Parvo virus causes severe life threatening diarrhea, often the diarrhea has blood in it. Once a puppy has symptoms of parvo, if left untreated they can die within 48 - 72 hours. It can be simply diagnosed and survival is possible if treated soon enough. If left untreated the mortality rate is as high as 91%.
The canine parvovirus (CPV) is a highly contagious gastrointestinal disease which affects unvaccinated, insufficiently vaccinated, or improperly vaccinated dogs and results in a fatality rate greater than 90% if left untreated.
The survival rate of dogs treated by a veterinarian is 68 to 92 percent, and most puppies that survive the first three-to-four days make a complete recovery. Recovery times vary depending on the severity of the case, but it usually takes approximately one week for puppies to recover from parvo.
The survival rate for hospitalization is 90%. The survival rate for at-home care is 50%.
The highest risk of death occurs around 24-72 hours after you see the symptoms of parvo in dogs. If a puppy is hospitalized, given lots of supportive care, and monitored closely, the survival rate is usually around 75-80%.
The average recovery time for parvo in dogs is between 5 to 10 days depending on the severity of the infection. Since the immune system is very weak during this time, it's possible the dog may pick up a secondary infection that can lead to an increase in the recovery time.
The near-death signs of parvo include severe lethargy, continuous bloody diarrhea, anorexia, and bloody vomiting. You may not want to admit it to yourself, but this is the point of no return. So consider doing a humane thing by putting your puppy to sleep.
Survival from a parvovirus infection is possible, but depends on age, size and how sick the dog is when owners first seek care. Most patients will not survive without treatment. Starting medical treatments when illness first sets in will increase the likelihood of recovery.
Commonly called “parvo”, the organism is very stable in the environment, able to withstand freezing temperatures and many disinfectants to survive as long as seven months in a contaminated area.
Adult dogs with parvo will remain contagious for around 4-5 days and puppies can remain contagious for up to 10 days after a clinical recovery.
Days 2–5: Pup shows first signs (not eating, drooling, etc.) Days 5–21: Pup slowly recovers, begins showing interest in food, stops vomiting, stool slowly begins to harden.
Puppies are at the greatest risk for parvo between the ages of 6 weeks to 6 months. Puppies can receive their parvo vaccinations at 6, 8 and 12 weeks of age. They must receive a full series of vaccinations to ensure complete immunity. Puppies require a parvo booster vaccine between 14 and 16 weeks of age.
You can tell if your dog is getting better from parvo if their stool is starting to go back to standard color and consistency. If there's no blood and the feces are firmer, it means that the intestines are healing well.
There is no treatment to kill the virus once it infects the dog. However, the virus does not directly cause death; instead, it causes loss of the lining of the intestinal tract and weakens the immune system by affecting the white blood cell numbers.
Conclusion: Monitor & Consult Vet if Necessary
While it's true that home remedies like bone broth, coconut water, and probiotics may provide some comfort and help alleviate symptoms in your four-legged friend, it's important to remember that Parvo is a serious illness that requires professional care.
The best household cleaner to use to kill parvovirus is bleach (1 part bleach to 30 parts water). It should be used on hard surfaces including tiles, concrete, paving bottoms of shoes etc – leave the bleach on the surface at least 10-15 minutes. Anything that can be washed in bleach should be.
Often infected animals rapidly dehydrate, and in severe cases progress to shock and death. Occasionally parvovirus attacks the heart muscle of puppies, and can cause sudden death. It is extremely painful for puppies and dogs.
Symptoms of Parvo
Your dog will not drink water nor eat, and very soon the pup will be stretched out and down on the ground, unable to get back up. They will become limp, weak, and unable to hold themselves up. Parvovirus, when left untreated, is often fatal. It requires veterinary oversight.
Once a dog or puppy is infected, there is an incubation period of three to seven days before the onset of first symptoms.
If your dog is being treated by a veterinarian and lives through the first four days after they start showing symptoms, there is a good chance that they will recover from the disease. It can take approximately a week for dogs to recover from Parvo.
Most people don't even get the symptoms of parvovirus B19. Those that do experience mild symptoms that last five to seven days. It doesn't interfere with your daily life for too long unless you're pregnant or immunocompromised.
If your dog is being treated by a veterinarian and lives through the first four days after they start showing symptoms, there is a good chance that they will recover from the disease. It can take approximately a week for dogs to recover from Parvo.
A University of Sydney study has found that canine parvovirus (CPV), a highly contagious and deadly disease that tragically kills puppies, is more prevalent than previously thought with 20,000 cases found in Australia each year, and nearly half of these cases result in death.
Parvo Vaccination Cost
In Australia, parvovirus vaccinations usually cost between $80 – $150. Considering that if your pet contracts the disease, parvovirus treatment costs can be anywhere from $1,500 to $10,000+, the small cost of a vaccine is a worthwhile investment in your pet's health.
