During training, Gerosky and Koons use a treat to get a dog to behave a certain way. For example, to get a dog to sit, they hold a treat just above the dog’s nose.
As the dog looks up, its body naturally sits. At the same time, the trainers use cues. Those are special words or hand movements. Once the dog sits, it gets a treat as a reward.
Gerosky explains that the dog learns that a cue means it should behave in a special way. If it does, it will get a treat.
Next, the trainers add more time between the trick and the reward. That time gets longer and longer. Soon, the dog does the trick without a reward!
