There is no simple answer to the question how long does a dog live with parvovirus? The reason is that there are other mitigating factors. Parvovirus is one of the most feared illnesses of dog owners, especially those with puppies, as they are usually the most at risk canines. If untreated, this disease has the great possibility of being fatal. This is why it is understandable you will want to know how much time you have if you start to see the first symptoms of parovovirus.

In this AnimalWised articles we not only talk about life expectancy of parvovirus infected dogs, but we go into what to look for and what to do if you see symptoms. We will also discuss the treatment of this potentially deadly disease and give some background information. The most important thing to know is that immediate action is required if symptoms of this infection are detected.

What is parvovirus?

Parvovirus is a viral disease which is most commonly transmitted orally-fecally in dogs. This means when a dog eats or is around another dog's faeces infected by parvo-virus, this dog may also contract the infection. An infected dog can release the virus in their stools for several weeks. If the dog defecates in very cold weather, parvo can also live dormant in these frozen stools. Additionally, it can be transported on the legs (especially if there is fecal matter on the fur), as well as other parts of the body and even objects touched by an infected dog. When it is contracted the disease is acute and very contagious.

The virus attacks cells which are reproducing, such as those lining the intestinal tract, and it is this destruction of cells which causes the risk of death. Although parvovirus can affect any dog, puppies between the ages of 6 and 21 weeks are particularly susceptible. The main symptoms of parvovirus are the following:

  • Anorexia: weight loss occurs due to the dog stopping from eating.
  • Lethargy: the destruction of cells depletes the dog's energy leading to inactivity and a drastic change in their habitual behavior.
  • Fever: parvovirus is usually accompanied by fever.
  • Vomiting: not only the will the dog vomit, but this vomit will have a distinct appearance and smell. Vomit from a parvovirus infected dog will also likely contain blood.
  • Diarrhea: as the virus can affect the digestive tract, diarrhea is profuse, hemorrhagic and/or mucosal. It is accompanied by a loss of fluid which leads to dehydration. Additionally, the presence of blood will indicate a poor prognosis.
  • Abdominal pain: usually caused by the shrinking of the stomach.

If we recognize these symptoms in our dog, we must immediately take them to the vet. Their lives will depend on it, especially if they are a puppy. Rapid action will greatly influence the life expectancy of a dog with parvovirus. If the vet suspects parvovirus, fortunately, there is a rapid test which can determine the presence of this disease in minutes. However, this test can obtain false negatives, so the presence of concurrent symptoms is also important. Also, a blood test will likely be taken to see the extent of the infection. This is partly to rule out the myocardial form of the infection which can result in sudden death.

Can a dog with parvovirus be saved?

Parvovirus treatment requires a thorough treatment of the symptoms to help fight the infection. How long a dog lives with parvovirus depends on the severity of these symptoms and how long they have contracted the infection. The treatment is intensive, requires hospitalization and usually consists of some combination of the following:

  • Fluid therapy to replenish fluid and electrolytes which are lost by frequent diahrrea and vomiting. Since the dog will have trouble eating and drinking, this is a vital way to replace lost nutrients. Once the fluid levels are returned, they will be topped up every time the dog loses more fluid through vomiting, defecating, etc.
  • Broad spectrum antibiotics (those capable of eliminating a wide range of bacteria) to combat opportunistic bacterial infections taking advantage of the dog's lowered immune system. This antibiotic measure helps to reduce the likelihood of complications during treatment.
  • Antiemetics to control vomiting.
  • A blood transfusion may be required since the virus can produce serious anaemia.
  • Parenteral nutrition as the dog will not be able to feed itself at least until the vomiting subsides.

These antibiotics and fluids are usually administered intravenously which requires the hospitalization. The vomiting usually means the dog will be unable to receive the medication orally. Round the clock care and observation is also needed which requires hospitalization. If the animal respond positively to treatment and symptoms begin to reside it can fight the disease. Although this is a serious pathology which can compromise the life of your dog, if treated in time, it is indeed possible to save their life.

Preventing parvovirus in your dog

Preventative measures are so important with parvovirus as it is so contagious and, despite being a relatively recent disease, prevalent. Additionally, these measures are important when it comes to asking how long does a dog live with parvovirus. Whether or not they have been taken can affect the prognosis if they are unfortunate enough to still contract the infection. These parvovirus preventative measures include:

  • Vaccination: respecting the vaccination schedule whether your dog is a puppy or adult is very important, but especially so when they are younger. No vaccine offers 100% protection, but it is also true that a vaccinated animal will be less contagious than a non-vaccinated one. This in turn positively affects life expectancy.
  • Disinfection: cleaning your dog's toys and accoutrements after playing in high risk areas is important.
  • Isolation: keeping puppies which have not finished their immunization schedule is very important. It prevents them from coming in contact with dogs whose immunization is unknown as well as keeping them away from excrement.

The dog's state of health prior to the infection is also important as it will keep their strength in reserve when they need it the most. Apart from quality of life, this is another important reason to maintain the overall health of your dog. If the animal has been properly vaccinated, dewormed and well fed, their life expectancy after contracting parvovirus is increased.

Life expectancy of a dog with parvovirus

As we stated above, the life expectancy of a dog with parvovirus depends on mitigating factors. As a summary, these include:

  • Speed at which veterinary treatment is commenced, the reason for acting quickly when we spot parvovirus symptoms.
  • Adequacy of thew chosen treatment is also important. While most vets will do all they can to help your dog, some may be better trained than others. Also, if there are insufficient resources in terms of antibiotics, antiemetics, etc. this can have a bearing.
  • Presence of blood in stool and vomit means the infection is advanced and can reduce life expectancy prognosis.
  • The virulence of the strain os parvovirus which infects your dog. Some may be stronger and more resistant to treatment.
  • The age of the dog at the time of infection is also important. If they are particularly young or old, they may not have the strength to overcome the disease.
  • The status of the dog's immune system is a mitigating factor as a dog which is already ill from another condition may not be able to fight both infections at once.
  • A few weeks old puppy will also benefit from a mother with a healthy immune system. Maternal antibodies passed down in the womb and through milk will also help improve prognosis.

Due to these factors, it is impossible to give an accurate answer to how long it takes for a dog to die from parvovirus or whether it will survive at all. Likewise, it is also impossible to say it can't make a full recovery. Getting in early and providing comprehensive treatment is the best way to help chances of survival. Once the dog does recover, however, there is no reason it can't lead a long, healthy and happy life.

H Soopy,

If you have been the vet twice and they are confident they are giving the right course of treatment, then you may just have to exercise some patience until the symptoms resolve themselves. If you think the vet is incompetent, then you should go to a different vet for a second opinion. Good luck!

My dog have a virus and he dont want to eat what is the best way he can eat. And is it ok he will take bath?

Hi,

If your dog is refusing to eat, you need to take them to the vet. If they have a virus such as parvovirus, then the mortality rate is very high without treatment.
