An apparatus and method of supplying liquid consumable substances to animals using a dispenser device, including storing a volume of viscous fluid in a storage chamber of the dispensing device, capturing a roller ball in a flanged opening at an open end of the dispensing device such that a first surface of the roller ball communicates with the storage chamber, communicating at least a portion of the stored volume to the first surface such that a quantity of the stored volume adheres to the first surface, and exposing a second surface of the roller ball to an animal's tongue such that when the animal licks the second surface, the roller ball rotates with respect to the flanged opening to deliver at least a portion of the adhered quantity to the animal as a reward for a desired exhibited behavior of the animal.
