Adenovirus and adenovirus infection in dogs: symptoms and treatment

A special group of infections found in dogs is called adenovirus infections. It combines infectious hepatitis and adenovirus, which are similar in symptoms, progression and treatment.

Adenovirus infection and adenoviruses are common diseases, as veterinarians, experienced breeders, and dog trainers are familiar with. However, dog owners who have never encountered this problem before often don't know the symptoms and signs of these viral diseases or the treatment they require. To recognize these infectious diseases early and help your pet as soon as possible, it's worth learning more about them.

Routes of infection

Most often, the virus is transmitted through prolonged contact between a healthy dog and an infected dog, but if the animal is weakened or ill, even brief contact is sufficient. Puppies, who lack a strong immune system, are even more susceptible to the disease, so it's important to monitor their contact with others.

There are several ways of becoming infected with adenovirus and adenovirus infection:

by airborne droplets;
through the mucous membranes;
through scratches, wounds and other skin damage;
with food or water.

The main difficulty is that transmission of the virus occurs not only after contact with a sick dog, but also with a carrier animal, that is, one that does not show obvious signs of adenovirus disease or adenovirus infection.

During the incubation period, both forms also exhibit a high degree of contagiousness.

Symptoms of infectious hepatitis

Symptoms can vary in severity, depending on the dog's immune status and the severity of the condition.

The forms are as follows:

Hyperacute. Extremely severe, with damage to multiple parts of the brain and circulatory system, and fever. Death occurs within 2-3 hours after the first symptoms appear.
Acute. Accompanied by dyspeptic symptoms such as vomiting and diarrhea, refusal to eatTemperature may rise, the liver may enlarge, and abdominal pain may develop. The animal may become lethargic. The main danger of acute adenovirus infection is damage to the circulatory system, which can cause hemorrhages, as well as inflammation of the lymph nodes and disruption of the coagulation process. A rare complication is inflammation of the meninges, which leads to the rapid death of the pet. Pregnant dogs with the acute form may miscarry spontaneously. A blue or whitish clouding of the cornea often becomes visible, causing discomfort in the animal, such as photophobia.
Subacute. Most often, it occurs as an exacerbation, accompanied by tonsillitis, diarrhea and vomiting, abdominal pain, and liver enlargement. Appetite may decrease, and lethargy may develop.
Chronic. Accompanied by minor digestive upsets, loss of appetite, and a short-term rise in temperature.

The development and worsening of symptoms in acute forms occurs rapidly, especially in weakened pets, so the time to seek veterinary care should be minimized.

In a quarter of cases of adenovirus infection, symptoms are almost unnoticeable, as liver cells successfully fight the disease even without treatment. In this case, full recovery is observed within three weeks of the onset of symptoms.

Treatment of infectious hepatitis

Before choosing a course of treatment for adenovirus infection, your veterinarian will prescribe diagnostic tests, as the symptoms of this disease are similar to many other canine illnesses. The key to diagnosis is determining the extent of liver damage by the virus. For this purpose, the following tests are prescribed:

blood biochemistry tests;
determination of antibodies to the virus;
coagulation index and erythrocyte sedimentation rate;
liver x-ray;
Ultrasound of the liver;
virus culture (bacterial analysis).

Based on the materials received, the specialist prescribes treatment, which can be carried out on an outpatient basis for mild cases or in a hospital for severe cases.

To achieve rapid results, treatment of adenovirus infection includes the following areas:

medications to relieve symptoms;
therapy to improve immune status;
hepatoprotectors for liver protection and restoration;
digestive enzymes to improve digestive function;
medications to suppress the virus.

Herbal teas containing corn silk, sage, chamomile, and other herbs complement adenovirus therapy. A therapeutic diet that is gentle on the liver and the entire digestive system is crucial during treatment. This involves completely eliminating fats and emphasizing boiled meat and specially formulated foods. During adenovirus infection, food should be given frequently, but in minimal doses.

Symptoms of adenovirus

This pathology rarely leads to irreversible consequences for the dog, but for puppies with congenital anomalies of the respiratory system, adenovirus poses a greater danger.

Adenovirus differs in its symptoms due to the fact that its main manifestations are related to catarrhal phenomena:

attacks of prolonged coughing without clearing the phlegm, which eventually turn into belching or hiccups; sometimes vomiting is possible from a strong cough;
nasal discharge and sneezing;
wheezing in the lungs during inhalation;
redness or swelling of the mucous membrane of the throat and enlargement of the tonsils, which makes swallowing difficult;
redness of the conjunctiva.

Body temperature in adenovirus cases remains normal in most cases, but a slight increase is occasionally possible. The virus infects the lymph nodes, which become enlarged and painful.

The dog experiences loss of appetite and weight loss due to difficulty swallowing and pain while eating. Sometimes adenovirus infection is accompanied by digestive disorders. The most severe complication is pneumonia.

Symptoms persist for an average of 10 days, after which they gradually disappear.

After recovery from adenovirus, the animal develops acquired immunity.

Treatment of adenovirus

Before prescribing treatment, a quick informative diagnosis is carried out, which includes:

enzyme immunoassay;
hemagglutination.

Adenovirus is considered detected when the antibody titer is four times higher than normal.

At the veterinarian's discretion, diagnostics may be expanded.

The following measures are taken for treatment:

intravenous injections and oral sorbents to remove toxins;
measures aimed at eliminating symptoms (rinsing eyes and nose with disinfectant solutions);
use of immunomodulators;
taking antihistamines;
mucolytic, bronchodilator and antitussive agents to relieve respiratory syndrome;
antibiotic therapy, the duration of which is determined by the veterinarian depending on the presence of complications;
vitamin therapy.

During treatment, your pet should be kept in a quiet room where it won't become overcooled. The veterinarian will prescribe a special diet based on easily digestible foods.
