it took less than a week for my 16 lb boston terrier to chew out the bell. he plays with a lot of other toys also.
I would give this toy 5 paws except when my one boxer plays with this toy it sometimes get caught on her bottom jaw and she can't get it off. She will go right back and play with it though. My other boxer loves to chew on it. It is holding up great. I only let them play with the toy when I am home because of it getting caught on the jaw of my one dog. Great toy though!
