I don't know what do you mean cured by dogs. Dogs can not cure any problems by themselves. Parvo is an viral infection that affects intestine and lymphoid tissues of the dogs. Affected dogs can have bloody diarrhea and vomiting. This condition can cause dehydration leading to death if not treated on time. Virus of parvo is transferred from the feces of infected dogs and contaminated objects.
Treatment of parvo in dogs is only symptomatic that means only vomiting and diarrhea are treated in order to avoid dehydration. Dehydration is managed by giving IV fluid. First 48 hours after the attack of parvo are very crucial because most of the dogs die during this period. In this condition, hospitalization is needed. Vaccination against parvo is also available. It will be good to vaccinate your dog against parvo.
