The FDA says toss the bones from your meals...
...DON'T feed them to your dogs. They can cause broken teeth, mouth and tongue injuries and constipation. Plus, sharp bone fragments can get stuck in a dog’s esophagus or stomach, requiring surgery. And if bone fragments poke holes in a dog’s stomach or intestines, it can cause a severe abdominal bacterial infection - which will require an emergency visit to your vet, because it can kill your dog.
