Front/Rear view
- The horse should move straight toward and away from you. Observe
whether the horse toes-in or toes-out as it walks. In example A, a
horse who's legs and feet are aligned properly will stride straight
ahead. In example B, a horse who toes out will have a tendency to
"wing in," increasing the likelihood that the swinging leg will
strike the supporting leg during the stride. In example C, a horse
who toes in has a tendency to "wing out" or "paddle, increasing
stress on the outside of the limbs.
Side view
- Check for the overstep, meaning do the hind feet reach beyond the
front hoof prints? Observe the horse's head. Be certain it does not
bob unusually when walking, as this may indicate soreness or
lameness.
Walk
- Look for a smooth, long stride. Avoid yearlings that walk "wide"
in front
