any of a group of viruses containing DNA in an icosahedral protein shell and causing disease in dogs and cattle. Causes throwing up and exploding diarea and in a 24 hour time period the animal will pass. Can be caught for up to 7 years in the soil where either cattle have been or where the animals have shat. is cureable! kinda.. either the vet will charge you a rediculous price or you can buy a liquid from a feed store called parvaid. its a 50% chance your animal may live or end up like pet cemetary.
