If you have a puppy, you really need to know – how do puppies get Parvo?
Puppies are susceptible to a range of dangerous diseases, including parvo, a highly contagious viral illness that can be fatal if left untreated.
Parvo is a type of virus that primarily affects the intestinal tract and bone marrow.
It is most common in puppies and adolescent dogs, but it can also affect adult or senior dogs, especially if they are unvaccinated.
Understanding how puppies contract parvo is crucial to preventing the spread of the virus.
Puppies can contract parvo through direct contact with an infected dog or by indirect contact with a contaminated object.
The virus is shed in the feces of infected dogs and can survive in the environment for up to a year, making it easy for puppies to come into contact with the virus.
While any dog can contract parvo, puppies are particularly vulnerable due to their underdeveloped immune systems.

Understanding Parvo
Canine parvovirus, commonly known as parvo, is a highly contagious virus that affects dogs, especially puppies.
As PetMD.com states – “Canine parvovirus (CPV or commonly referred to as “parvo”) is one of the most serious viruses that dogs can get.”
It is a viral disease that attacks a dog’s immune and gastrointestinal systems, leading to severe diarrhea, vomiting, and dehydration.
Parvo is caused by a virus known as CPV, which is transmitted through direct contact with infected dogs or their feces.
The virus can also be transmitted indirectly through contaminated objects such as food bowls, toys, and clothing.
Puppies are most at risk of getting the disease within the first few months of life due to their vaccination status and the weakness of their immune system.
However, adult dogs can also contract the virus if they are not vaccinated or have a weakened immune system.
Once a dog is infected with the virus, it can take anywhere from 3 to 7 days for symptoms to appear.
The first sign of parvo is usually lethargy, followed by a loss of appetite and a fever.
As the disease progresses, the dog may experience severe vomiting and diarrhea, which can lead to dehydration and shock.
It is important to note that parvo is a highly contagious virus, and infected dogs can shed the virus in their feces for up to two weeks after symptoms have subsided.
Therefore, it is crucial to isolate infected dogs and disinfect all surfaces and objects that may have come into contact with the virus to prevent the spread of the disease.
Symptoms of Parvo in Puppies
Again, Parvo is a highly contagious virus that affects dogs, especially puppies.
The virus attacks the lining of the small intestine, preventing the absorption of nutrients and leading to severe dehydration.
Here are some of the common symptoms of parvo in puppies:
- Lethargy: Puppies with parvo will be weak and tired, and may not want to play or move around much.
- Loss of appetite: Puppies may not want to eat or drink anything, which can lead to dehydration.
- Fever: Puppies with parvo may have a high fever, which can cause further weakness and discomfort.
- Vomiting and diarrhea: Puppies may vomit or have diarrhea, which can be severe and may contain blood.
- Abdominal pain: Puppies may show signs of abdominal pain, such as whining or crying when touched.
- Depression: Puppies may appear sad or depressed, and may not respond to their owner’s attempts to comfort them.
- Nausea: Puppies may feel nauseous and may drool excessively.
- Leukopenia: Puppies with parvo may have a low white blood cell count, which can make them more susceptible to other infections.
If your puppy is showing any of these symptoms, it is important to take them to the vet as soon as possible.
Parvo can be fatal if left untreated, so early diagnosis and treatment are crucial for a successful recovery.
How Do Puppies Get Parvo?
Parvo in puppies is caused by the canine parvovirus, which is highly contagious and spreads through direct contact with an infected dog or by indirect contact with a contaminated object.
Puppies are particularly susceptible to contracting the virus as their immune systems are not fully developed yet.
The virus is shed in the feces of infected dogs and can survive in the environment for months, making it easy for puppies to come into contact with it.
Puppies can become infected with parvo by sniffing or licking infected feces or objects contaminated with the virus, such as food and water bowls, toys, and bedding.
Dog parks and other public places where dogs gather are common areas for parvo to spread, as infected dogs shed the virus in their feces.
Puppies that come into contact with infected feces or contaminated areas can easily contract the virus.
