Dog Parvovirus - What You Need to Know

What is dog parvovirus? What are the symptoms of parvovirus in dogs? How can you protect your dog against this deadly condition? Our Oceanside veterinarians explain.

The Spread of Canine Parvovirus 'Parvo'

Puppies and unvaccinated dogs of all ages are susceptible to parvovirus, a highly contagious virus that causes severe gastrointestinal symptoms. Traces of infected dogs' feces spread the virus. Asymptomatic dogs, those who have been infected but have not yet developed symptoms, dogs who have developed symptoms, and those who have recently recovered from the disease can all spread Parvovirus.

Because the disease is so contagious, a person who comes into contact with an infected dog can unknowingly pass the virus on to puppies and other dogs simply by touching them. A loving pat on the head, for example, could be the start of a life-threatening illness.

Other common sources of contamination are leashes, bowls, toys, and bedding.

How Parvovirus Attacks Your Dog's Body

Parvo is a disease that affects the stomach and small intestine. The virus starts destroying the dog's gut barrier, attacking healthy cells and preventing essential nutrients from being absorbed.

Parvo also attacks the bone marrow and lymphopoietic tissues in puppies, which play essential roles in your dog's immune system. In many cases, the virus will also affect the heart.

Why Puppies Are Susceptible to Parvo

If the mother is fully vaccinated against parvovirus the puppies will inherit antibodies from the mother and have dog parvovirus immunity for about the first 6 weeks of their lives. 

However, as the puppies begin to wean at about six weeks of age, their immune systems weaken, and the young pups become susceptible to the disease.

Veterinarians recommend that puppies be vaccinated against Parvo at six weeks of age when they begin to wean and the mother's antibodies are no longer effective protection.

The young dog will not be protected against the disease until they have received all three Parvo vaccinations. Puppies are most likely to contract Parvo during the time between weaning and full vaccination.

Your puppy should receive vaccines against Parvovirus at 6, 8, and 12 weeks. If you are a pet parent, getting your puppy vaccinated against Parvovirus is one of the best ways to guard their health and the health of other dogs in your household and neighborhood.

Symptoms of Parvovirus in a Dog

It's crucial to understand that once your puppy exhibits symptoms, they're already quite ill. If you observe any of the symptoms of the disease, promptly contact your veterinarian.

Parvovirus dog symptoms can include:

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

Treatment for Parvovirus in Puppies

Although Parvovirus cannot be cured in puppies, your veterinarian can provide supportive treatment for symptoms like vomiting and diarrhea. Your dog must receive adequate hydration and nutrition to recover from parvovirus.

Because secondary infections are common in puppies with Parvo (due to their weakened immune systems), your veterinarian will monitor your puppy's progress and may prescribe antibiotics to help combat any bacterial infections that could develop.

If your puppy survives the first four days after symptoms appear, and is treated by a veterinarian, there is a good chance they will recover from the disease. Parvo in dogs usually lasts about a week.

If your puppy is diagnosed with Canine Parvovirus, it is essential to take steps to isolate them from other pets. Always wash your hands thoroughly after being near your young dog.

Preventing Parvo 

Allowing your puppy to be around dogs who have not been fully vaccinated against Parvovirus is never a good idea. While socialization is important for young dogs, it's also crucial to ensure that the dogs with whom your puppy interacts are fully vaccinated and do not pose a health risk. Consult your veterinarian for advice on how to protect your new four-legged family member.

Be sure to follow your vet's advice and have your puppy vaccinated against Parvo, rabies, and other potentially serious conditions based on a puppy vaccination schedule for your area.
