If a dog that has never shown any sign of aggression suddenly begins growling, snapping, or biting, it may be caused by a disease or illness.

Pain is an especially common cause of aggression in dogs.

Some possible causes of pain include arthritis, bone fractures, internal injuries, various tumors, and lacerations.
