A side view of the animal as he is driven by you will give you the correct view of his front and hind action. If the action is too short, too long, too high or too low, in front or behind, the chances are you may not have to change but one end of him if you have a good eye for locating faulty action. If your horse is good and can beat his record, or go the race of his life, and scalps jogging, try a toe weight on him in front, if it does not stop him wear scalpers on him jogging and let well enough alone.
I have had to take a three and one-half ounce shoe off a colt that trotted eighths of a mile in seventeen and a quarter seconds, that was scalping jogging, and shoe him with a ten and a half ounce heel weight shoe nailed back near quarters of hind feet to prevent him from scalping at the jog, after two changes in the front shoeing.
Sideweight shoes with the weight on the outside have a different effect or result on front and hind action. An outside weight shoe on a front foot has a tendency to make the leg wing in, and an outside weight shoe on a hind foot will widen and lengthen the stride, if feet are properly prepared, so you see it widens the hind action and closes the front action. To close the action of the front leg with this sideweight, lower the front foot on the inside. To widen the action of hind leg, lower the inside of hind feet. This sideweight shoe will help a paddler that has to carry a little weight, if you will lower the inside of the foot, but it is no good for a knee knocker. The outside weight shoe has a different effect on front and hind action, has a tendency to close one and widen the other.
Sideweight shoes are good to correct the following faulty lines of action if the feet are correctly prepared for them to help the shoe, for if the foot, or feet, are not properly fixed to help the line of action this faulty fixed foot will work against the effect of the sideweight, and the results will be very unsatisfactory. Sideweight shoes are best for winging in, or paddling out, with front legs, hitching or hopping or carrying a hind leg in, out of line, or carrying a hind leg between the front legs, also good for a wheel swinging hind leg.
A trotter that is wheel swinging a hind leg, has developed a line of action that is tiresome, controlled mostly by the muscles on the outside of leg, that unbalances action at speed to a certain extent, and it looks unsightly to a good judge of gait, when coming to you or going from you. To correct this faulty line of action of wheel swinging, keep the toe of hind feet nearly as long as the front feet, and have the angle of the hind feet within two or three degrees of the same as the front feet. If the angle of front feet is fifty degrees have the angle of the hind feet about fifty-two or three degrees. Lower the outside of hind foot a full quarter of an inch or more than it will be on the inside, begin lowering the outside of hind foot at the center of toe back to outside heel, have both hind feet the same length and angle. Shoe with a sideweight shoe heaviest side of shoe on inside of foot, with heelcalks, and place a thin low calk about one inch long on inside toe of shoe in line from first to second nail holes. After the first shoeing, if line of action has not improved as it should, you must lower the outside of hind foot still more, but if you cannot lower the foot have a shoe made thicker on the inside toe and thinner on the outside toe and quarters, with the three calks on it and there will be more of a change. This change can be made in the first shoeing if you have enough of foot to change, but it is best for the horse and owner not to make too radical a change too quickly. It is best to do it in two or three shoeings, especially on a horse that has a lot of speed. Slow going horses can stand more of a radical change than fast ones.
