Query: Dog not interested. Not functional

The ball is not designed correctly. The treats do get stuck up there really well...so well in fact I had difficulty trying to get them out. After my dog gave up I wanted to get the treats out so they wouldn't be stale. It took me forever to shake out the kibble. It would be better if the ball screwed and unscrewed together.
