Canine parvovirus causes severe gastrointestinal disease with high mortality in unvaccinated puppies and dogs, and is entirely preventable through widely available vaccination.
Parvo causes extreme suffering: profuse, bloody diarrhoea, severe vomiting, intense weakness, and pain throughout the disease course. Puppies that die from parvo typically suffer for days before death despite intensive treatment. The disease is entirely preventable through vaccination that is safe, highly effective, and available globally. Failure to vaccinate is the sole cause of parvovirus suffering in dogs — making vaccination a welfare responsibility that protects individual dogs and reduces outbreak risk for their communities.
