With proper treatment, survival rates can approach 90%. Since parvovirus is highly contagious, isolation of infected dogs is necessary to minimize spread of infection.
Parvo is a potentially fatal disease. 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.
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%.
While most dogs that recover from parvovirus live a normal, healthy life, one study found that some dog patients were more likely to develop chronic GI issues. For this reason, it is important that your recovered pet is receiving a complete and balanced diet.
Adult and older dogs who contract parvo have better chances of survival than puppies. The survival rate of dogs treated by a veterinarian is 68–92%.
Parvo may affect dogs of all ages, but is most common in unvaccinated dogs less than one year of age. Young puppies less than five months of age are usually the most severely affected, and the most difficult to treat. Any unvaccinated puppy that shows the symptoms of vomiting or diarrhea should be tested for CPV.
Within 24-48 hours, copious vomiting and diarrhea present, often containing blood in the later stages. If not promptly and effectively treated, the dehydration, septic shock, and stress on the animal's heart can be fatal.
Parvovirus isn't curable, but supportive treatment, such as around-the-clock care with intravenous fluids, antibiotics, and nutritional support until the patient's immune system takes over, may defeat the virus.
Parvo is a preventable disease, but even vaccinated dogs are not 100% protected from the virus. Vaccines for the parvovirus are recommended for all puppies and are usually given in a series of three shots when the pup is between 6-to-8 weeks old, again at 10-to-12 weeks, and at 14-to-16 weeks.
The Spread of Canine Parvovirus 'Parvo'
The disease is so infectious that even a human that has unknowingly been in contact with an infected dog can spread the virus to puppies and other dogs just by touching them. Which means that an innocent pat on the head can become the beginning of a life-threatening condition.
There is no cure for Parvo in puppies, however, your vet will offer supportive treatments to address symptoms such as vomiting and diarrhea. It's critical that your pup gets enough hydration and nutrition to recover from Parvovirus.
Parvo in dogs usually takes 10 to 14 days to exit the puppy's system. However, it can differ according to the severity of the infection. During this time the pup can pick up a secondary infection that can increase the recovery time.
Pets can be hospitalized up to 7 days in some cases but in most cases 3-5 days. The survival rate for hospitalized parvo dogs is approximately 90%. Pets are able to go home when they are hydrated, no longer vomiting and are eating willingly.
Vaccinations stimulate the immune system to make a response. In a disease that destroys the immune system, there is nothing left to fight the disease. This is how some dogs can become infected with Parvovirus, and it's not related to vaccine failure or lack of vaccine immunity although it may initially appear this way.
Reason #10: Parvo has no cure
Because parvo is a virus, antibiotics cannot stop its progression. All we can do for a dog with parvo is provide supportive treatment until her immune system is strong enough to fight the virus on its own.
IV fluids and management of electrolytes are the cornerstone of treatment for parvo. Antibiotics are given to prevent secondary infections, along with medications to help relieve vomiting, nausea and pain. De-wormer should be given since many puppies also have intestinal parasites that can worsen diarrhea.
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.
They are very ill, with significant abdominal pain. The virus is so strong that it literally causes the lining of the intestines to slough. It is painful to eat, and with the severe diarrhea and vomiting that is present, they rapidly become dehydrated.
It is essential to begin treatment as soon as a dog has been diagnosed. With proper veterinary care, the survival rate of dogs who contract parvo can be up to 90 percent, but without treatment, the mortality rate is more than 80 percent.
Dehydration is very serious; dogs with canine parvovirus refuse water and quickly dehydrate due to their constant vomiting and diarrhea symptoms.
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.
In the U.S., people tend to get infected with parvovirus B19 more often in late winter, spring, and early summer. Mini-outbreaks of parvovirus B19 infection occur about every 3 to 4 years. Since parvovirus B19 only infects humans, a person cannot get the virus from a dog or cat.
