Canine parvovirus was one of the first major viruses that was recorded to have caused many deaths in dogs. It is spread through direct contact with infected dogs or its feces. The virus can survive in an environment for many months so it is important to disinfect your house and throw away any bedding or towels used by the infected dog before introducing a new dog.

Parvovirus is most dangerous because it can infect any dog at any age but is often fatal in young dogs causing vomiting, fever, severe and often bloody diarrhoea.

Treatment is usually done by administering intravenous fluid and antibiotics. Hospitalisation is required, and while some dogs do recover it is both time consuming and an expensive process.
