That the thing goes fast kaput, I can not understand. Bought the DENTAfun Rugby for my 12 year old German shepherd, because we feed barely large pieces of meat and bones, as you did this not well tolerated. A prerequisite is of course, the playful is like chewing on the dog. The natural rubber was also a reason for my purchase, the tooth-cleaning effect is very good. Dog & owner are very happy with it.
