For tough chewers
This is great for my large puppy. It has taken a beating, and I trim off any hanging or loose pieces of rubber. It has survived the test of time.

We call it the brick.
Great chew toy. Not really made for playing fetch. It’s large and very heavy. Good construction.

Indestructible but hard to get treats out
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.
