Parvoviruses

Parvoviruses are a serious threat to your dog's health. They can lead to severe gastrointestinal illness, blood loss and even death. In this blog post you will learn what parvoviruses are, how they are transmitted, how you can recognize and treat them and how you can protect your dog from them.

What are parvoviruses?

Parvoviruses are small viruses that infect and destroy the cells of your dog's small intestine. This causes inflammation of the intestinal mucosa, which leads to diarrhea, vomiting, loss of appetite and fever. The viruses can also damage your dog's bone marrow and heart.

Parvoviruses are very contagious and can be transmitted through direct contact with infected dogs or through their feces, urine, saliva or vomit. The viruses can also stick to shoes, clothing, food bowls or toys and thus infect other dogs. Parvoviruses are very resistant and can survive in the environment for months.

How do I recognize parvoviruses in my dog?

The symptoms of a parvovirus infection usually appear within 3 to 10 days of infection. The most common signs are

  • Bloody diarrhea
  • vomiting
  • Loss of appetite
  • lethargy
  • fever
  • dehydration
  • weight loss
  • Weakness

If you notice one or more of these symptoms in your dog, you should see a vet immediately. A parvovirus infection can be life-threatening and requires intensive treatment.

How is parvovirus treated in my dog?

There is no specific treatment for parvovirus. Treatment is aimed at relieving symptoms and stabilizing the dog. This includes:

  • Fluid and electrolyte therapy to combat dehydration
  • Antibiotics to prevent or treat secondary bacterial infections
  • Painkillers to relieve abdominal pain
  • Antiemetics to reduce vomiting
  • Immunostimulants to strengthen the immune system

Treatment can take several days to weeks and usually requires hospitalization in a veterinary clinic. The chances of survival of a dog with parvovirus depend on various factors such as age, health status, immune status and severity of the infection. In general, the mortality rate is around 10 to 30 percent.

How can I protect my dog from parvovirus?

The best way to protect your dog from parvovirus is vaccination. Vaccination should start when your dog is a puppy and be given regularly. The exact vaccination intervals depend on your vet's recommendation.

In addition to vaccination, you should also take the following precautions:

  • Avoid your dog's contact with sick or unvaccinated dogs
  • Clean and disinfect all objects that have come into contact with infected dogs
  • Wash your hands thoroughly after handling dogs
  • Keep your dog away from places where many dogs come together, such as parks, animal shelters or kennels

Parvoviruses are a serious danger for your dog. But with the right prevention and treatment, you can give him a long and healthy life.
