It is a misconception that bones are essential to the canine diet for their calcium content or for tartar-removing capabilities. The truth is, if a dog is fed the proper measure of a quality dog food, he is already receiving adequate calcium — and his owner can use other dental health practices to remove tartar.
Pork bones are more prone to splintering than other types, and cooked bones more likely to splinter than raw. The splinters have the potential to pierce through an intestinal wall and pass into the abdominal cavity, which may or may not cause a hemorrhage and potentially fatal peritonitis. Even raw, undigested pork bone shards and collagen can become impacted in the intestines, causing blockages that result in blood toxicity. Over time, decreased intestinal motility causes digestive complications.
Edible hollow bones that are raw provide calcium and are suitable for grinding and applying to kibble. Raw beef bones too large to eat, such as a beef knuckle bone, provide stimulation and clean the teeth. Monitor your dog when he gnaws on a bone. Keep the pork bones out of his maw
