Parvovirus is a virus first identified in 1978 that spread worldwide in just two years. Over the years, the virus has mutated into two distinct strains and there is evidence of a third strain in Spain, Italy and Vietnam.

All cases of canine parvovirus or CPV come from the first two strains. It was originally thought that the virus would mutate into the feline panleukopenia, a feline parvovirus but this was found to be untrue. All species have their own parvovirus but it is not spread outside the species.

It is evident that parvovirus cannot be spread from a cat to a dog or from a bird to a cat. However, it can be spread by contact. For instance, if your cat would wander through your neighbor's yard and would pick up the virus on her feet, she can track it inside of your house and infect your dog.

My neighbour's puppy contracted parvo virus. The puppy had all of the classic dog parvo symptoms, yet my neighbour really did not know what was wrong until he thankfully took the puppy to the vet. Once he did that, treatment began immediately. Had he attempted a home remedy for puppy parvo, the puppy is not likely to have survived. After several days of intensive treatment, the puppy was free to come home.

The parvo virus works in two ways either through the intestines or through the heart. When a dog gets an intestinal infection, it is picked up by the animal through oral contact with contaminated feces. Simply put, your dog would have to come into contaminated feces from another dog.

The intestinal dog parvo symptoms occur when the virus attacks the bone marrow, rapidly dividing cells in the intestinal crypts and the lymph nodes. This allows normally occurring bacteria from the intestines to enter the blood stream to make the animal septic.

The virus can be shed in the stool for up to three weeks thus making this a very contagious disease for pets that have not been inoculated.

The cardio form of this infection is often seen in puppies that are infected from the womb or shortly after birth. It is well worth noting that the cardiac form of CPV is not as common since the mother passes immunity on to her puppies from birth. The parvo virus then attacks the heart in the infected pup and death results shortly thereafter.

Dog parvo symptoms usually present themselves within 3 to 10 days of contact. They include the following: lethargy, vomiting, fever and diarrhea. The diarrhea can cause severe dehydration and secondary infections. The dog will not usually die from the virus but from a secondary infection.

The survival rate depends upon how swiftly parvo virus is diagnosed and treatment is begun. If the virus is not caught early on, the usual treatment is given through an IV line in which fluids are pushed to re-hydrate the puppy or dog more quickly.

In addition to giving fluids, anti-nausea and antibiotic shots may be given intramuscularly as an effective parvo treatment. Given the proper care, the prognosis is good, but if care is withheld your dog will die prematurely. Most vets will strongly suggest that your pet be vaccinated against parvo about eight weeks after a puppy is weaned.
