Parvo Virus – What to Look for
01 Dec 2009
Before we look at the symptoms of parvovirus in your dog lets take a look at what it is, what it does and how it is spread. Parvovirus is a virus first identified in’78 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.
Parvo virus cannot be spread directly from a dog to a cat or from a bird to a cat, but it can be spread by contact. For example if you cat happens to wander through your neighbor’s yard and picks up the virus on her feet, she can bring it into your home and may infect your dog that way. Unfortunately, our 8 month old puppy that we acquired from the pound recently came down with parvo virus. She had all of the classic dog parvo symptoms, yet we did not realize what was wrong. We took her to our vet and treatment was commenced immediately. After a four day stay at the veterinary hospital, Lucy was ready to come home. And although we have since found out about more natural parvo virus treatments, we were actually very pleasantly surprised by our vet bill!
The parvo virus works in one of two ways ? through the heart or the intestines. The intestinal infection is picked up by an animal through oral contact with contaminated feces. In other words, a dog has to come into contaminated feces from another dog. The intestinal dog parvo symptoms happen when the virus attacks rapidly dividing cells in the intestinal crypts, lymph nodes and bone marrow. This allows normally occurring bacteria from the intestine to enter the blood stream make the animal contagious. The virus is shed in the stool for up to three weeks making this disease very contagious to non-vaccinated pets.
The cardio form of the infection is most often seen in puppies that are infected in utero or shortly after birth. It must be noted that the cardiac form of CPV is less common since the mother usually passes immunity on to her pups from birth. The virus will attack the heart in the infected pup and result in death shortly thereafter.
Symptoms of CPV usually present within 3-10 days of contact and they include lethargy, vomiting, fever and diarrhea. The diarrhea then causes severe dehydration and secondary infections. These are the actual causes of death rather than the virus itself.
Survival rate depends on how quickly CPV is diagnosed and treatment is begun. When the case is not caught early the best treatment option is an IV through which fluids are pushed to re-hydrate the animal more quickly, in addition anti-nausea and antibiotic shots may be given intramuscular. The prognosis is good with proper care but an absolute death sentence without it. There have been a few reports that the human antiviral, Tamiflu, can be effective in treating CPV but there are no studies to substantiate this. A veterinarian will advise you to give your pet a parvo shot about eight weeks after they are weaned. With the prevalence of the virus and its ability to kill some precaution should be taken to protect your canine.
