Don't buy this for a chew toy!
This is absolutely NOT a durable chew toy! It took a 12 pound maltese/poodle only 15 minutes to remove and eat a dime-size chunk off this toy. (No food was stuffed in it.) He's a pretty aggressive/obsessive chewer. Still, I'm totally disappointed in this product. He has not chewed up these two toys: Kong Classic Small Dog Toy (red), and Orbee-Tuff Ball (small, with continents). He enjoys playing with these, chews for short periods, and then stops.
