Can A Dog Get Parvo Twice? The Shocking Truth You Need To Know!

Spread the love

Parvo is a highly contagious viral disease that commonly affects dogs, particularly puppies. It attacks the gastrointestinal and immune systems of dogs, causing symptoms such as vomiting, diarrhea, lethargy, fever, and dehydration.

If you’re a dog owner, then you know how devastating parvo can be. Not only does it cause physical suffering to your beloved pet, but it can also put a significant emotional and financial strain on you.

After going through the ordeal of treating a dog with parvo, many pet owners may wonder if their dog can get the virus again. The answer is not always straightforward, as there are several factors at play when it comes to whether or not a dog can get parvo twice.

“The shocking truth,” as our title phrases it, is that even if your dog has contracted and survived parvo once, they are still at risk of getting the virus again. However, whether or not they will depends on various things like vaccination status, age, and overall health condition.”

Continue reading this article to learn more about the chances of a dog getting parvo twice, what causes the virus, and the steps you can take to prevent your pooch from contracting it in the first place.

Understanding Parvo and Its Effects on Dogs

What is Parvo?

Parvo, or canine parvovirus (CPV), is a highly contagious virus that affects dogs of all ages, but it’s more commonly found in puppies under six months old. The virus targets the intestinal tract and attacks rapidly dividing cells, leading to severe vomiting and diarrhea.

The infection can cause dehydration, which is life-threatening if not treated immediately. Moreover, the virus weakens the immune system, making infected dogs susceptible to secondary infections such as pneumonia.

“Canine parvoviral enteritis causes gastrointestinal symptoms, including vomiting, diarrhea, fever, lethargy, abdominal pain, anorexia, weight loss, and dehydration.” – Merck Veterinary Manual

How Does Parvo Affect Dogs?

Dogs recover from CPV through antibodies produced by their own immune systems; however, the recovery rate depends on how early the infection was diagnosed and how soon treatment began. Once a dog battles parvovirus, he builds immunity against future exposure. Nevertheless, immunocompromised dogs may be at risk for contracting and developing complications regardless of whether vaccines have been administered.

If you’re wondering if your dog could catch Parvo twice, it’s unlikely. Generally, once dogs successfully fight off this virus, they develop lifelong immunity to it. However, there are instances when previously infected dogs might get another strain of parvovirus. Furthermore, with newer emerging strains of parvovirus from different countries, previous vaccinations’ effectiveness may wear off over time. Therefore, it is important that your dog keeps up-to-date on its parvo vaccine schedule.

“Disease prevention through vaccination is absolutely vital because the disease is so serious and sometimes difficult to treat, and because appropriate husbandry measures are relatively straightforward.” – Blue Cross for Pets

Thus, if your dog has suffered from parvo before, there is a minimal chance of that happening again. However, you must always ensure they remain up-to-date on vaccinations to keep them safe.

  • Keep puppies separated from unvaccinated adult dogs or those with unknown vaccination status.
  • Avoid taking canines to places where several unfamiliar dogs interact frequently like pet shops and parks
  • If you must go to susceptible locations, carry the pup rather than letting it saunter around on its feet.
  • Do not let the puppy play with toys or bowls belonging to other animals.
  • Even after immunization, limit access for young vaccinated dogs until the complete set of vaccines is administered.

Vaccination will provide overall protection against CPV, but prevention remains the best solution to avoid contamination.

“The best prevention method includes contacting your veterinarian regarding the vaccine whenever possible,” says Dr. Karen Becker, DVM, “Making sure that your dog enters into treatment immediately when he’s diagnosed with Parvo… keeping pups away from potentially contaminated areas, and regularly disinfecting items that may be exposed to the virus.”

What Happens to Dogs After They Recover from Parvo?

Recovery Time

The duration of a dog’s recovery process after being infected with parvovirus depends on various factors, such as the severity of the disease and the age of the dog. Generally, it takes about one week for mild cases while it can take up to several weeks or even months for severe ones.

If your dog is showing signs of illness, such as vomiting, diarrhea, fatigue, and loss of appetite, bring them to a veterinarian immediately. Early diagnosis and treatment are crucial in increasing their chances of survival. Treatment often involves hospitalization, administration of medication and fluid therapy to stabilize and rehydrate the dog’s system.

