Walking on the right rein
Hind triple stance
In the series of illustrations shown here, the horse starts the walk on the right rein, with the horse placing the right hind leg on the ground. The horse is now standing on three limbs, the right and left hind and the left fore (Fig. 8.2).
Right diagonal double stance
The left hind leg is then lifted, leaving the horse standing on two limbs: the right hind and the left fore (Fig. 8.3).
Fore triple stance
The right foreleg is then set down, so that the horse is again standing on three legs: the right fore, left fore and right hind (Fig. 8.4).
Right lateral double stance
In Fig. 8.7 the left fore is lifted off the ground, leaving the horse standing on the right hind and right fore limbs, a position known as the right lateral double stance. Figs 8.8 and 8.9 show the skeleton and musculature, respectively, involved in the left fore lift-off. Fig. 8.10 shows the position of the right lateral double stance while Fig. 8.11 shows the skeleton and Fig. 8.12 shows the musculature.
Left diagonal double stance
The left hind leg then hits the ground so that the horse is again standing on three legs: both hind legs and the right fore. This is the hind triple stance again, but with different limbs involved compared with the first hind triple stance. Following this, the right hind lifts off. In Fig. 8.13 the right hind is lifted off the ground to leave the left hind and the right fore on the ground. Figs 8.14 and 8.15 show the skeleton and musculature involved in the right hind lift-off, while Figs 8.16–8.18 show the left diagonal double stance itself.
