Because the PupPod Rocker does not have food in it, we almost never see dogs try to destroy the toy
once they learn that the toy is the mechanism for earning rewards. Most dogs try to destroy plastic puzzle games because they smell like food, so once the food is gone, their reward is to destroy the toy. But since PupPod just smells like plastics and electronics, they have very little to no incentive to destroy it.
In addition, because rewards come from the feeder, dogs are constantly being redirected to eat the rewards, so they tend not to get obsessed with the Rocker.
