All cooked bones are dangerous as they become frail during the cooking process which can lead to splintering.
Raw bones are fine, they are soft, pliable and perfectly safe. The dog simply crunches them up and swallows them.
Make sure they are meaty, all the ones I recommended are. Beef bones and the leg bones of large animals are recreactional and should not be consumed (although ok to just be chewed).
Never buy bones from pet shops, they are all cooked and incredibly dangerous, they should not be allowed to sell them.
