Clicker training began to grow in popularity in the mid-1990s as an effective alternative to training that relied on pain, fear, and intimidation. A clicker is a small, handheld device that makes an unmistakable, distinct “click” noise used to inform our dog of the exact moment they’ve done something right. To learn more, Sarah and I went to Master Peace Dog Training in Franklin, MA for a clicker training session with the owner, Fran Masters.
