Hepatitis

Do Dogs Get Hepatitis?

Do dogs get hepatitis? People obviously do. But do dogs get this disease? And how does this affect them?

Hepatitis is actually a very broad term. It will signify an inflammation of the liver, although the causes may actually differ. Since the liver is a very complex and vital organ a disease that incapacitates it will prove to be fatal. The livers primary functions are the detoxification, metabolism, the storage of glycogen and the synthesis of plasma protein. It also produces the bile that aids in digestion. The good news is, the liver is a large organ with plenty of reserves. The bad news is, since it has a large reserve, it won’t show apparent symptoms unless the liver is seriously damaged.

Although dogs do get hepatitis, it may be different in cause and effect from human hepatitis. There is what is called Infectious Canine Hepatitis. This disease is caused by a virus, and may prove to be a fatal disease in some dogs.

What is It?

This disease is caused by the CAV-1 an adenovirus. Dogs typically acquire this virus from contact, either through inhalation or ingestion of urine, eye secretions, and nasal secretions of infected dogs. This type of virus does not affect humans or other animals, only dogs.

The virus will attack the liver, eye, kidney, and blood vessel cells upon entry into the system of the dog. Fortunately, not all of these infections are fatal. Some dogs, after acquiring this virus, will manifest a cough, lethargy, loss of appetite, moodiness and low grade fevers. In some cases, they do not show any symptoms at all.

Some will develop blue eye. Blue eye is a bluish discoloration of the cornea of the pets eye. Dogs that go through these become immune to re-infection from the disease. This will usually be the case in healthy, mature dogs with a healthy immune system.

However, there are some dogs especially puppies that will become very ill due to the virus. These dogs will develop internal bleeding, liver disease, tonsillitis, and general inflammation of the eyes and mouth. If left untreated, this condition could quickly deteriorate to shock and death.

The virus is also known to attack the dog’s spinal cord and brain.

After infection the virus will take about five days to a week before manifesting openly. By this time the dog will be secreting the virus through its stool, urine, saliva, and nasal secretions. In two weeks time, the dog either succumbs to the illness or develops chronic hepatitis coupled with cirrhosis of the liver. This will seriously impair the dog’s capacity for converting glucose, and absorbing toxins.

This condition will reduce the liver’s capability to perform functions necessary for life. These functions include filtering harmful and toxic elements from the blood, storing blood sugar for conversion into usable energy, and creating many proteins that are necessary in the system.

Unfortunately, there is no way to destroy the virus after it has entered the dog’s system. Veterinarians will treat the disease by good supportive therapy intravenous fluids, good diet, rest, medicines to lighten the liver’s workload, and good care all aimed to strengthen the dog’s ability to recuperate. They will also give antibiotics to treat secondary infections.

There is a vaccine for this disease. It is a routine part of a puppy’s vaccination plan. And partly due to its efficiency, the cases of canine hepatitis in the United States are low. Therefore, the best way to keep your dogs free from this disease is a proper vaccination plan, and prompt and periodic visits with the veterinarian.

Canine hepatitis can prove to be a troublesome disease that, if unattended, will surely result in a dog’s death. With proper information about this disease dog owners will be able to take preemptive steps to assure themselves that their pets are safe from this debilitating diseases.

Chronic Active Hepatitis:

As opposed to the previous disease, this form of hepatitis is harder to treat and the prognoses are not very promising. This usually occurs in dogs of advanced age. The disease is caused by other factors such as toxins and molds in the dog’s diet. Infectious Canine Hepatitis can also cause this.

The symptoms of this disease are hard to pinpoint, but generally they will include lethargy, diarrhea, loss of appetite, swollen abdomen, jaundice (or yellowing eyes, gums, and skin). This disease could advance into the nervous system and render the dog blind. Seizures, coma and death usually follow.

To avoid this disease, good health habits including a good diet that emphasizes foods screened for toxins and molds should be exercised.
