Clicker training requires a marker signal. This marker is usually a click from a handheld clicker or a tongue click. The marker signal tells the horse that what he is doing right now is what you wanted and he will be getting reinforcement soon. The signal creates a bridge between the behavior and reinforcement. It can be very hard to feed at the exact right moment when the behavior you want is happening and that is where the marker signal comes into play. I’ll talk about how to pick out a good marker signal for your horse and how to start clicker training with a fearful horse.
