Canine parvovirus (CPV-2) is a highly contagious virus affecting the gastrointestinal tract of puppies and dogs. It is spread by direct dog-to-dog contact, contact with contaminated feces, environments, or people. The virus is resistant to heat, cold, humidity, and drying, and it can survive in the environment for long periods of time. Young puppies and dogs that have not been vaccinated are most at risk for contracting parvovirus. Symptoms of parvovirus include vomiting, lethargy, loss of appetite, and severe, often bloody diarrhea. Death can occur in as little as 48 to 72 hours after onset of symptoms.
Unfortunately, there is no drug that can effectively kill parvovirus, so treatment consists of supportive care with intravenous fluids and drugs to control vomiting and secondary bacterial infection. Treatment for parvovirus is far more expensive than simply vaccinating your pet, and some pets die from parvo despite aggressive treatment.
To prevent parvovirus, puppies should be vaccinated with an effective vaccine starting at 6 weeks of age and again every 3 weeks until they reach the age of 16 weeks. It is very important to complete the puppyhood vaccine series. We see many puppies with parvo that only received one vaccine at 6 or 8 weeks of age. Until your puppy has completed its vaccine series, it is important to use caution when taking your pet to dog parks, grooming or boarding facilities, or puppy classes. Do not allow contact with known infected dogs or their premises.
In short, vaccinate for this deadly disease. We see far too many cases of this easily preventable disease.
