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.

    What is parvovirus? How can my puppy get parvovirus? Should I let it walk around the house?
    We have two dogs, one 9, the other we don’t know(but shes not old). We just got this puppy and its 11 weeks old. Our two dogs don’t show any of the sign of having parvovirus. They only go outside for at least 20 minutes added up a day. Can our puppy (Jake) get parvovirus still?
    He has all of his shots except the parvovirus shot. Jake’s getting it on Saturday. The other 2 dogs have had these shots.

    When is it safe to give a puppy the parvovirus vaccine after they’ve recently recovered from the virus?
    My 6 month old puppy recovered from the parvovirus 5 weeks ago. He wasn’t vaccinated in time. I’ve been waiting until I thought it was safe to administer the first set of vaccinations. Of course, the vaccines include the parvovirus. I just don’t want him to relapse. Is it safe to administer it to him?

    Call the Vet in charge at the drug company that makes the vaccine. They are an excellent resource!
    Also, of course, talk to your Vet.
    I am not an expert, and I’m under the impression that once they have recovered from Parvo they should be immune from getting it again…keep asking lots of questions!
    My experience is that any puppy can easily be exposed to Parvo & vaccinations are the only chance they have. Seems to me that 2 out 3 pups that get it die. There is no cure…all that can be done is try to keep them alive & fighting hoping their system will win out. It is completly devastating & heartbreaking…vaccinations on time are far more important than most pet owners realize.
    Their most vunerable time to get it is around 4 months of age…right when a person might think they have the healthiest pup in the world! I breed Shih Tzu & they have 3 vaccinations before they leave my home, 2-3 weeks apart. I use NeoPar (a single antigen for Parvo) & the 5 way Combo shots. I constantly research through Vets & just try to keep learning as I go along.

    How long should a 12 week old puppy with Parvovirus be on IV fluids?
    My new puppy has Parvo and was under a doctors care but due to the holiday weekend he closed the animal hospital and told me to treat my puppy myself. My puppy was on IV fluids for two days and now is home resting. How long shall I wait to take her to another clinic to be hooked up to an IV drip if she will not drink?

    My mom is a vet and ive seen many puppies with parvo virus .

    Yes its curable but you need to take it to the vet immediately, they will get really dehydrated if you dont. It may also cost some money but its all worth it .

    It should take about two weeks at most . Not that long but make sure you get your puppy to the vet because it all depends on how sick your dog is .

    Hope all goes well .

    Chigirl– you are assuming the OP never vaccinated.

    You are also assuming that vaccination means a dog won’t get parvo.

    We have seen plenty of puppies vaccinated who come down with parvo. Maybe the vaccine was given to late…or maybe it was a bad lot…or maybe they just didn’t get enough immunity off of the 1st or 2nd vaccine.

    Even a fully vaccinated older dog can come down with isn’t often, but it seems to be happening more and more. There is talk of parvo mutating, attacking older dogs and killing them faster.

    FIRST OFF, i heard that terriers have better chances of survival from parvovirus. i have no idea why… but idk. my baby JUST had parvo, and he was 8 wks old, and now he is back on track =]] the vet said he had a 60% chance of survival, and she said he was the fastest recovering puppy! And she said dobermans, rottweilers, and black labs (no idea why BLACK labs though) have a higher mortality rate of NOT surviving parvo, and that even though terriers will look practically dead when someone takes them in because of the terrier, and that terriers recover the FASTEST (thats good =]]])

    depends when you took him in, how long you waited, how far the symptoms progressed. if he hadn’t had had bloody stool yet. my puppy hadn’t progressed that much, and we took him in like the 2nd day of parvo?? we gave him pedialyte so he wouldn’t dehydrate, so that kinda helped him…

    i think maybe a 70-90% chance?? the vet said terriers have 80% chance of survival, just because they can jump right back up =]]]
