Query: Too easy

This toy provided very little mental stimulation to my dog. The treat is so exposed and extremely easy to eat off, and the bone so hard and ball so heavy he wanted nothing to do with it after the treat was gone. We have a heavy chewer, but unless you have a small dog with a small light bite that takes time eating it, I just can't imagine it would be worth the price of buying their own hides to attach. I would suggest a nylabone first to make sure your dog is interested in chewing on the bone part even when there isn't treats attached.
