Canine Coronavirus: Symptoms and Treatment


The canine coronavirus it is a pathogen capable of causing a very contagious viral intestinal infection. Although all dogs can suffer from this disease, puppies are the most susceptible to infection. This is because they do not yet have an immunocompetent system, just like their digestive system. In addition, animals immunocompromised by causes such as stress are also more likely to suffer from the disease.

This disease presents a acute and self-limiting course.

How is the virus spread?

The healthy dog ​​ingests the canine coronavirus through the feces of a sick animal, being the feco-oral route. The virus has a incubation period between 24-36 hours, after which the dog begins to show symptoms.

This virus is characterized by infecting the microvilli cells of the small intestine of the animal and replicating in them. With this, the cells lose their functionality, do not absorb nutrients, which gives diarrhea and inflammation.

Therefore, dogs that are in contact with other dogs, are more likely to suffer from this disease, as well as dogs that practice coprophagy. Coprophagy is the consumption of feces or fecal material, both from other animals and their own, by dogs.

Symptoms of canine coronavirus

Coronavirus causes a disease that if caught on time, does not usually have many complications, especially in adults.

A canine coronavirus infection is generally considered a relatively mild disease with sporadic symptoms, or no symptoms at all. But if this infection occurs simultaneously with a viral canine parvovirus, or an infection caused by other enteric (intestinal) pathogens, the consequences can be much more serious. There have been some deaths reported in the most vulnerable puppies.

Occasionally an infected dog may also experience some mild respiratory problems. Puppies may have diarrhea and prolonged dehydration and are at greater risk of developing serious complications with this virus. If the virus becomes a severe enteritis (inflammation of the small intestine) in puppies, it can occasionally result in death.

Causes of Canine Coronavirus

This intestinal disease is caused by the canine coronavirus, which is closely related to the enteric feline coronavirus, an intestinal virus that affects cats. The most common source of a coronavirus infection is the exposure to feces of an infected dog. The viral filaments can remain in the body and detach in the stool until after six months.

Stress caused by excessive training, overcrowding and unhealthy conditions in general increase a dog's susceptibility to a canine coronavirus infection. In addition, the places and events where large numbers of dogs gather are the most likely places for the virus to spread.

Nucleotide supplements generate higher antibody production, something necessary to counteract viruses in the canine organism. Likewise, lymphocytes increase their power against the presence of infections.

Immunogloblulins are obtained in bovine colostrum and egg yolks. Against the canine coronavirus its action is prevent the binding of pathogens to the intestinal mucosa. This strengthens the latter by functioning as a barrier to malicious actors.

Prebiotics stimulate beneficial bacteria They strengthen the immune system. Although the body produces them, there are special supplements.

How is it treated?

Depending on each case, the veterinarian can treat them uniquely or by combining several treatments, either with antivirals, antibiotics, and with fluids If they were very dehydrated. Also, if they had diarrhea or gastrointestinal problems, they would be given prokinetic medications that are those that would help them improve the health of the digestive system.

Once the canine coronavirus has entered the body and the incubation period has expired, attacks the microvilli of the intestine (essential cells for the absorption of nutrients) and causes the loss of their functionality, which causes sudden diarrhea and inflammation of the digestive system.
