I had seen this happen to Dental Chewing Donut on Amazon and I thought "not for this price? Why!". Since time immemorial, this ring out of the top-3 of the favorite toys of our bitch (Goldie mix) is here to stay! She got him with 3.5 months and lived through the entire dentition with it. Am also amazed at how well the ring has held! Strong buy recommendation for puppies of medium to large breeds !!
