Cooked bones splinter into shards — they perforate or obstruct the gut and are a recurring surgical emergency. The "dogs and bones" image is wrong for cooked bones.
Never — splintering hazard exactly as in dogs.
Cooking makes bones brittle; shards injure mouth, esophagus, stomach, intestines.
Gagging, drooling, vomiting, bloody stool, abdominal pain, constipation.
If your dog swallowed cooked bone shards, call the vet — watch closely for obstruction signs.