Long-Term Effects

After recovering from parvo, dogs may still experience some long-term effects, especially if they had a severe case. These include:

  • Digestive problems – The virus damages the lining of the gastrointestinal tract, which causes digestive issues like chronic diarrhea, reduced food absorption and nutrient deficiencies.
  • Immune deficiency – Parvo attacks white blood cells that fight infections, leaving a dog vulnerable to other illnesses.
  • Cardiac abnormalities – Very young puppies who survive severe cases of parvo may develop heart diseases later in life due to the damage caused by the virus to their heart muscles.

If you notice any persistent symptoms like unexplained weight loss, vomiting, diarrhea, lethargy, or general weakness, contact your vet immediately.

Post-Recovery Care

When your dog comes home after a successful parvo treatment at the animal hospital, they will need lots of rest and attention from you. Here are some tips for caring for your dog during their recovery period:

  • Keep them warm and comfortable, and ensure they have adequate bedding to sleep on.
  • Feed them small portions of bland, moist food at intervals throughout the day to help settle their stomach and restore nutrition. Chicken broth or rice water are good choices as well
  • Prevent them from engaging in any strenuous activities that could cause stress while gradually reintroducing normal physical activity over time.
  • Continue medications prescribed by your veterinarian.
  • Clean up after your pet carefully and efficiently, since parvo is highly contagious and can live outside the body for a long time; it might re-infect other animals if not properly handled.

How to Prevent Future Infections

The best way to prevent your dog from getting parvo again is to keep them vaccinated, limit exposure to contaminated areas until fully recovered, and practice proper hygiene. Here are some tips for preventing future infections:

  • Vaccinate regularly – Most veterinarians recommend puppies beginning vaccination around six weeks of age, followed by boosters every three to four weeks, resulting in full coverage a few months later. Adult dogs require annual vaccinations against common diseases, including Parvovirus.
  • Eliminate bacteria – Since parvo survives well indoors and outdoors, disinfect your home regularly using specific cleaners designed to kill virus. Diluting bleach or ammonia can be used but should be done with caution as these substances may irritate respiratory systems.
  • Limit public access Until Fully Vaccinated – Avoid areas where unvaccinated dogs congregate, such as parks, where high amounts of fecal matter concentrate. This means limiting walks only to protected spaces like your yard or using a dog park once your pets have completed their vaccination cycles.
  • Good Hygiene – Bathe your dogs regularly in conjunction with routine brushing. This helps remove dirt and bacteria, enhancing immunity as well as preventing the infection of other parasites that may pose risk factors or weaken natural immunity over time. Finally, keep up with all vaccinations to ensure full immune protection over time.

Parvo can be highly contagious and fatal if not treated promptly and aggressively; therefore, it is essential to educate yourself about what you should do to protect your pet during recovery while working alongside professionals to prevent future outbreaks. With ongoing prevention practices, combined with effective treatment, survival rates for parvovirus-infected dogs are significantly increased.

Does Immunity to Parvo Last a Lifetime?

The Duration of Immunity

Parvovirus, or parvo for short, is a highly contagious and deadly virus that affects dogs. Once a dog has been infected with parvo, the immune system will begin producing antibodies to fight off the infection.

These antibodies can provide immunity to future infections, but how long does this immunity last? According to veterinarians, most dogs develop immunity from parvo between six and 12 weeks of age, either through vaccination or previous exposure to the virus, and this immunity typically lasts for many years.

Some sources suggest that younger dogs may need additional booster vaccinations to maintain their immunity against parvo. This is because their immune systems are not fully developed yet, and they may not produce high levels of antibodies in response to the vaccine.

Factors That Affect Immunity

Even if a dog has already developed immunity against parvo, there are several factors that can affect its ability to fight off an infection:

  • Age: Younger puppies and older dogs tend to have weaker immune systems, making them more susceptible to infections like parvo.
  • Health: Dogs with underlying health conditions or weakened immune systems due to illness or medication may also be at higher risk of contracting parvo.
  • Environment: Parvo can survive on surfaces like floors, toys, and clothing for months, so dogs who frequent areas where other dogs have been (like parks, pet stores, or daycare facilities) may be exposed to the virus even if they haven’t come into direct contact with an infected dog.

If your dog has already had parvo, it is important to take precautions to avoid a potential re-infection. Keeping your dog up-to-date on vaccinations and avoiding areas where infected dogs may have been can help reduce the risk of exposure.

