I'm satisfied with this bone but my dog, Max, loses interest as soon as the treats are gone, I guess that's how it's supposed to work. He seems to have a hard time getting all of his treat out, I usually have to push it out for him. He's a 4 year old mini schnauzer, so I figured he'd enjoy playing with it more. On the other hand, it has held up well, it really is "indestructible".
