They claimed it was a "nondestructable" Kong Bone but I knew better. Watson is very strong at 7 months old. Every muscle in his body is strong as well as his jaws just like any other bloodhound. For example Sadie and Stella when confined to a large black metal dog crate could bend those heavy steel rods on the crate. I could not even straighten back them with pliers. So I knew no matter what the reviews were on the internet, this great looking "nondestructable" bone wasn't going to look that nice very long.
