Parvo Virus

Canine parvovirus (CPV) is the most dangerous and contagious virus that affects unprotected dogs. When it was first discovered in 1978, most of the puppies under five months old and 2% to 3% of older dogs died from CPV. But subsequently a parvo vaccine has helped control its spread, and CPV infection is now considered most threatening to puppies between the time of weaning and six months of age. Adult dogs can also contract the virus, although it's relatively uncommon. All breeds of dog can be infected, but Rottweilers and Doberman Pinschers are more susceptible and have less chance of recovering.


CPV affects only dogs, and cannot be transmitted to humans or other species. However, other animals and humans can carry it to dogs. Dogs who become infected have a 50-50 chance of survival. If they survive the first four days, they will usually recover rapidly, and become immune to the virus for life. Most puppies will die without medical treatment.



The source of CPV infection is fecal waste from infected dogs. It has been diagnosed anywhere groups of dogs are found: dog shows, obedience trials, breeding and boarding kennels, pet shops, animal shelters, parks, and playgrounds. Dogs that spend their time confined to a house or yard and are not in contact with other dogs have much less chance of exposure to CPV. It's easily transmitted via the hair or feet of infected dogs, and also by contaminated objects such as cages or shoes. CPV is hardy and can remain in feces-contaminated ground for five months or more if conditions are favorable. Although most disinfectants cannot kill it, chlorine bleach is quite effective. There may be other means of transmission of CPV, but they are not known at this time.


Two forms of CPV have been identified: diarrhea syndrome and cardiac syndrome.


Diarrhea syndrome, or enteritis, has an incubation period of five to fourteen days. Dogs with enteritis act like they are in extreme pain. Early symptoms are depression, loss of appetite, vomiting, high fever, and severe diarrhea. Feces can be either grayish or fluid and bloody. Rapid dehydration is a danger, and dogs may continue to vomit and have diarrhea until they die, usually three days after onset of symptoms. Others may recover without complications and have no long-term problems. Puppies can die suddenly of shock as early as two days into the illness.


The second form of CPV is cardiac syndrome, or myocarditis, which can affect puppies under three months old. There is no diarrhea because the virus multiplies rapidly in muscle cells of the immature heart. Puppies may stop suckling and then collapse and die within minutes or days. No effective treatment is available for cardiac syndrome, and surviving puppies may have permanently damaged hearts.


The initial diagnosis of CPV can usually be made by a veterinarian after observing the dog’s symptoms; however, vomiting and diarrhea can be caused by a number of diseases. The rapid spread of illness in a group of dogs is another indication that CPV may be the culprit. A more definitive diagnosis of CPV can be made by testing feces for the virus, either at the veterinarian's office or through an outside laboratory.


Treatment for CPV should be started immediately. Hospitalization is necessary, except in relatively mild cases. Dogs must be kept warm. Dehydration is treated by replacing electrolytes and fluids and controlling vomiting and diarrhea. Antibiotics are used to prevent secondary infections. No drug is yet available that will kill the virus.


The easiest way to prevent CPV in adult dogs has been through annual vaccinations, although increasingly, veterinarians are recommending that vaccinations be administered every three years. Puppies need a series of booster shots, because of uncertainty about when maternal immunity wanes and the time the vaccine can provide puppies with their own immunity. This may be as early as six weeks of age or as late as fourteen weeks of age. If there is still a high level of maternal antibody present in the puppy, it will interfere with a vaccination. Veterinarians recommend that puppies get boosters every three weeks until they are sixteen weeks old, and they should be kept separate from unvaccinated dogs. Vaccinations given to puppies as well as adults also protect against other serious canine diseases like distemper, infectious hepatitis, leptospirosis, parainfluenza, and coronavirus.


Parvo vaccinations are usually required for participation in puppy obedience classes and for boarding your dog at kennels. A vaccination does not guarantee that your puppy will be safe from the virus, but it's good protective insurance.

A parvo-infected dog can shed the virus in his feces, which makes him extremely contagious to other dogs. The following precautions will help prevent the spread of this disease.


· Keep the dog isolated from all other dogs for at least a month after recovery.

· Pick up all the dog's stools in your yard.

· Use chlorine bleach and water to clean food and water bowls. Wash the dog's bedding in bleach and hot water. Disinfect all areas that the dog has been in, including linoleum floors, crates, etc.

· If you have any other dogs who are two years old or younger, or who have not had parvo vaccinations, take them to your veterinarian immediately for a booster shot.

· Feed your dog a bland diet until he recovers. Reintroduce regular food slowly.


