Jaakko gets a treat and holds it in front of Talko, orders Talko to sit, then moves the treat directly over Talko's head.
Talko, with eyes on the treat, sits. Jaakko counts silently, then hands Talko the treat and praises him.
Jalko enters the room, and begins drooling. Jaakko repeats the process with Jalko, and praises the massive dog.
