We are on, I believe, our fourth or fifth one of these.  You may assume by that they they are not indestructible, and you would be correct.  However, in every violent "casualty," another dog has been the 'killer.'  My dog LOVES these things and treats them like they are her baby.  She carries them to bed, she licks and licks them.  The licking was the "cause of death" for at least one of them; I have another around that's still intact but looking rather haggard from being so well loved (so we have a new one as a 'spare').  She LOVES the FIVE squeakers, and it's a great soft, squishy size.  (FYI, my dog is a 7-year-old 70lb Golden Retriever female; she's typically somewhat gentle on stuffies, although she's certainly destroyed her fair share, too).  For MYYYY dog (and I know this doesn't work with all dogs), if she sees me cuddle and pet her toy for a while first before letting her play with it, she tends to not destroy it (or, at least, not as quickly).  I'm not sure if it's because it gets my scent on it or if she decides that my actions mean it's to be 'babied."  I guess I'm playing into her maternal instinct.  This has absolutely been her FAVORITE toy for the LONGEST of all, so I definitely recommend it if stuffies are at all an option for your dog.
