Parvo Virus & Vaccines

 Your new Portuguese water dog puppy will come with one set of puppy shots, this Vaccine includes - Canine Distemper-Adenovirus, Type 2-Parainfluenza and Parovirus Vaccine. Just like with children the shots cannot be given all at once and must be done in a series of 3, each one being approx. 4wks apart. I usually start puppy shots at 7wks, so the new owner will have to take the pup back at 11wks and again at 15. At this time your puppy will also be given the Rabies* shots. I strongly believe that you should get the one year booster and then go every three years after that.

Even though your new pup has been vaccinated for Parvo, one shot does not make them ammune, they infact can still get the virus. Its with this in mind that I recomend that you stay clear of parks and wooded areas. Instead think of your yard as a safe zone, going for walks on the sidewalks are safe as the ultra violet from the sun will kill the virus. Your pup is a baby and should be on a leash for its safety, a good play in the yard and a walk down the street are good enough exercises for now.

(*You can do your own research but I suggest that Rabies & Vaccines be done every 3years, there are many articles about over vaccinating our pets. try this link )

Parvo - A Dangerous Canine Virus

Shirley Greene

Canine Parvovirus (CPV), commonly referred to as Parvo, is a very serious viral disease in dogs. This illness first appeared in about 1978 and there was a widespread epidemic in dogs of all ages. As no dogs had been exposed or vaccinated at that time, dogs of all ages died from this infection. Veterinarian researchers believe that canine Parvovirus is a mutation from the feline Parvovirus, also known as feline distemper virus. Parvo has adapted over time and new strains have appeared. The good news is that the current vaccinations available protect against all strains.

Three Types of Parvo

  • Asymptomatic - where the dog has no signs of having the disease. This is common in dogs over 1 year old and dogs previously vaccinated.
  • Cardiac - this form of the disease has virtually been eliminated by immunization of bitches prior to having puppies. Before a vaccine was available, infected pups, under 3 months, would have severe inflammation, necrosis (death) and scarring of the heart muscle. Although rare, it may still occur, leaving a pup with chronic congestive heart failure, often leading to death in weeks or months.
  • Intestinal - this is the form of the virus most commonly seen today. It causes extreme damage to the lining of the digestive tract. Parvo likes to grow in rapidly dividing cells and the intestinal lining has the biggest concentration of rapidly dividing cells in a puppy's body. The virus attacks and destroys certain portions of the absorptive villi, the intestinal crypts. And, even with this form of Parvo, heart muscle damage may also occur.


  • Loss of appetite
  • Lethargy
  • Diarrhea, often bloody
  • Vomiting
  • High Fever
  • Foul smelling, liquid yellow stool

Parvovirus causes severe life-threatening illness, through dehydration, acid-base imbalance, infection and shock. If you suspect your pet may be infected, it is an emergency and you should contact your veterinarian immediately.

How is it transmitted?

Parvo is carried by dogs. Adult dogs may be infected carriers and not show any signs. Dogs with the typical symptoms and diarrhea shed the virus perhaps for as long as 7 days after the symptoms have ended. Generally, it takes 3 to 10 days from the time of exposure for symptoms to appear and for your dog or pup to test positive. The onset of clinical signs is usually sudden, within 12 hours, or even less.

The Parvovirus is particularly long-lived in the environment, lasting anywhere from 1 to 7 months, or even longer. Due to the large amounts of virus particles shed in the feces of an infected dog and the ability of the virus to survive, complete eradication of the virus is often impossible.

Parvovirus is specific to canines and cannot be spread to humans or other pets of a different species, such as cats.

Parvo may be brought home to your pup on shoes, hands and even car tires. It is not an airborne illness. So, even if your dog or pup does not leave your yard, they may contract this disease. Therefore, it is vital to immunize your dog and also follow appropriate disinfecting procedures listed under Prevention.


In all but mild cases, treatment requires hospitalization and intensive management is essential. There is no magic drug to kill the virus and the patient requires supportive measures, which may include:

  • intravenous fluid replacement to combat dehydration and control electrolyte levels
  • medication to control vomiting and diarrhea
  • antibiotics to prevent secondary bacterial infections
  • blood transfusions - to replace protein loss, provide antibodies, help with anemia

If your pup survives the first 3-4 days, it will usually live. Dogs that recover are immune to the disease.

After your dog recovers completely, it should be isolated for at least 2 weeks and some resources advise isolation for as long as 30 days. This is in order to minimize spreading the virus.

Preventing Parvo

Preventing Parvo in your dog is a two-step approach:

Vaccinating your puppy and keeping your adult dog up-to-date with regular booster shots can prevent Parvovirus. Consult your veterinarian to determine an appropriate inoculation schedule.

And secondly by not letting a puppy wander in parks/woods, this virus can live on the ground for up to 2 years, so even though you don’t see other dogs, it could still be there. 

Your puppy is young and just walking on the sidewalk (the ultra violet kills parvo) and playing in your yard are enough right now.
