Canine parvovirus recovery times vary depending on the condition of the dog and the severity of the disease. The average hospital stay for treating parvo is five to seven days long, and the survival rate with proper treatment is 70 to 80 percent, according to About.com.
Because there is no cure for parvo, treatment is supportive and typically includes hospitalization and nursing care. During treatment, dogs receive intravenous fluids to help them rehydrate, drugs to stave off nausea and vomiting, antibiotics to prevent sepsis, antacids to avoid additional damage to the esophagus and stomach lining, and deworming medication to eliminate potentially harmful intestinal parasites, notes About.com.
After hospitalization, dogs may require further medication and a prescribed diet. In addition, they shed parvovirus for up to a month after recovery and should be kept away from parks, public areas, puppies and unvaccinated dogs.
