Canine Parvovirus is a high-severity gastrointestinal condition that can affect dogs of all ages and breeds. Canine parvovirus is a highly contagious viral disease causing severe haemorrhagic gastroenteritis and immunosuppression, particularly dangerous in unvaccinated puppies. The virus is resistant to most disinfectants and can persist in the environment for months. It is documented across 1 breed, though prevalence and severity can differ significantly between them. It typically becomes apparent at 6 weeks - 6 months primarily. Early signs to watch for include severe bloody diarrhoea, profuse vomiting, lethargy, and fever then hypothermia. When treatment is required, costs are estimated at £1,500-£5,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
