It's a virus that was non-existent prior to the 1980s. Now, for most dog owners in Australia, parvovirus is a disease that is part of their pet's regular vaccination regime.
A University of Sydney study has found that canine parvovirus (CPV), a highly contagious and deadly disease that tragically kills puppies, is more prevalent than previously thought with 20,000 cases found in Australia each year, and nearly half of these cases result in death.
How does it spread? Parvovirus is highly contagious and can stay on surfaces and in environments for a long period of time—withstanding heat, cold and humidity. Dogs can contract the virus by interacting with infected dogs, or by coming into contact with contaminated faeces, surfaces or environments.
Canine parvovirus type 2 (CPV-2) is highly resistant and can survive for months in the environment. Studies have observed that if your Fido is not vaccinated, the chances of him getting parvovirus are very high, and the morbidity rate is 100%.
Canine parvovirus is a highly contagious virus that can affect all dogs, but unvaccinated dogs and puppies younger than four months old are the most at risk.
Avoid high-traffic areas, like dog parks, where the other dogs' vaccination and infection status is unknown. The American Veterinary Society of Animal Behavior recommends that puppies have at least one parvo vaccination seven days prior to socialization in safe settings, such as puppy classes.
Parvo can live in the ground, the grass, on bushes – pretty much anywhere (although it is not an airborne virus). Disease prevention is always less costly (and risky) than treating a condition your pet has developed.
Parvo is a preventable disease, but even vaccinated dogs are not 100% protected from the virus.
The best way to prevent parvo is early vaccination. Puppies and younger dogs are most at risk. Symptoms include severe diarrhoea, severe vomiting, lethargy, fever and weakness. Puppies need to be kept isolated from unsafe areas where dogs congregate (such as parks or kennels) until they've completed their vaccinations.
In the U.S., people tend to get infected with parvovirus B19 more often in late winter, spring, and early summer. Mini-outbreaks of parvovirus B19 infection occur about every 3 to 4 years. Since parvovirus B19 only infects humans, a person cannot get the virus from a dog or cat.
Certain breeds and types of dogs appear to have a higher risk of parvovirus infection or show more severe illness once infected. These include Rottweilers, Doberman Pinschers, Labrador Retrievers, German Shepherds, Bull Terrier breeds, and Alaskan sled dogs.
Commonly called “parvo”, the organism is very stable in the environment, able to withstand freezing temperatures and many disinfectants to survive as long as seven months in a contaminated area.
The Spread of Canine Parvovirus 'Parvo'
The virus is spread through traces of feces from infected dogs. Asymptomatic dogs that are infected but aren't showing symptoms can spread Parvo, as well as dogs with symptoms, and those that have recently recovered from the condition.
Products that are effective at killing parvoviruses include Rescue™ (accelerated hydrogen peroxide), potassium peroxymonosulfate (e.g., Virkon® or Trifectant®), calcium hypochlorite (e.g., Wysiwash®), bleach, and sodium dichloroisocyanurate (e.g., Bruclean®).
The first sign of parvo for puppies is often lethargy, lack of appetite, and a fever. Canines will begin to suffer from vomiting and diarrhea as the virus progresses, and can experience dehydration and a high heart rate as a result.
How do dogs and puppies contract Parvo? Parvo can be found in almost any environment. It is transmitted when a susceptible dog comes in contact with the virus. This includes contact with the feces of an infected dog, or objects that contain the virus (shoes, clothes, bedding, bowls, grass, carpets, floors, etc).
Can vaccinated dogs get parvo? Short answer: YES! Some may think once their dog is vaccinated they can't catch Parvo, but the virus has different strains and reinvents itself. So unfortunately, dogs definitely can still catch the parvovirus.
Parvo poop color
The poop should start a pale yellow and gradually become darker as more blood enters the intestines. Parvo poop can go from yellowish brown to dark red, to nearly black in the later stages.
How Long Should I Wait Before Taking My Puppy Outside? Due to potential outdoor biohazards, most vets will advise that pet owners wait until a puppy is at least three months old before taking them outside.
Direct contact isn't necessary for transmission — Because parvovirus can be transmitted via infected surfaces, dog-to-dog contact isn't necessary for infection. The virus can be transmitted to your puppy when she walks on a previously contaminated surface, or from shoes, clothing, or toys brought into your home.
Going Out in the Yard
In mild weather, even newborn puppies can be taken out to your own garden or backyard, as long as they're supervised and confined to a small, safe area. Of course, nursing puppies would likely be taken out along with their mother and the rest of the litter.
This virus is highly contagious and spreads through direct contact with an infected dog or by indirect contact with a contaminated object. Your puppy is exposed to the parvovirus every time he sniffs, licks, or consumes infected feces.
Financial hardships caused by the pandemic have also prevented many pet owners from keeping up with their companions' vaccine protocol. While life has, in many ways, gone back to normal since the early days of the pandemic, parvo cases remain on the rise in many areas.
Despite there being an effective vaccine for the illness, parvo remains fairly common, Dr.
