Wall-E goes through phases with his ETB. He played with it a week straight when I first got it... then he got bored with it. Then I tried filling it with a different treat every week (Wellness WellBites) and some kibble... then he got more interested in it. One day he'll play with it, another day he won't touch it. Most of the time though, we use it to play fetch and then when he gets tired, he'll lay on the floor and chew on the ball to get the treats out.
