Generally, a diagnosis is made on the signs of the disease and falling white blood cell counts. Good rapid diagnostic tests are also available at veterinary clinics. Additionally, the virus can be found in the feces by commercial labs using electron microscopy. Treatment for the disease is primarily supportive although recently immunotherapy has become important. Historically, dogs were supported by aggressive intravenous fluid therapy to combat hydration and antibiotics given to reduce secondary bacterial infection.
Food is withheld until vomiting has ceased.
Many veterinarians employ antiemetics to lessen the signs and aid in the control of dehydration. Blood transfusions have been employed to increase the level of globulins, red blood cells and serum protein being lost via the bowel s bloody diarrhea. Most recently, antitoxins and antiparvo serum are showing results. With hospitalization and vigorous support most dogs will survive severe cases of parvo virus. Early detection and aggressive therapy are the key to success.
