Parvovirus Parvovirus is a serious, deadly threat to the unvaccinated dog population. The virus can survive searing heat and subzero temperatures for long periods of time, and so the virus might remain long after the feces has been removed.
Most veterinarians recommend multiple parvovirus vaccinations for the growing puppy.
Vaccinations establish protective immunity, which can reduce the risk of the disease. Once vaccinated, your dog's immunity is maintained through annual booster shots. If your dog is experiencing vomiting, severe diarrhea, depression, or loss of appetite, you should see your veterinarian as soon as possible. Specific drugs have not yet been perfected that will kill canine parvovirus, but proven treatments are available to control the complications of the disease. If you suspect that you have walked through an infected area, wipe off your shoes with one-part household bleach to 30 parts of water solution.
