How does a Promise Collar/Gentle Leader help in controlling a dog?

A Promise Collar or a Gentle Leader is an effective training tool that assists in controlling a dog's movement by applying pressure to the side of the head. When fitted correctly, this type of collar allows the handler to redirect the dog's attention and guide them more easily without causing harm or discomfort. The design of the collar allows for a gentle, consistent pressure, which can lead to better compliance from the dog, especially during walks or when encountering distractions.

This method works by influencing the dog’s head rather than pulling on the neck, which can be harmful and uncomfortable. By securing around the muzzle and the back of the head, it gently steers the dog in the direction the handler wishes, thus improving control and making training sessions more effective without excessive force. It promotes a more positive training experience and can help reduce behaviors like pulling or lunging on the leash.
