Some are hollow in the middle, and at $6 + that’s unacceptable. Customer service is pretty good though. Some bones seemed to be older & possibly stale as my dog had some stomach issues afterwards.
My dachshund loves them, but I’m constantly having to cut the ends off with a sawzall so she can get the marrow. Not sure how others do it.
my Boston Terrier is a big time chewer, He loves these bones and they last forever. if your dog is a big chewer then I highly recommend you purchase these.
My dog, as well as my son's are tough chewers. They love these bones and they last a lot longer than other items. Even "tough" items.
