Maybe saddle rack. There was no head nod. Hunter racks at speed, but he has a long lean neck. Tosca's neck is short and thick, at least comparatively. So yes, her head and neck were a little up, at least as compared to the Arab Bev was riding at the same time, but she really carries herself in a very natural relaxed way. No one has attempted any "gait training" with her, just a nice basic job of horse starting as we would a horse of any breed.
