Parvovirus can show up as sudden death due to heart damage in very young pups.
More commonly, it appears in pups from 3 to 12 months old with severe, often life-threatening diarrhea and vomiting. Young pups can dehydrate easily, and the disrupted intestinal lining leaves them open to other serious infections. Puppies are born with some immunity received from their moms. The exact time that it takes for that immunity to wear off, and for the pup to produce his own immunity, varies from puppy to puppy. That's why pups need a series of vaccinations.
