What do know about Parvo?

Almost every mammal species (including humans) seems to have its own Parvovirus. The Canine Parvovirus is highly contagious, can live in the environment for years, and can cause life-threatening issues.

While parvoviruses have been around for a very long time, the Canine parvovirus is a relative newcomer.  However, it has already mutated several times and each time seems even more detrimental to our pets.

  • 1967:  The original Canine Parvovirus (CPV-1) was discovered
  • 1978: A new mutation, CPV-2 appeared in the U.S.

Because CPV-2 was (and is) potentially spread in gigantic numbers by infected animals, and because this virus  is extremely hardy, and is considered to be ubiquitous, which in this case means “present in EVERY ENVIRONMENT unless regular disinfection is applied.”

No dog had any sort of immunity against CPV-2 and the epidemic was disastrous

  • 1978: A second mutation, CPV-2a, was identified, and it seemed to be even more aggressive
  • 2000:  A new particularly virulent strain of parvovirus, CPV-2c, was discovered and is able to infect cats.

Outbreaks of canine parvovirus associated with CPV-2c in the United States were confirmed in 2006 and 2007 and most recently in New Jersey.

Parvo 2c is a highly virulent strain of the parvo virus that is extremely fatal in puppies and adult dogs. This strain of parvo attacks the circulatory organs approximately 24 hours before attacking the gastrointestinal tract. Therefore, by the time a dog is presented for lethargy, vomiting, and diarrhea it is generally too late.

    Shirlee,We are sorry to hear about your Yorkie.As you may have gathered, we are not breievels in vaccines, so even if one did exist, we wouldn’t recommend it.We hear about dogs coming down with full Parvo within days or even hours of being vaccinated on a daily basis they aren’t that effective, and they often cause the very disease they’re meant to prevent.On top of all that, they will weaken your dog’s immune system, causing issues such as chronic inflammation, and even cancer.

    I just bought a new puppy on June 28th, On July 4th monnrig I noticed he wouldn’t eat, and he wasn’t active at all. Around noon he pooped a mucusy brownish yellowish colored poop with about 10 tapeworms in it. So I gave him a wormer. two hours later he pooped same color poop, with hundreds of worms coming out. Then he played and was acting normal. I planed to take him to my vet in the monnrig, but with in a couple of hours he was down again, so I took him to an emergency vet. They did the parvo snap test, it came up positive. I told them he just got vaccinated a few days ago, could that have gave us a false reading or could he be reacting from the vaccine. They said no. Two days later he wants to play a little, he drinks, but still wont eat but maybe a few bites of rice. But he hasn’t pooped since 5:00 July 4th. And he never has vomited. So I called the vet that I took him to yesterday, and asked if he could have been misdiagnosed, cause I don’t smell a foul odor coming from him, & he’s not having bowel movements, and his temp has been normal the whole time. From the 4th to now. They said that the snap test is never wrong. I would just like to have someone’s opinion on it.
