Dog Parvovirus Prevention and Welfare

Canine parvovirus causes severe haemorrhagic gastroenteritis and is preventable through vaccination, with significant welfare implications for unvaccinated dogs.

Key Facts

Parvovirus causes rapidly fatal haemorrhagic diarrhoea, particularly in unvaccinated puppies
The virus persists in the environment for months to years
Treatment requires intensive hospitalisation with IV fluids, antibiotics, and supportive care
Vaccination provides excellent protection from 8-10 weeks onwards
Rescue dogs from endemic regions are at high risk if unvaccinated on arrival

Welfare Considerations

Parvovirus causes one of the most severe acute welfare emergencies in companion animal medicine. Affected puppies experience bloody diarrhoea, vomiting, and circulatory collapse. Vaccination is highly effective and the welfare case for vaccinating all puppies is unambiguous. Treatment without vaccination leaves millions of dogs vulnerable to preventable suffering.

What You Can Do

Vaccinate all puppies against parvovirus starting at 8-9 weeks
Avoid unvaccinated puppies from areas with parvovirus until fully protected
Support rescue organisations ensuring imported dogs are tested and vaccinated
