Chicken bones, especially cooked ones, are dangerous, and dogs should not be allowed to eat them. Bones can splinter and cause internal bleeding, and large pieces can break teeth and cause intestinal blockages.
According to the FDA, dogs should never be given bones of any kind because of the risk of health problems. Cooked bones are especially dangerous because they splinter, and the sharp fragments can get caught in the mouth or throat and cause irritation. They can also cause internal bleeding in the stomach and intestines of a dog. In severe cases, this can lead to peritonitis, which is a life-threatening bacterial infection that occurs when the wounds get infected.
