In puppies, hepatitis is brought on by poisoning or infectious diseases such as infectious canine hepatitis. The liver becomes congested and it increases in size. Hepatitis can induce irreversible and lethal cirrhotic states. Symptoms include episodes of diarrhea with loose stools, followed by constipation. The abdomen is painful and the dog is exhausted.
Acute hepatic insufficiency is characterized by disorders of the digestive and nervous systems. Its etiology is varied: infections, toxins, medicines, metabolism and trauma. Urgent treatment is required given the sometimes lethal repercussions on the body.
Chronic hepatic insufficiency evolves more slowly, but in a manner that is just as dangerous. It causes weight loss, decline in overall health and digestive disorders. A veterinarian must run complementary tests in order to determine the cause.
