In the past, it was said, “Never feed a horse treats or it will start biting”. Well, that can be true if a “marker” sound is not used to announce the giving of a treat.
I always use a “kissing” sound before I give a treat. The horse hears the sound and soon makes the association that a treat is coming. The horse also then makes the association that when no “kissing” sound is heard, no special treat will appear.
