Canine Parvovirus Disease

Keeping Britain's Pets Healthy dog parvovirus information

Severe weakness and depression

Clinical signs are usually observed 3-5 days after infection

Severe diarrhoea and immune suppression

Affected puppies and dogs experience very severe diarrhoea due to profound damage to their gut and this is commonly associated with a great deal of blood. Fluid loss and entry of bacteria into the body with a reduced ability to fight infection commonly leads to rapid deterioration and death

Anorexia and Vomiting

The dog is likely to refuse food and water and repeatedly vomit on an empty stomach –  combined with increased fluid loss this can lead to very rapid dehydration.

Severe weakness and depression

Clinical signs are usually observed 3-5 days after infection

Density of Reports

The map shows the density of confirmed cases of parvo for the past three years.

This is not necessarily an indication of what areas the disease is more prevalent in, as the data captured by these labs is likely to be a small proportion of the suspected number of dogs that might be affected by the disease.

This is, however, an indication that this disease is present in the UK and if vaccination rates drop, we are likely to see an increase in the number of dogs being affected by this dangerous disease.

How is it spread? 

The main source of infection is the faeces of infected dogs; the virus can also spread on shoes and clothing and on the coat and pads of dogs.

Prevention and Control

There is no specific treatment for canine parvovirus, so it is important to ensure that your dog is vaccinated in both puppyhood and adult life to stop the disease and reduce the chance of spreading infection. Unfortunately, canine parvovirus is very stable in the environment, so any animal which sheds the virus not only contaminates the environment, but poses a risk to other animals as well.

Some vaccines against parvovirus offer a duration of immunity of up to 3 years so that following a primary vaccination and a first annual booster most dogs should be protected for at least a full three years against parvovirus.