A healthy puppy or adult dog should never be allowed contact with the feces of other dogs when walking or playing in public. Dispose of waste material properly and try to keep lawns, sidewalks, and street gutters clear of feces from neighborhood dogs.

Canine Parvovirus is a very serious disease. The virus attacks the lining of the intestine. When the lining of the intestine dies, it is passed in the puppy's poop. Now, the intestines have no lining, so that the little blood vessels that once waited to pick up nutrients from the gut now are exposed to all of the bad bacteria that hangs out there. The bacteria get into the bloodstream and cause a blood infection. The dead lining plus the open blood vessels is why we see the bloody diarrhea in these puppies.

The puppy also has horrible vomiting from all of this irritation. With both vomiting and diarrhea, the puppy becomes dehydrated. The bacterial blood infection and the dehydration is usually what causes the puppy to die.

Sometimes, older puppies have a little immunity built up and respond to very conservative home treatment. The best chance for the puppy is to get him into a vet so that they can give him fluids directly into his veins, medicine to control the vomiting, and antibiotics to prevent the bacterial blood infection. You might be able to at least get some fluids under the skin, an anti-vomiting shot, and an antibiotic injection from your vet to give your pup a better chance at surviving.

Contrary to another poster, Parvo is **not** always fatal. About 85% of dogs that are able to receive the first treatment mentioned above (IV fluids, etc.) survive the virus. If you have no means to seek veterinary care, your pup might have about a 50% chance.

Vaccinated puppies and dogs certainly have plenty of immunity (very important to do all of the puppy shots every 3 weeks starting at 6 weeks of age!).

Call your vet's office and see if you can afford treatment. If not, many vet's have a list of things you can try at home. Pedialyte (unflavored) is a good thing to use until you speak with your vet.

contrary to popular belief...puppy's can overcome parvo!! don't give up!! my room mate's pup overcame it even at a rather late stage in the disease. take it to the vet immediately though. what kills puppy's from parvo is the dehydration(not having enough fluids in the body) and that is what needs to be treated until the parvovirus has run it's course. it will also need some medications as well, and clean everything that was in contact with the pup with water mixed with bleach with a 1:30 ratio (bleach to water). before cleaning the objects, remove all the feces adn vomit so that the bleach can do it's work as well as it can. the dog might have to stay in the vet for a little to get an IV which will make sure it's getting the fluids it needs. goodluck and i hope this helps a little. just remember not to give up!!

Well,my mom's 14 month old Cocker has just been diagnosed with this on Monday. He began not eating last Friday and throughout the weekend he became less active. Sunday he began vomiting and had lots of diarrhea. First thing Monday morning I took him to the vet and confirmed theParvo diagnosis.The vet gave him a 75% chance of survival if he stayed there for IV fluids and meds($550) or 30% chance if we took him home with oral medications, so we had to bring him home.Since I am a paramedic and my mother a nurse we called the vet back and asked if we could administer the IV fluids ourselves.But this vet absolutly would not give us the information we needed to give the proper amounts of fluids(guess he wanted us to pay him to do what we could do ourselves). Anyway,he did say the we could give him IV fluids, but we put them just under his skin at the back of his neck. I didn't think you could do this but at this point we tried anything! So since monday he has has 3 IV treatments totalling 750cc of LACTATED RINGER"S solution. This morning I come home to find the dog as active as ever. Jumping around playing, barking. He has to be on bland diet and plenty of oral fluids for a few days, but he seems to be doing well. He has not vomited or had any diarrhea since Monday. So I would adives you to go to the vet, get the meds and ask about how to do thid type if IV (it is very easy to do). Good LUck!

I had a dog that got this and gave her children's Tylenol. But if the dog has a bloody stool already - I'm sorry but it is too late. Go by the weight of the dog as you would a child on the instructions. Keep dog in tub, on disposable linen. Keep dog in even temperature room. Try to keep the dog drinking Gatorade and water. If you have to syringe fluids to dog ever so often.

Dogs with Parvo need to be cared for by a VET, there is nothing you can do for him. If you love your dog let the vet save it's life.

we kept our dog in the tub gave him what the vet prescribed, liquid kaopectate, and fed him boiled beef and rice. If you try this make sure to WASH YOUR HANDS EVERY TIME you touch the dog. 99% of dogs who get this don't make it. We got lucky. He was much smaller than he should have been when he grew up, but he did grow up. Just deal with this day to day and stay grounded in reality. Your pup might make it, But the odds are against it. wishing you luck.......