It is important for puppy owners to be aware of the signs of parvo and to take precautions to prevent their puppies from contracting the virus.
Vaccination is the most effective way to prevent parvo, and puppies should receive their first vaccination at around 6-8 weeks of age, followed by booster shots every 3-4 weeks until they are 16 weeks old.
In addition to vaccination, puppy owners should also practice good hygiene and sanitation to prevent the spread of parvo.
This includes regularly cleaning and disinfecting food and water bowls, toys, and bedding, and avoiding areas where infected dogs may have been.
Risk Factors for Parvo
Although Parvo is a highly contagious virus that can affect all dogs, unvaccinated dogs and puppies younger than four months old are the most at risk. Here are some of the risk factors for parvo:
- Age: Puppies between the ages of six weeks and six months are most vulnerable to parvo. The younger the puppy, the higher the risk of infection.
- Unvaccinated: Dogs that are not vaccinated against parvo are at a higher risk of infection. Vaccination is the best way to prevent parvo infection.
- Breeds: Certain dog breeds are more susceptible to parvo, including Rottweilers, Doberman Pinschers, and American Staffordshire Terriers. However, all breeds can get parvo.
- Environment: Parvo is a highly contagious virus that can survive in the environment for months. Puppies that are exposed to contaminated areas, such as dog parks, kennels, or other areas where dogs congregate, are at a higher risk of infection.
- Health status: Puppies that are already sick or have a weakened immune system are more susceptible to parvo infection.
- Contact with infected dogs: Parvo is highly contagious and can be spread through contact with infected dogs or their feces. Puppies that come into contact with infected dogs or their feces are at a higher risk of infection.
Diagnosing Parvo in Puppies
Diagnosing parvo in puppies can be challenging as the clinical signs can be similar to other diseases.
A veterinarian should perform a thorough physical examination and run diagnostic tests to confirm the presence of the virus.
One of the most common diagnostic tests for parvo is the enzyme-linked immunosorbent assay (ELISA) test.
This test detects the presence of parvovirus antigens in the feces of infected dogs. A positive ELISA test result can confirm the diagnosis of parvo in puppies.
In addition to the ELISA test, a veterinarian may also perform a complete blood count (CBC) and a chemistry panel.
These tests can help evaluate the overall health of the puppy and detect any abnormalities that may be associated with parvo.
Clinical signs of parvo in puppies include vomiting, diarrhea, lethargy, and loss of appetite. A veterinarian may also observe dehydration, fever, and abdominal pain.
These clinical signs, in combination with a positive ELISA test result and abnormal CBC and chemistry panel results, can confirm the diagnosis of parvo in puppies.
It is important to note that early diagnosis and treatment are critical for puppies with parvo. If left untreated, parvo can be fatal.
Therefore, if a puppy is exhibiting clinical signs of parvo, it is important to seek veterinary care immediately.
Treatment Options for Parvo
Parvo is a serious disease that requires immediate treatment. Treatment for parvo is primarily supportive care, which means treating the symptoms while the puppy’s immune system fights off the virus.
The goal of treatment is to prevent dehydration, maintain electrolyte balance, and control secondary infections.
The most common treatment for parvo is intravenous (IV) fluids. This helps to prevent dehydration and electrolyte imbalances.
In severe cases, the puppy may need to be hospitalized and given IV fluids for several days.
Antibiotics are often given to prevent secondary infections. Parvo weakens the immune system, making puppies more susceptible to other infections.
Antibiotics can help to prevent these infections from taking hold.
Intravenous fluids and antibiotics are the cornerstone of treatment for parvo. In addition to these, medications may be given to help relieve vomiting, nausea, and pain.
De-wormer should be given since many puppies also have intestinal parasites that can worsen diarrhea.
In more severe cases, blood transfusions may be necessary. Parvo can cause severe anemia (low red blood cell count), which can be life-threatening.
A blood transfusion can help to replace the lost red blood cells and improve the puppy’s chances of survival.
It is important to note that treatment for parvo can be expensive and time-consuming.
Puppies with parvo often require hospitalization for several days, and the cost of treatment can add up quickly.
