Now let's step in front of the horse. When looking at the horse from the front, superimpose a mental vertical line. It should travel in a straight path from the point of the shoulder, through the middle of the forearm and down the cannon bone, pastern, and foot. No angles there. Just a straight line.
Any deviations are aspects of poor leg conformation.
We also want to see the same distance between the forearms at the chest as between the two feet on the ground. If the distance is narrower at the feet, the horse is said to be base-narrow. If the reverse is true, the horse is said to be base-wide. One of the most serious front leg conformational defects is called toeing out. When looking at the horse with our straight vertical line imposed, we will observe that the toes are turned outward and the line, instead of traversing the center of the foot, will be to the inside.
