On the whole, this is a nice chew toy, but for large breeds unsuitable. Our puppy (German Bulldog, 8 months old, 50kg, shoulder height 80 cm) did not need 15 minutes. to chew the one end and where the beginning is, ... Supposed to serve employment, so that he can be the toy of the kids alone. Well, I give him three days, then the toy is probably gone again. Shame
