Don't give a dog pork rib bones or any other type of cooked bone due to the risks of choking and digestive obstructions or lacerations. Even if the dog safely swallows the bone, it can still splinter and cause serious internal harm.
Cooked bones are more brittle than raw bones and fragment more easily. Additional risks to dogs from chewing cooked bones include broken teeth, mouth injuries, rectal bleeding, peritonitis and constipation.
Recreational bones such as beef or bison femurs are safer to chew on due to their softness, but they still require owner supervision. Although these bones provide little nutrition, the gnawing action stimulates the dog's mental faculties and improves dental health. In households with multiple dogs, it is important to separate each dog before the feeding of recreational bones.
