We have a power chewer and have had the black Kong products for a long time. I opted to try this new design however, the shape makes it difficult for our dog to reach the treat. We have stopped using it since I had to keep digging the treat out for her. : ) The black Kong shaped like a pear works much better for her. Giving this 3 stars overall because she can't really use it well.
