**7. Conclusion**

CPV-2 is one of the most significant viral enteropathogens of canines causing high morbidity and mortality and manifested by vomition and severe acute haemorhagic gastroenteritis. Prompt symptomatic therapy will increase survivability of infected puppies but vaccination is best way to prevent the disease in dogs. Despite the pups are protected through vaccination from the pregnant bitch, it is more vulunerable to CPV-2 infection as maternal antibody titers started declining. Despite the availability of high sensitive and specific diagnostic approaches and the effective prophylactics such as modified live virus and inactivated vaccines, a large number of outbreaks are still reported in wide geographical areas across the globe in both vaccinated and unvaccinated dogs. The future studies should be taken up towards vaccination failures, occurrence of CPV-2 in different canine species and the emergence of antigenic variants of the CPV-2 involved in the outbreaks.
