Infectious disease in dogs parvovirosis favorite animal

ParvovirosisWatch out for diarrheal diseases! Your favorite pet may have contracted what is known as parvovirosis – also known as canine plague. A study in 2009 showed that over 71% of dogs with diarrhea that were checked tested positive for parvovirus (Decaro et al., Detection of canine parvovirus type 2c by a commercially available in-house rapid test, 2009). Parvovirosis is a highly contagious viral disease, still widespread in some regions, and one of the leading infectious causes of death in dogs.

Parvovirosis is caused by different variants of the canine parvovirus (CPV 2a, 2b and 2c), a very resistant virus that can survive for weeks to months in the environment. The responsible pathogens are massed from sick animals with feces. Urine excreted: one gram of feces can infect about one million dogs. Variant 2c is now the most important, and is found in many countries – u.a. Spain, Germany and Great Britain – and often leads to life-threatening diseases. Especially puppies with insufficient protection. Unvaccinated dogs are defenceless against the merciless epidemic. Tragically, puppies, even if they have survived the acute phase, often die before they reach their third month of life as a result of inflammation of the heart muscle. Animals can die of heart failure years later due to organ damage caused by the virus. Doberman pinscher, Rottweiler and German shepherd are also amed to have an increased susceptibility (breed predisposition) to this disease.

Parvovirosis is also known as canine plague

What causes parvovirosis?

The canine parvovirus needs cells with a high division rate for its reproduction, so the pathogen likes to settle in the intestinal mucosa and bone marrow. Treatment of the viral infection itself is not possible, we can only try to relieve the symptoms such as vomiting, diarrhea, fever and dehydration in our four-legged friends. Accordingly, the prognosis remains doubtful. Infection of the bone marrow leads to a marked deficiency of white blood cells (leukopenia), with lymphocytes particularly affected. This results in a weakening of the immune system (immunosuppression), which in turn favors secondary infections with bacteria or the canine coronavirus (CCV is very similar to parvovirosis).

What are the symptoms of canine epidemic?

The severity of parvovirosis depends on several factors. Not only the age and the immune strength of our dogs influence the degree of the disease, but also the dose of infection. Good hygiene can, for example, prevent puppies from coming into contact with large amounts of the virus. Once a dog is infected, it usually takes 4 to 7 days for the disease to become acute, with sudden, severe and prolonged vomiting. Watery, often bloody diarrhea sets in shortly thereafter. The animals can have a fever of up to 41.5°C or suffer from under-temperature during the course of the disease. Due to diarrhea. Vomiting the animals are quickly dehydrated. Deaths occur mainly in young dogs as a result of blood poisoning or endotoxin shock (endotoxin shock is the most common form of septic shock).

How can my dog get infected?

Infection occurs mainly through ingestion of infected feces via contaminated feed. But it can also occur, for example, by licking fur and hands, carpets or clothes (risk: shoes soiled with feces). Other secretions or excretions play only a minor role here. Direct transmission of the virus from dog to dog is also rare.

vaccination against parvovirosis is important (core vaccination)

How to protect your pet? The most effective protection is a vaccination against all variants (CPV 2a, 2b and 2c) of the virus in puppy age. Vaccination can be used from the age of 4 weeks. Important for the development of an effective immunity is a correctly performed basic immunization. After basic immunization, dogs must receive regular booster vaccinations. If you are unsure whether your dog has the dog disease, contact your veterinarian immediately. He can also help you with further questions about parvovirosis or the vaccination of your favorite animal.
