Parvovirus in Dogs: What You Need to Know

Parvovirus is a highly contagious and dangerous virus for dogs. It spreads through contact with infected dogs or their belongings, such as toys, bowls, or leashes. In this post, our vets in Cincinnati will cover everything you need to know about parvovirus and how to keep your furry friend safe.

How Canine Parvovirus ('Parvo') Spreads

Parvovirus is an extremely contagious virus that severely sickens puppies and unvaccinated dogs. It spreads through fecal matter from infected dogs. Even asymptomatic dogs and those without visible symptoms can still transmit the virus, as can dogs with symptoms and those who have recently recovered from the virus.

The virus is so contagious that simply touching an infected dog, even if you don't know it's infected, could make puppies and other dogs sick. This means that a seemingly harmless pat on the head could lead to a life-threatening illness.

Objects such as leashes, bowls, toys, and bedding can also carry the virus and infect other dogs.

How Parvovirus Attacks Your Dog's Body

Parvo is a disease that mainly affects dogs' stomachs and small intestines. The virus starts destroying the barrier of the dog's gut by attacking healthy cells and blocking the absorption of essential nutrients.

It can also harm the bone marrow and parts of the immune system in puppies, sometimes leading to heart problems. 

Why Puppies Are More Susceptible to Parvo

When a mother dog is fully vaccinated against parvo, her puppies will inherit antibodies from the mother. These will keep them safe against the virus during the first six weeks of their lives, temporarily giving them parvovirus immunity.

However, at about six weeks of age, the puppies start to wean, and their immune systems weaken, making them susceptible to the disease.

Veterinarians recommend starting parvo vaccination for puppies at six weeks of age when the puppy starts weaning and the antibodies from the mother are no longer there to keep it safe.

It's important to note that your young dog will not be protected against the disease until they've received all three parvovirus vaccines and boosters. Those puppies are most likely to catch parvo during the gap between weaning and full vaccination.

Your puppy should get parvovirus vaccines at 6, 8, and 12 weeks. If you are a pet parent, vaccinating your puppy against parvovirus is one of the best ways to protect your new friends and other dogs' health in your home and neighborhood.

What are the symptoms of parvovirus in dogs?

It is crucial to understand that once your dog displays symptoms of parvovirus, they are already very ill. If you observe any of the symptoms listed below in your puppy or dog, contact your vet right away.

  • Weight loss
  • Loss of Appetite
  • Depression
  • Lethargy
  • Dehydration
  • Weakness
  • Fever
  • Bloody diarrhea
  • Vomiting

Treating Parvovirus

Parvovirus has no cure, although your vet will offer supportive treatments to help with symptoms such as vomiting and diarrhea. It is important to ensure your pup receives adequate hydration and nutrition to recover from parvovirus.

Puppies with parvo are prone to other infections because of their weakened immune system. Your vet will monitor your puppy's ongoing condition and might prescribe antibiotics to combat any bacterial infections that may arise.

They can recover if your dog receives veterinary care and survives the first four days of symptoms. Typically, dogs take about a week to bounce back from parvo.

Suppose your puppy is diagnosed with canine parvovirus. In that case, you must take the proper steps to isolate them from other animals and always thoroughly wash your hands after being around your dog.

How to Prevent Your Dog From Contracting Parvovirus 

Ensure your puppy only plays with dogs fully vaccinated against parvovirus. Your puppy needs to socialize, but it's also crucial to ensure that the dogs your puppy hangs out with are healthy.

Talk to your vet to keep your new furry family member safe. Follow your vet's recommendations and make sure your puppy gets vaccinated for parvo, rabies, and other important diseases according to your local vaccination schedule.
