Parvovirus In Dogs - How To Prevent This Deadly Disease

If you have a dog then you've probably heard of parvovirus. But you may not know why it is such a dreaded disease or why some people take such precautions against it. Here's some information about parvovirus in dogs and how to prevent it.

A Short History of the Disease

Parvovirus first appeared in the 1970s, so it is a relatively new virus strain. It was only recognized in 1978 but it had spread worldwide in just two years because dogs had no immunity to it and there was no vaccination at that time. The mortality rate amongst unvaccinated dogs who had come into contact with the disease was over 90 percent. It is a highly deadly disease and, without a vaccine at that time, countless dogs died from it.

Following the development of a vaccine, along with the gradual development of some natural immunity passed on by some of the surviving dogs, the mortality rates began to come down. However, the disease is still extremely deadly to puppies and unvaccinated adult dogs.

Immunising Puppies Against Parvovirus

When puppies are born they receive the same immunity to diseases their mothers have. However, this immunity only lasts a short time - a few weeks in fact. It begins to wear off at different times for different puppies in the litter. If the mother has been vaccinated for parvovirus then the puppies will be born with some immunity to the disease. Some puppies may have an immunity for 5-6 weeks, others for 8-9 weeks and some may be immune for a little longer. This depends on how many antibodies the puppies absorbed in their mother's milk in the first few hours after birth.

This is why it's necessary to give puppies a series of shots with parvovirus vaccine. If the puppy is still immune to parvovirus at 6 weeks and gets the vaccine, this means that the vaccine is ineffective. But you have no way of knowing this. So, have the vaccination given again at 9 weeks. This time the puppy's immunity has worn off so the vaccine is effective in protecting the puppy. The puppy is now properly immunized.

Other Ways You Can Protect Your Puppy

Even after your puppy is immunised against parvovirus and other diseases you should be careful for several weeks. Do not take a young puppy to a pet supply store where unvaccinated dogs may wander. It's too easy for a puppy to pick up parvovirus or another disease in such a place. You also shouldn't take a very young puppy to a dog park or other places where dogs congregate for the same reason. It is possible for vaccinated dogs and puppies to occasionally get parvovirus in spite of their vaccinations so it's wise to be cautious.

Parvovirus and Animal Shelters

Parvovirus is often passed around animal shelters so you should be very careful about any puppy or dog you adopt from a shelter. If you have other dogs at home it's a good idea to try to quarantine your new puppy for the first few days so the disease won't pass along a disease to other dogs. This may not be possible but it is a good idea.

Parvovirus and Breeders

There are a few other ways to prevent parvovirus. Breeders will take special precautions when they have a litter of puppies to prevent parvovirus from being brought in contact with the puppies. They may refuse to allow visitors to see the puppies for the first few weeks to prevent the spread of disease. Some breeders insist that any visitors not have contact with other dogs or puppies prior to a visit. They may also insist that you step in bleach to stop you from tracking parvovirus germs in the house. Or they may ask you to bring a separate set of clothing to wear to come in the house and see puppies. These are all precautions so you will not pass parvovirus to their puppies.

Parvovirus is deadly so please take all possible precautions with your puppy or dog.

    parvo is more common in puppies because their immune system is weaker.
    i wouldnt really worry about it.

    parvovirus (pär’vōvī’rəs) , any of several small DNA viruses that cause several diseases in animals, including humans. In humans, parvoviruses cause fifth disease, or erythema infectiosum, an acute disease usually affecting young children. Symptoms include a rash that spreads from the cheeks (hence the common name slap-cheek disease) to the extremities, low fever, fatigue, and, in adults, mild to severe joint pain and swelling. Treatment consists of bed rest, fluids, and acetaminophen for the fever. Parvoviruses have also been associated with aplastic anemia, arthritis, and spontaneous abortion in humans.

    Dogs, wolves, and coyotes can become infected with canine parvovirus. Puppies are most susceptible to the virus, which causes diarrhea, vomiting, and fever. There was an outbreak of canine parvovirus in the United States in 1978, and it has become more common worldwide since then. Feline distemper, also called feline panleukopenia, an often fatal disease of cats, raccoons, and minks caused by a parvovirus, is characterized by fever, dehydration, loss of appetite, and a reduction in white blood cells. Annual vaccination against parvoviruses is routine in cats and dogs.

    How long do I need to wait before getting a new dog after loosing a puppy to the parvovirus?
    I lost my Puppy this past week and would like to know how long I need to wait or what factors into getting a new dog. I would love to be able to get a dog from a shelter but dont want to risk one getting sick from my yard or something. Does anyone know the lifespan of this virus or how it would affect a well vaccinated adult dog? Any advice is welcome.

  7. aquarias says:

    Has anyone had adult onset parvovirus?
    I was sick as a dog for 1 1/2 years. The only thing I was positive for was parvovirus. It was horrific. I also developed severe anxiety disorder. I didn’t think I was ever going to get better. The docs couldn’t help at all. I know this is strange, but can anyone relate?

    Parvovirus is a dog disease fella. People don’t get it.

  9. staffieowner says:

    Parvo is an awful killer of dogs and I believe can last for around a year if not a little longer. YOu need to consult your vet about this. But if your new dog is vaccinated (the full 2 injections) about a week before he / she comes home and you keep her yearly boosters up to date then you should be fine.

    Good luck and I am sorry for your loss

    P.s I have had a look for you and it is 1 – 7 months.
    How long does Parvovirus last in the environment?
    The Parvovirus family of viruses are particularly long-lived in the environment, lasting anywhere from 1 to 7 months — commonly surviving 5-7 months in an outside environment. Due to the large amounts of virus particles shed in the feces of an infected dog (shedding lasts two weeks or more after exposure) and the longevity of the virus, complete eradication of the virus is often impossible; but seriously check out this site it will tell you all you need to know.

    Obviously if your dog has all its shots and doesn’t have parvo, he couldn’t give it to the other dog.
    Unless maybe your dog stepped in some parvo poop and then went over to your friend’s house with parvo virus on his feet. But then, your friend could have stepped in parvo poop herself, even very old poop. Or maybe a dog with parvo pooped in her yard. The virus lasts a long time in the environment. That’s why it’s so important to get dogs vaccinated.
