What is an essential cue for a horse to stop moving?

Gently pulling back on the reins is an essential cue for a horse to stop moving because it directly communicates to the horse that a halt is desired in a manner that is clear and considerate. This action encourages the horse to respond to the cue without causing panic or discomfort, fostering a better connection between the horse and rider. It serves as a natural signal that the horse has been trained to recognize as a request to reduce its speed or come to a stop.

Using a calming voice or applying pressure with the legs can be complementary cues but are not the primary signals for stopping. A sharp pull on the reins can create a negative reaction, such as resistance or fear, which can compromise the horse’s training and the rider's ability to maintain control. Thus, a gentle pull back is both effective and promotes a harmonious riding relationship.
