A fever, cough, and sore throat are the first signs of infectious canine hepatitis. The viral infection spreads to the liver, kidneys, and eyes of the dog. A low white blood cell count is often caused by infectious canine hepatitis.

A dog that has acquired a hepatitis infection may develop a bluish tint to its corneas. The eyes may appear cloudy and may become sensitive to light. Dogs may experience vomiting, diarrhea, loss of appetite, abdominal pain, and seizures.

Infectious canine hepatitis can cause bleeding problems. The dog may have nosebleeds or bleeding gums. Some dogs with this disease develop swelling of the head, neck, and trunk and hematomas which are collections of blood under the skin.

Typical veterinary care for dogs infected with infectious canine hepatitis includes an antibiotics and intravenous fluids as supportive care. There is no medication to specifically treat infectious canine hepatitis. Dogs may need blood transfusions as part of treatment for severe cases.