“Parvovirus has long been feared by veterinarians due to its rapid onset, high morbidity rate, and severe clinical signs. Prevention through vaccination remains the best defense against this virus.” – The American Kennel Club

If you suspect your dog has contracted parvo again, it’s important to seek veterinary care immediately. While immunity from previous infections or vaccinations can provide some protection, repeat infections can still be serious and even fatal without proper treatment.

The bottom line: while most dogs develop long-lasting immunity to parvo after the initial infection or vaccine series, there are several factors that can affect their ability to fight off future infections. It’s important to work with your veterinarian to determine the best vaccination schedule for your pet and take steps to minimize exposure to potentially infectious environments.

Can Dogs Get Different Strains of Parvo?

Dogs can definitely get different strains of parvovirus, which is highly contagious and potentially fatal. There are two types of parvo: CPV-1 and CPV-2. The latter variety is further divided into three subtypes: CPV-2a, CPV-2b, and CPV-2c.

CPV-2b was first identified in the late 1970s and caused a significant outbreak in dogs. CPV-2c emerged in Europe in the mid-2000s and has since spread to other continents; it’s now considered the most common subtype worldwide, surpassing even CPV-2b in prevalence. CPV-2a is rare and hasn’t been seen in North America for many years. Meanwhile, CPV-1 isn’t typically associated with serious illness in dogs these days.

Types of Parvo Strains

As previously mentioned, there are three main subtypes of CPV-2:

  • CPV-2a: This strain has become very uncommon in recent years thanks to widespread vaccination. It originally emerged after CPV-1 mutated.
  • CPV-2b: This strain caused serious outbreaks in the past before vaccines became widely available in the 1980s. Today, annual boosters protect against this at-risk subtype.
  • CPV-2c: This newer strain surfaced around 2006 in Italy and rapidly spread across Europe, Asia, and Africa. Unlike CPV-2a and -2b, it seems able to overcome some vaccine defenses and cause more severe disease.

How to Protect Your Dog from Different Strains of Parvo

The most effective way to protect your dog from all strains of parvovirus is through vaccination. Puppies should receive their first shots at six weeks old, with boosters at three- or four-week intervals until they’re 16 weeks old. After that, dogs get yearly vaccine boosters throughout life.

You can also minimize your dog’s risk of exposure by avoiding public spaces like parks and dog runs until they’ve been fully vaccinated. Additionally, wash your hands frequently and avoid contact with other dogs’ feces when you’re out walking. If you have more than one dog at home, isolate any new animals you bring in until they’ve tested negative for the virus and received adequate vaccinations.

Can Vaccines Protect Against All Strains?

Vaccinations are highly effective against CPV-2a and -2b and provide considerable protection against CPV-2c as well. However, according to some research, CPV-2c may be able to overcome immunity provided by some vaccines. This isn’t a cause for panic, however — most vaccinated dogs can still recover from CPV-2c if they contract it. Indeed, prompt medical care is often enough to save even unvaccinated dogs with parvo.

What to Do If Your Dog Has Been Exposed to a New Strain

If you suspect your dog may have come into contact with a strange strain of parvo or at-risk canine distemper or hepatitis, speak to your vet right away about whether additional vaccinations are necessary. Early intervention gives your pet the best chance at surviving these dangerous diseases. Some symptoms to watch out for include lethargy, vomiting, diarrhea (potentially bloody), loss of appetite, and fever.

“Vaccination is a crucial step in preventing serious illness from all strains of parvo,” says Dr. Judy Morgan, a holistic veterinarian and author based in New Jersey. “Owners should also be diligent about avoiding high-risk areas and keeping up with annual boosters.”

How Can You Prevent Your Dog from Contracting Parvo Again?


According to the American Veterinary Medical Association, vaccination is the most effective way of preventing parvovirus infection in dogs. Puppies should begin receiving a series of vaccinations between six and eight weeks old, with boosters given every three to four weeks until they are 16 weeks old. Adult dogs who were not previously vaccinated or whose vaccination status is unknown should also receive the initial vaccine series.

A yearly booster shot is necessary to maintain immunity against parvovirus. Pet owners who reside in areas where cases of parvovirus outbreak are common must follow their veterinarian’s recommendation about additional booster shots.

Proper Hygiene and Sanitation

Dogs that have survived parvovirus remain contagious for up two months after recovery. To protect your pet and others, proper hygiene and sanitation practices must be implemented.

