  		Fig. 1. Stance phases in a rotary gallop for Dog E. (A) Beginning of trailing forelimb stance. (B) Beginning of lead forelimb stance. (C) End of trailing forelimb stance. (D) End of lead forelimb stance. Orange lines show vertical and horizontal distances between the forelimb axis of rotation and the ground contact point. (E) Beginning of trailing hindlimb stance. (F) Beginning of lead hindlimb stance. (F) End of trailing hindlimb stance. (G) End of lead hindlimb stance.

  		Fig. 2. Ground reaction force curves for Dog F plotted in body weights over the course of stance for each limb: (A) trailing forelimb, (B) lead forelimb, (C) trailing hindlimb, (D) lead hindlimb. Solid and broken lines represent the mean of the five trials from each limb and s.e.m., respectively. Lateral forces are plotted as positive values and medial forces are plotted as negative values.
