No. You have total control of how long your dog plays. You can start and stop the game from the anywhere using the PupPod mobile app.
If you feed normal meals with PupPod, your dog is getting the same calories per meal, but way more exercise. Dogs can walk up to a mile indoors at each meal by spreading the feeder and toy apart in a living room or hallway. You can even put the toy and feeder at opposite ends of a staircase to create a doggie Stairmaster.
For picky eaters, try shaking kibble in a bag with some treats to make the kibble more exciting and a few treats being dispensed will sometimes get a picky eater in eating mode.
