At first glance, the Gnawt-a-Cone might look like a Kong-shaped rubber feeder toy, however, due to the pattern in the material, when this toy is picked up and dropped (my dog's favorite way to get things out of it), it bounces completely unpredictably! Keep my dog entertained for much longer. Good quality material, has held up really well to lots of chewing and freezing with peanut butter and soggy kibble. It's a great size for my lab, but might be too small for a massive breed dog.
