Where does the bit lie in the horse's mouth?

The bit lies on the bars of the horse's mouth, which refers to the area between the horse's incisors (front teeth) and molars (back teeth). The bars are essentially the gum-covered space where there are no teeth, making it a sensitive area that is ideal for the placement of the bit. This positioning helps in communication and control as the bit applies pressure on the bars when the reins are pulled, allowing the rider to direct the horse.

In contrast, the other areas mentioned—such as the gums, teeth, and lips—are not appropriate locations for the bit. The gums can be sensitive and do not provide the necessary contact for effective communication. The teeth can create discomfort and hinder the horse’s ability to respond correctly to signals from the rider. The lips are more for protection and provide mobility in eating and tasting but do not serve as a stable point for control. Hence, placing the bit on the bars facilitates proper use and control while being less invasive and more comfortable for the horse.
