This is one of the biggest myths of all time! Raw chicken bones and other species raw (non weight bearing) bones, such as rib bones and necks are fantastic for your dog. They are soft enough so that they crunch easily, the stomach acid softens them and breakdown well for the dog to digest.
COOKED chicken bones are the bad guys, (the molecular structure changes and makes them brittle), these are the ones that shatter and are like daggers.
We do grind all the RAW bones up in our dog meals to make them 100% safe.
