The chipmunk was unpacked, torn from his hands and enjoys particular popularity with our dog. However, it is silent for about half a day. I do not know if the inner life became very chewed or whether from fright. But neither the dog nor do we get squeezed out a sound. However, I would not recommend it for medium to large dogs, but because it is very delicate and is about halfway out quite unrobust acting tail. To play it is good still. Therefore 2 stars.
