Canine Parvovirus (CPV) is a highly contagious viral disease which attacks the white blood cells, the intestinal track, and sometimes the heart muscle. Though CPV infection cannot be transmitted to people or other animals, people and animals can transmit the virus to other dogs. Fecal waste from infected dogs is the main source of infection, and can be transmitted on the hair of feet of infected dogs or through contact with contaminated cages or objects like shoes. Certain breeds are believed to be at a higher risk for CPV infection, including Doberman Pinschers and Rottweillers.

Symptoms of CPV infection typically occur within five to seven days after exposure and can include depression, diarrhea, loss of appetite and vomiting. Vomiting and diarrhea can lead to rapid and serious dehydration. In addition, early symptoms may include loose feces streaked with blood or a light gray or yellow-gray appearance to the feces. Death can occur within forty-eight to seventy-two hours after the first sign of symptoms.
