If your dog, especially a puppy, begins exhibiting any of these symptoms, call us immediately.  When parvo is involved, every hour counts.

Please call us immediately if your pet shows any symptoms.

  • Lethargic.  If your dog normally likes to play and has low energy (acts depressed) something is wrong.
  • Lack of Appetite.  The more common strains attack the digestive system.
  • Vomiting with no change in diet.  It usually looks clear and foamy.
  • Bloody Diarrhea.
  • Stronger Feces Odor.  It’s unmistakable and you will never forget it.

Canine parvovirus is the most common serious infectious disease of dogs in the United States. The canine parvovirus or PARVO is highly contagious, can live in the environment for years, and can cause life-threatening disease to dogs, especially puppies.  Fortunately, it can be prevented with an inexpensive vaccination.


Canine parvovirus type 2 (CPV2, colloquially parvo) is a contagious virus mainly affecting dogs. The disease is highly contagious and is spread from dog to dog by direct or indirect contact with their feces.It is also spread through contact with fomites (contaminated objects). Common fomites include hands, instruments, clothing, food and water dishes, toys and bedding. Insects and rodents can also provide a means for disease spread. The virus can remain on a dog’s hair coat and serve as a means of transmission long after recovery from clinical disease. It can be especially severe in puppies that are not protected by maternal antibodies or vaccination. It has two distinct presentations, a cardiac and intestinal form. The common signs of the intestinal form are severe vomiting and dysentery.


The disease is commonly diagnosed by an evaluation of the clinical signs such as lethargy, bloody diarrhea and vomiting accompanied by a laboratory test.


Treatment of parvovirus is directed at correcting the life-threatening dehydration that accompanies the diarrhea and prescribing antibiotics to prevent secondary bacterial infection through the damaged small intestine. In general, if aggressive therapy is initiated early in the course of the disease, the prognosis for recovery can be good. If the disease is diagnosed at an advanced state, fatalities are common.

If your pet is showing symptoms of Parvo please call us immediately.  Early treatment and diagnosis is key! 

We can only take in a very limited number of Parvo cases on a daily basis.  Due to the fact that Parvo is highly contagious, we may ask you not to bring your pet inside our building or allow them to walk around in common areas until we can ensure that we can get your pet directly into an room so that we can protect our other patients.