However, with proper treatment, many puppies are able to recover from parvo and go on to live happy, healthy lives.
If you suspect that your puppy has parvo, it is important to seek veterinary care immediately. Early treatment can greatly improve the puppy’s chances of survival.
Preventing Parvo in Puppies
Preventing Parvo in puppies is essential for their health and well-being. The following are some tips that can help prevent the spread of this highly contagious virus:
Vaccinations
Vaccinations are the most effective way to prevent Parvo in puppies.
Puppies should receive their first vaccination at 6-8 weeks of age, followed by booster shots every 3-4 weeks until they are 16 weeks old.
It is crucial to follow a strict vaccination schedule to ensure adequate protection.
Disinfectants
Disinfectants such as bleach can be used to kill the virus in the environment.
It is important to clean and disinfect any areas where an infected dog has been, including their bedding, toys, food and water bowls, collars, and leashes.
Collars and Shoes
Parvo can be spread through infected feces, so it is important to avoid walking puppies in areas where infected dogs may have been.
Collars and shoes can also carry the virus, so it is important to clean and disinfect them regularly.
Avoid Contact with Infected Dogs
Puppies should avoid contact with infected dogs until they are fully vaccinated. It is also important to isolate any sick dogs to prevent the spread of the virus.
Regular Check-ups
Regular check-ups with a veterinarian can help ensure that puppies are healthy and up-to-date on their vaccinations.
Any signs of illness should be addressed promptly to prevent the spread of the virus.
The Role of the Immune System
The immune system plays a critical role in protecting puppies from parvo.
When a puppy is exposed to the virus, the immune system responds by producing antibodies that help to neutralize the virus and prevent it from causing disease.
White blood cells are an important part of the immune system. They are responsible for recognizing and attacking foreign substances, including viruses like parvo.
In response to parvo, white blood cells produce antibodies that specifically target the virus.
Puppies that have a strong immune system are better able to fight off parvo. This is why it is so important to ensure that puppies receive proper nutrition and are up-to-date on their vaccinations.
Vaccinations help to stimulate the immune system to produce antibodies that can protect against parvo.
It is important to note that not all puppies develop immunity to parvo after being vaccinated.
Some puppies may not produce enough antibodies in response to the vaccine, while others may not respond at all.
In these cases, puppies may still be susceptible to parvo and should be monitored closely for signs of infection.
Again, the immune system plays a critical role in protecting puppies from parvo.
Puppies with a strong immune system are better able to fight off the virus, while those with a weaker immune system may be more susceptible to infection.
Proper nutrition and vaccinations are important for ensuring that puppies have a healthy immune system and are protected against parvo.
Complications and Long-Term Effects
Parvo can lead to long-term effects that can affect a dog’s health for the rest of their life.
One of the most significant complications of parvo is dehydration. Puppies with parvo often experience severe vomiting and diarrhea, which can lead to a loss of fluids and electrolytes.
This loss can cause dehydration, which can be life-threatening if not addressed promptly.
To prevent dehydration, puppies with parvo may require intravenous fluids to rehydrate their bodies.
Another complication of parvo is shock. As the virus progresses, it can cause a drop in blood pressure, leading to shock.
Shock is a severe condition that can be life-threatening if not treated immediately. Puppies with parvo may require hospitalization and intensive care to manage shock.
Parvo can also lead to secondary infections. The virus weakens the immune system, making puppies more susceptible to other infections.
These secondary infections can be severe and require additional treatment.
In some cases, parvo can cause long-term effects that can affect a dog’s health for the rest of their life. Puppies who survive parvo may experience long-term kidney or liver damage.
The virus can also weaken the immune system, making dogs more susceptible to other diseases.
In severe cases, parvo can lead to death. The survival rate for puppies with parvo depends on several factors, including the age of the puppy, the severity of the illness, and the promptness of treatment.
Hypothermia is another potential complication of parvo. As puppies lose fluids and electrolytes, their body temperature can drop, leading to hypothermia.
Hypothermia can be life-threatening if not addressed promptly. Puppies with parvo may require additional heat support to maintain their body temperature.
