I get soup bones at the grocery store. They do not splinter but are hard as a rock. After our beagle removes the little bit of meat on the face of the bone and any inside meat residue, I spoon out all marrow and fill it with pumpkin, freeze it and give to him as a nightly treat. He cleans them out and knows on the bone itself. We have about 5 of them and when they have been filled 4 times I toss them and then get a new bone at the store to replace it. No problems at all.
