Canine parvovirus causes severe haemorrhagic gastroenteritis with high mortality in unvaccinated dogs, particularly puppies, representing a preventable welfare emergency across under-vaccinated populations.
Parvovirus causes intense suffering — profuse haemorrhagic diarrhoea, severe nausea, abdominal pain, and the systemic effects of septic shock in a matter of days. Affected puppies deteriorate rapidly and die in extreme distress without aggressive intervention. Even with hospitalisation, the illness is painful and protracted; affected animals typically require 5-7 days of intensive care. The preventable nature of parvovirus disease makes it particularly heartbreaking — it is almost entirely eliminated in populations with adequate vaccination coverage. In communities and countries with low vaccination rates — often due to cost and access — parvovirus remains endemic, causing enormous preventable suffering.
