Parvoviral enteritis is a severe, sometimes fatal viral infection of the intestinal tract in dogs and cats. Common clinical signs include vomiting, diarrhea, appetite loss, dehydration, and depression. Treatment include fluid hydration, antibiotics, anti-vomiting medication and nursing care until the infection runs its course.

The Parvo virus can live 7-10 years in a yard where an infected pet defecated. Puppies with parvo usually die if left untreated. New vaccinations are up to 98% protective from this common disease. Vaccinations should be boosted every 3-4 weeks from age 8 weeks till 16 weeks.
