Canine parvovirus is highly infectious and dangerous to dogs. Preventing parvo in dogs is far easier than treating a dog infected with parvo.
Because Canine Parvovirus can be found anywhere infected dogs have visited, the cornerstone to protecting your dog from the parvovirus is vaccination. Since the development of the parvo vaccine, the incidence of infection has been greatly reduced. A single modified live vaccine can confer protection within three to five days. Although parvoviruses continue to evolve, vaccination appears to confer reliable protection against all known strains.