All surfaces contaminated by feces, urine, vomit etc., including grass in yards, floors, bedding, and cages need disinfection using bleach solution (1 part bleach: 32 parts water). However, wooden floors may become pitted and corroded from bleach, so it’s important to check with manufacturers’ instructions before use. Furthermore, carpet shampoo and cleaning agents sanitize carpets effectively, but it’s recommended that these cleaners be added specifically to prevent virus remnants. Additionally, preventive measures such as washing hands thoroughly after handling an infected dog, quarantine time for other dogs, wearing gloves when cleaning up, and keeping your puppy away from public places known for harbor diseases provide extra precautions.

“Hygiene is two-thirds of health.” -Lebanese Proverb

Parvo Virus is a highly contagious virus that can easily infect your dog if it’s not properly vaccinated or disinfected from exposure. The best preventive measure after infection being proper hygiene and sanitation, while vaccinating gives the highest assurance of disease prevention. Keep an eye on your dog’s behavior so you may spot any symptoms early on!

What to Do If Your Dog Shows Symptoms of Parvo

Recognizing Symptoms

If your dog has previously had parvo, you may be wondering if they are safe from contracting the disease again. Unfortunately, dogs can get parvo more than once, especially if their immunity to the virus is low.

The first step in preventing parvo recurrence is recognizing the symptoms early on. Common signs include vomiting, diarrhea (often bloody), fever, lethargy, and loss of appetite. It’s important to note that not all dogs show every symptom.

“Parvovirus is extremely contagious, so there’s a high risk of exposure for any unvaccinated dogs.” -American Kennel Club

If your dog shows any of these signs, it’s crucial to act fast to prevent further complications. Early detection and treatment significantly increase your dog’s chances of survival.

Seeking Veterinary Care

After recognizing the signs of parvo, seek veterinary care immediately. Your vet will diagnose your dog with parvo based on their symptoms, medical history, and laboratory tests.

The primary goal of treatment is to combat dehydration and control secondary infections. This may involve hospitalization, intravenous fluids, antibiotics, antinausea medication, and anti-inflammatory drugs. However, keep in mind that even with proper treatment, parvo can still be deadly.

“Early recognition and aggressive intervention improve survival rates in dogs infected with this virus.” -American Veterinary Medical Association

Your vet may also recommend isolation from other pets and thorough disinfection of your home and yard to prevent the spread of infection.

To protect your pet from future outbreaks, ensure that all household dogs receive the parvo vaccine. Puppies should have a series of vaccinations starting at 6-8 weeks old, with booster shots every few years. Consult your vet for specific recommendations based on your dog’s individual needs.

“Prevention is the key to avoiding this disease.” -Canine Journal

A dog can get parvo more than once if their immunity is low. Recognizing symptoms early and seeking veterinary care immediately are crucial in treating the disease and increasing chances of survival. Vaccination and proper hygiene practices are also essential in preventing future outbreaks.

Frequently Asked Questions

Can a dog get parvo more than once?

Yes, a dog can get parvo more than once. However, it is rare for a dog to get reinfected with the same strain of the virus. If a dog does get parvo again, it is likely due to exposure to a different strain of the virus or an inadequate immune response to the initial infection.

Is it possible for a vaccinated dog to get parvo twice?

Yes, it is possible for a vaccinated dog to get parvo twice. Although vaccines are highly effective, they are not 100% foolproof. In some cases, vaccinated dogs may not develop a strong enough immune response to fully protect them from the virus. Additionally, vaccines do not protect against all strains of parvo.

What are the chances of a dog getting parvo again after recovering once?

The chances of a dog getting parvo again after recovering from the virus once are low, but not zero. Dogs that have recovered from parvo develop immunity to the specific strain of the virus they were infected with. However, they may still be susceptible to other strains of the virus or other diseases that weaken the immune system.

What are the symptoms of parvo recurrence in dogs?

The symptoms of parvo recurrence in dogs are similar to those of the initial infection. These include vomiting, diarrhea, lethargy, and loss of appetite. In severe cases, dogs may also experience fever, dehydration, and bloody diarrhea. If you suspect that your dog has a recurrence of parvo, it is important to seek veterinary care immediately.

How can you prevent your dog from getting parvo again?

The best way to prevent your dog from getting parvo again is to ensure that they are fully vaccinated. Additionally, you should take steps to minimize their exposure to the virus, such as avoiding contact with infected dogs and cleaning and disinfecting any areas where infected dogs have been. It is also important to maintain your dog’s overall health and wellness, as a strong immune system can help protect them from a variety of diseases, including parvo.
