We had noticed a chicken carcass about 4' offshore in the water that fish were picking at, and later a puppy came to eat. We were having our lunch nearby when there was a splash. A croc had grabbed the carcass and the puppy had backed up about 6-8' with its hairs on end. We watched over the course of 12 minutes as it finished its meal. Never seemed to show any interest in the small fish or the puppy.
