horses with little knee action, like thoroughbreds, often go in this way, but its ill-effects are not so great as in those with a considerable amount of knee action.
“Threading” or “plaiting” are terms used to designate the swinging of the elevated foot around the one that is placed on the ground in progression. This ungraceful manner of going, which occasions a loss of power, is most clearly shown in the walk or slow trot.
