If you’re worried about catching parvo from your furry friend, you can breathe easy. The simple answer is no. Humans cannot catch parvo from dogs. While watching your pet suffer from this serious illness can be heartbreaking, you don’t need to worry about your own health.
Understanding the facts about parvo helps you protect your dog while putting your mind at ease. Don’t wait until it’s too late. Schedule an appointment with AZ Vet Direct today to ensure your dog is properly vaccinated against this preventable disease.
What is parvo?
Parvo, short for canine parvovirus, is a highly contagious viral disease that attacks a dog’s digestive system and immune cells. This dangerous virus primarily affects puppies and unvaccinated dogs, causing severe gastrointestinal symptoms that can quickly become life-threatening. The virus spreads rapidly through contact with infected feces, contaminated surfaces, or even on people’s shoes and clothing. Without prompt treatment, this disease can be fatal, especially in young puppies whose immune systems aren’t fully developed.
What are the signs and symptoms of parvo in dogs?
- Severe, bloody diarrhea
- Persistent vomiting
- Extreme lethargy
- Loss of appetite
- High fever
- Abdominal pain
- Rapid weight loss
- Distinctive odor
Is dog parvo contagious to humans?
No, canine parvovirus is not contagious to humans. The virus is species-specific and only affects canines. While humans can carry the virus on their hands, clothes, or shoes and spread it to other dogs, the virus cannot infect human cells or cause illness in people. There is a human parvovirus B19 that causes Fifth disease in children, but it’s completely different from the canine version. You can safely care for a dog with parvo without worrying about your own health, though you should take precautions to prevent spreading it to other dogs.
4 Risks of Parvovirus in Dogs
Severe Dehydration
The combination of persistent vomiting and bloody diarrhea causes dogs to lose fluids rapidly. This dehydration happens faster than you might expect, especially in small puppies who have less fluid reserves. Without immediate fluid replacement through IV therapy, severe dehydration can lead to shock and organ failure.
Immune System Collapse
Parvo destroys white blood cells in the bone marrow. This leaves infected dogs virtually defenseless against other infections. Secondary bacterial infections often develop, making an already serious situation even more dangerous.
Intestinal Damage
The virus causes severe damage to the intestinal lining, destroying the cells that normally absorb nutrients and water. This damage can lead to a condition called “leaky gut,” where bacteria from the intestines enter the bloodstream. The intestinal damage also prevents proper nutrition absorption, even after the acute illness passes.
Heart Problems in Puppies
In very young puppies infected in utero or shortly after birth, parvovirus can attack the heart muscle. This cardiac form of the disease causes sudden death or chronic heart problems that may not appear until later in life. Puppies who survive often have permanent heart damage that requires lifelong management.
Is parvo in dogs treatable?
Yes, parvo is treatable, but success depends on how quickly treatment begins and the dog’s overall health. With aggressive veterinary care, survival rates can reach 85-90%, though treatment is intensive and often expensive. The key is recognizing symptoms early and getting immediate veterinary attention. While there’s no cure that directly kills the virus, supportive care helps dogs survive until their immune system can fight off the infection.
How is a dog with parvo treated?
- Immediate hospitalization and isolation – Your dog will be placed in an isolation ward to prevent spreading the virus to other patients while receiving 24/7 monitoring
- Aggressive IV fluid therapy – Veterinarians administer balanced electrolyte solutions continuously to combat dehydration and maintain blood pressure
- Anti-nausea medications – Injectable medications help control vomiting, allowing your dog to retain fluids and eventually food
- Antibiotics for secondary infections – Since the disease destroys the immune system, antibiotics prevent bacterial infections from taking hold
- Nutritional support – Once vomiting stops, easily digestible foods are introduced slowly, sometimes through feeding tubes if necessary
- Pain management – Medications help control abdominal pain and keep your dog comfortable during recovery
- Blood or plasma transfusions – In severe cases, transfusions may be needed to replace proteins and antibodies
- Temperature regulation – Maintaining proper body temperature through heating pads or cooling measures as needed
- Continued monitoring – Blood tests track white blood cell counts and other vital signs throughout treatment
How to Prevent Parvo in Dogs
Prevention is always better and less expensive than treatment when it comes to parvo. The most effective prevention method is a proper vaccination schedule, starting when puppies are 6-8 weeks old and continuing with boosters every 3-4 weeks until they’re 16 weeks old. Adult dogs need regular booster shots to maintain immunity throughout their lives. Since this virus is so contagious and can survive in the environment for months or even years, vaccination is your dog’s best defense against this deadly disease.
9 Prevention Tips On Top of Vaccination
- Limit exposure for unvaccinated puppies – Keep puppies away from dog parks, pet stores, and other high-traffic areas until fully vaccinated
- Practice good hygiene – Remove shoes before entering your home and wash hands after being in public spaces where dogs frequent
- Disinfect your environment – Use a bleach solution (1:30 ratio) to clean any areas where infected dogs have been
- Avoid contact with unknown dogs – Don’t let your puppy interact with dogs whose vaccination status you don’t know
- Be cautious at vet visits – Carry small puppies rather than letting them walk on clinic floors, and avoid waiting room interactions
- Quarantine new pets – Keep any new dogs separate from your other pets for at least two weeks
- Maintain yard cleanliness – Promptly remove feces from your yard and dispose of it properly
- Choose puppy classes wisely – Only attend classes that require proof of vaccination from all participants
- Monitor your dog’s health – Regular vet checkups help ensure your dog’s immune system stays strong
Conclusion
While you never have to worry about catching parvo from your dog, protecting your canine companion from this devastating disease should be a top priority. Remember, prevention through vaccination is simple, affordable, and incredibly effective compared to the cost and heartache of treatment.
