In the late 1970s, a previously unknown rapid-onset, deadly virus began attacking canine digestive systems with great fury, often killing
   puppies in 48 hours. Spread through contact with infected feces, the long-lived virus attacked rapidly reproducing cells such as those
 lining the gastrointestinal tract, bone marrow, lymph nodes, and heart. Researchers identified the disease as a canine parvovirus, CPV-2,
   perhaps a mutation of feline panleukopenia or a parvovirus that affects wildlife. CPV-2 also infects coyotes and other canids. Canine
 parvovirus survives in the environment for five months or more and clings to shoes, floors, beds, and other surfaces where it can infect
   the next unprotected puppy to enter the house. It is resistant to most household cleansers but can be killed by bleach. Parvovirus can
  decimate a litter, a kennel, a shelter, a pet store once it gets hold. Kennels that experience the disease often close their doors until they
                                           bleach every surface, towel, and dog bed.
                                              Parvovirus symptoms and treatment
 Parvovirus incubates for seven to 14 days. Initial signs of illness are lethargy, loss of appetite, and vomiting, followed within 24 hours by
   high fever (up to 106 degrees) and profuse, often bloody diarrhea. The dog's abdomen is tucked up and he appears to be in extreme
  pain. Some puppies show only the first stage of depression and abdominal pain, then go into shock and die. Parvovirus can also attack
  the rapidly-growing myocardial (muscle) cells of the heart in puppies born to a bitch who is not vaccinated against the disease. Those
  puppies that survive this form of the disease often have heart problems and die young. There are several available tests to determine if
   parvovirus is the disease-causing agent, but treatment with fluids and antibiotics should commence while waiting for the test results.
 Puppies with bloody diarrhea are in danger from loss of fluids and electrolytes; they must be rehydrated and given antibiotics to prevent
                                     secondary infections such as pneumonia and septicemia.
  Food and water should be withheld until the puppy's system begins to overcome the disease. Small amounts of a bland diet of cottage
                  cheese and rice or a prescription diet can be offered once the diarrhea and vomiting have subsided.
                                                    Parvovirus Prevention
   As with distemper, parvovirus is best prevented by vaccination. However, because there can be a gap between the gradual decline in
   residual immunity from mother's milk and the pup's ability to respond to the vaccination, some vaccinated puppies may still get the
 disease. Therefore, cleanliness of the kennel facilities is imperative, especially in kennels with lots of litters and shelters or pet stores that
  constantly receive new dogs. Kennel runs and puppy cages should be cleaned of organic matter and then bleached before new animals
    are brought in. Adjacent runs should be bleached if they are contaminated by flowing water during the hosing. Although it is not as
  serious in adults as in puppies, parvovirus can attack adult dogs. Therefore booster vaccinations are also recommended, although they
                  may not be necessary every year for pet dogs not exposed to unvaccinated animals or their feces.
 !!!We have never had a case of Parvo on the yard. Keep your dogs vaccinated, keep new dogs isolated until you make sure they are free
                    of diseases, keep your yard and kennels sanitized with bleach and keep people off your yard!!
