Can dogs eat bones? No! No! No!
Problem #1: Broken Teeth
The carnassials are most likely to fracture because these are the bone-crunching teeth.
Here is a bone-chewing incident where the upper carnassial has sustained a slab fracture. Those two dark spots are exposed roots. Bacteria invade the exposed roots leading to an abscess necessitating removal of the entire tooth.
Treating a periapical abscess is to remove the entire tooth, which is difficult because there are three roots, making this to most difficult tooth to extract. The dog will be put on antibiotics and anti inflammatories.
