''Are bones dangerous? That question is uppermost in many people�s mind.
The answer is... yes, but only if they are cooked. Dogs are not designed to deal with cooked bones. Cooked bones are harder, more brittle and more splintery than raw bones. They are the ones most likely to be caught in the mouth, to pierce the intestines, to set like concrete in the large bowel, or stick like fish hooks into the rectum. All those events are bad news for dogs.
The long and the short of it is... don't feed cooked bones. They are unnatural and a danger to dogs.
