The only kind of bones that our dogs get are marrow bones. Anything like rawhide, pig ears, or anything else can be way too dangerous. I would never chance it. They do occasionally get antlers, though.
Marrow bones and bully sticks. If you get the marrow bones, make sure you get the long ones, like 6". You can ask your butcher at your grocery store to cut them special for you. The smaller ones that are like donut rings are risky -- Daisy once got one wrapped around her lower jaw. Had to take her to the vet at midnight to get it taken off -- very expensive.
