Which characteristic is NOT ideal in a western pleasure horse?

In the context of western pleasure horses, an ideal horse typically demonstrates a calm, relaxed demeanor and smooth, consistent motion while being ridden. Characteristics such as a relaxed head position, a soft and consistent gait, and engaged hindquarters contribute to the overall aesthetic and performance qualities expected in this discipline.

A tense head position is contrary to the principles of western pleasure, which emphasizes relaxation and fluidity. When a horse carries its head in a tense position, it may signal anxiety or discomfort, which can detract from the overall impression of tranquility and harmony that judges look for in this discipline. Therefore, this particular characteristic is not ideal for a western pleasure horse, as it does not align with the desired traits of calmness and smoothness in movement that reflect a well-trained mount.
