Sudden Aggression in Dogs
The causes and treatments of a dog’s sudden aggressive behavior.
Note: When handling an aggressive dog, take special precautions to avoid being bitten. Even if the dog is normally quiet and loving, do not assume he will not bite you. Muzzle the dog if necessary. Use heavily padded gloves or cover the dog’s mouth with a thick towel or blanket. Herd the dog into a carrier, if possible, for transport to the nearest veterinary hospital. In extreme cases, isolate the dog in a room or pen and call animal control for assistance.
Pain: Trauma (cuts, broken bones, bruises), orthopedic disorders (arthritis, hip dysplasia, patellar luxation, back problems), ear infections, eye problems, and many others.
What to do: Take the dog to a veterinarian to diagnose the source of pain and administer treatment, if needed.
Illness: Diseases affecting mood or behavior (rabies, distemper, encephalitis, cognitive dysfunction, brain tumors, and many others).
What to do: Take the dog to a veterinarian to diagnose and treat.
Behavioral: Introduction of new family member (canine or human), maternal aggression, escalation of rough play.
