We just received the new Tizzi mini size. The shape of this toy is great: the ball to bounce and the legs to grab onto and carry. However this mini size is still too heavy and big for my Chihuahuas. I would say it is the perfect size for a Beagle, maybe even a Shitzu. But my little 6 pounders had a hard time with this one and immediately lost interest. We will donate it so some other dog can enjoy.
