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.
Puppies are at the greatest risk for parvo between the ages of 6 weeks to 6 months. Puppies can receive their parvo vaccinations at 6, 8 and 12 weeks of age. They must receive a full series of vaccinations to ensure complete immunity. Puppies require a parvo booster vaccine between 14 and 16 weeks of age.
Parvovirus, commonly known as “parvo,” is a contagious virus that can be very serious and even fatal in dogs. Dr. Jennifer Reinhart, a small animal internal medicine specialist at the University of Illinois Veterinary Teaching Hospital in Urbana, explains that parvo is a problem that can be seen in dogs of any age.
Parvo may affect dogs of all ages, but is most common in unvaccinated dogs less than one year of age. Young puppies less than five months of age are usually the most severely affected, and the most difficult to treat. Any unvaccinated puppy that shows the symptoms of vomiting or diarrhea should be tested for CPV.
What are the first signs of parvo in a dog? Initial signs that your dog may have contracted parvo are running a fever, lethargy, lack of appetite, and anorexia. These initial signs may progress and can result in vomiting and diarrhea within two days after showing their first symptom.
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.
Older dogs generally have less severe cases of parvo because their immune system is fully developed and more capable of handling the infection. Being up-to-date on vaccinations will also help a dog combat a parvo infection.
Since parvo is highly contagious, other household dogs can easily become infected if you have a parvo-positive pet. Your cat may also be at risk.
Parvo virus causes severe life threatening diarrhea, often the diarrhea has blood in it. Once a puppy has symptoms of parvo, if left untreated they can die within 48 - 72 hours. It can be simply diagnosed and survival is possible if treated soon enough. If left untreated the mortality rate is as high as 91%.
Your puppy will vomit and have diarrhea if canine parvovirus is present in their system. Vomit may be clear or a yellow or brown color, and diarrhea will often contain blood and be a light yellow or mustard colored hue.
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.
If an older dog does get parvo, it's often a mild case because your older dog has built up a stronger immune system. The parvovirus is everywhere, so over time, your dog will build natural immunity to the virus (whether he's vaccinated or not) by being exposed to it.
Dogs that develop parvo will show symptoms three to 10 days after being exposed. Symptoms include: vomiting, lethargy, diarrhea (usually bloody) and fever. The gastrointestinal tract is where the heaviest damage occurs.
A pet infected with parvovirus may develop a fever and behave lethargically, possibly refusing food within the first few days of infection. Within 24-48 hours, copious vomiting and diarrhea present, often containing blood in the later stages.
The virus usually enters the dog through sniffing or eating infected feces or direct contact with an infected dog. Dogs can shed the virus before they show signs of illness and for several weeks after disease has resolved. Therefore, even dogs that appear healthy can transmit parvovirus.
Washing hands thoroughly with soap and water will remove the virus. Specific disinfectants need to be used to remove parvovirus from the environment, including toys, clothing and cages.
Parvovirus is found in any environment (lawns, homes, kennels, dog parks, etc.) and comes from infected dogs that excrete the virus in their vomit or feces. Puppies are more likely to get parvo because they are more likely investigate everything on the ground.
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%. The mortality rate of dogs with parvo is statistically 10% in adult dogs, and 91% in puppies (Appel et al. 1979; Black et al. 1979).
According to the American Veterinary Medical Association, the best way to prevent parvovirus is through good hygiene and vaccination. Make sure to get your puppies vaccinated, and be sure your adult dogs are kept up-to-date on their parvovirus vaccination.
Parvo is so infectious that humans can spread it unknowingly to other dogs if they have recently come into contact with an infected pup, just by touching them. This means an innocent pat on the head could result in a life-threatening condition.
There is no specific cure for parvovirus, so treatment revolves around supporting the puppy so their body can fight it off. Supportive care for parvovirus generally includes: Hospitalization with intravenous fluids. Antiemetics to stop vomiting.
The virus can live on contaminated surfaces or clothing for up to 5-6 months. Parvovirus becomes widespread throughout the body in 3-4 days.
Adult and older dogs who contract parvo have better chances of survival than puppies. The survival rate of dogs treated by a veterinarian is 68–92%. Dogs and puppies that are diagnosed and treated within 24 to 72 hours following the first symptoms have the best survival rate and in most cases make a full recovery.
What Color Is Parvo Vomit Normally? The color of parvo vomit can vary, so you can't diagnose a dog based on this alone. Dogs with this virus can vomit anything from yellow vomit through to dark brown, and you may even see some streaks of blood in it.
Burch said. “The body may not have produced the appropriate antibodies needed to protect against infection.” Sometimes, your dog's parvo vaccine can be less effective if it wasn't stored properly before he received it. “Vaccine vial handling can also cause a vaccinated dog to contract parvovirus,” Dr.
