No chicken or fish bones. Never feed your dog bones from chicken or fish - or similar items like shrimp tails - because these can get stuck in the throat - necessitating an emergency trip to the nearest vet - and often have sharp edges that can slice into the oesophagus. While bones are indeed rich in calcium, an essential ingredients in your dog's diet, it is far safer to supply this by giving your dog the occasional bowl of milk or some calcium tablets.
