Canine parvovirus causes severe haemorrhagic gastroenteritis with high mortality in unvaccinated dogs. Vaccination prevents this entirely preventable welfare catastrophe.
Parvovirus causes extreme suffering. Affected puppies experience violent vomiting, profuse haemorrhagic diarrhoea, severe abdominal pain, and the systemic sepsis of bacterial translocation through a compromised gut wall. The distress is intense and the disease course rapid — untreated puppies typically die within 2-3 days. The welfare catastrophe is entirely preventable: effective, inexpensive vaccination protects comprehensively. The welfare failure occurs in communities with poor vaccination access, in rescue organisations that inadvertently expose unvaccinated dogs, and among owners who delay or skip vaccination. Ensuring access to affordable vaccination for all dogs — including community and shelter animals — is a high-impact welfare intervention.
