Infectious Canine Hepatitis

Infectious canine hepatitis (ICH), also known as Rubarth’s disease, is a viral disease affecting dogs. It is caused by the canine adenovirus type 1 (CAV-1) and primarily targets the liver, kidneys, spleen, and lungs. This condition is highly contagious and can spread rapidly in unvaccinated dog populations. While vaccination has reduced its prevalence in many areas, sporadic cases may still occur, especially among young and unvaccinated dogs. The severity of ICH can range from mild to fatal.

The primary cause of ICH is infection with CAV-1. This virus spreads through direct contact with infected animals or their bodily fluids. Dogs can catch the virus by interacting with infected peers or by touching contaminated surfaces, such as food bowls or bedding.

Secondary causes of ICH include exposure to contaminated environments. The virus can survive on objects or in water sources that have been in contact with infected dogs. This makes it important to maintain clean living spaces for your pets.

Other causes involve indirect transmission. Insects can act as vectors, spreading the virus from one dog to another. The virus can also be present in the feces, urine, or saliva of infected animals, leading to further spread if proper hygiene is not practiced.

Symptoms of ICH can vary, but primary symptoms include fever, lethargy, loss of appetite, and abdominal pain. These are often the first signs that a dog may be suffering from ICH.

Secondary symptoms may appear as the disease progresses. These can include vomiting, diarrhea, jaundice, and swollen lymph nodes. Such symptoms indicate a more severe infection and require immediate veterinary attention.

Other symptoms of ICH can affect different parts of the body. Dogs may experience coughing or corneal edema, which causes cloudy eyes. Bleeding disorders can also occur, complicating the condition further.

Diagnosis of ICH is typically based on clinical signs and a dog’s exposure history. Veterinarians will perform laboratory tests, including blood tests and liver function tests, to confirm the virus. PCR tests may also detect the virus more accurately.

During diagnosis, it is important to differentiate ICH from other conditions with similar symptoms. Leptospirosis, canine parvovirus, and canine distemper are three diseases that share overlapping symptoms with ICH, making correct diagnosis essential.

Veterinarians rely on physical examinations and diagnostic imaging to rule out these conditions. By observing clinical signs and performing specific tests, they can determine the correct treatment path for each individual dog.

Treatment for ICH primarily involves supportive care. Veterinarians may administer intravenous fluids to maintain hydration and provide medications to control symptoms such as vomiting and pain. In severe cases, blood transfusions may be necessary.

Medications are used to manage symptoms and support recovery. By focusing on maintaining the dog’s overall well-being, supportive care helps the immune system fight off the infection more effectively.

Management of ICH involves ongoing care to support the dog’s health. Regular check-ups with a veterinarian are important to monitor liver function and prevent secondary infections. This ensures the dog remains on the path to recovery.

Incorporating lifestyle changes can help manage the condition. Maintaining a clean environment and ensuring proper nutrition are key aspects of effective management. These steps will help prevent complications and aid in the dog’s recovery.

Preventing ICH is best achieved through vaccination. The canine adenovirus type 2 vaccine provides cross-protection against ICH, making it an effective preventive measure. Regular vaccinations are important to maintaining a dog’s immunity.

Diet and lifestyle also play roles in prevention. Providing a balanced diet and a clean environment reduces the risk of exposure to the virus. These measures support overall health and lower the chances of infection.
