PupPod was designed for dogs to play one at a time, but as long as there is no food aggression, there is no reason dogs can’t play together. One benefit of flinging rewards is that they will scatter as opposed to going directly in one bowl. In our observations, when food rewards scatter there is less likelihood of food aggression.
We recommend letting dogs play PupPod on their own if they are food aggressive or show signs of resource guarding.
