Why has exhibiting their horse so low headed it does not look natural for reiners become so popular recently?

The trend toward extremely low head carriage in reining horses — heads carried well below the point of the withers, noses sometimes approaching horizontal or below, in a posture that bears no resemblance to the natural carriage of a horse moving freely — represents the intersection of competitive incentives, training shortcuts, and evolving judging preferences in a way that has produced a look that many experienced horsemen find neither natural nor correct. The trend exists primarily because it has been rewarded. When exhibitors discovered that horses shown with extremely low head carriage were placing well at significant competitions under influential judges, the incentive to produce that head carriage regardless of whether it reflected genuine collection and relaxation became immediate and powerful. The training world responds to what wins, and when a specific visual presentation is associated with competitive success at events that matter, that presentation spreads through the competitive population quickly regardless of whether it represents correct horsemanship. The training methods most commonly used to produce the extremely low head carriage are the same methods that produce behind-the-vertical problems in other disciplines — mechanical aids that create downward pressure on the head and neck, heavy draw rein work that teaches the horse to carry his face low to escape pressure, and training philosophies that prioritize the visual position of the head over the quality of the topline and the genuine self-carriage that correct collection produces. The horse exhibited with an extremely low head has often been trained to carry that position through the relief-seeking mechanism that mechanical pressure creates — he carries his face low because low is where the pressure releases, not because he is genuinely relaxed and through in his topline. The problem from a biomechanics standpoint is that extremely low head position is incompatible with the genuine collection that the reining maneuvers require at their best. A horse whose head is below the point of the withers with his neck at or below horizontal has his poll in a position where the hindquarters cannot engage correctly and where the topline cannot round and carry through in the way that correct stops, spins, and lead changes actually require for their highest expression. The response within the reining community has included increasing discussion at the rulebook level about whether judging criteria should specifically address extreme head carriage, and some judges have begun to more actively reward the naturally collected through self-carried head position that the discipline's best historical performances exhibited.
