Abstract

Background: Canine parvovirus (CPV) disease is highly contagious and primarily affects young, unvaccinated dogs. It can cause severe bloody diarrhea or vomiting and high mortality rates.

Objectives: To assess the prevalence, breed distribution, and vaccination status of CPV cases, and to evaluate factors associated with CPV positivity among dogs in Cebu, Philippines.

Methods: This retrospective analytical study covered suspected and confirmed CPV cases tested with commercially available test kits in Cebu, Philippines, from 2018 to 2024. Clinical records from participating veterinary facilities were examined. Qualifying cases were processed, coded, and imported into a statistical software for further analysis.

Results: A total of 1,014 cases were studied, of which 72.7% of the dogs tested positive for CPV. Breed susceptibility varied, with Shih Tzus and mixed breeds exhibiting higher positivity rates. Vaccination appeared to significantly reduce the risk of CPV, as unvaccinated dogs had higher infection rates than vaccinated dogs. The statistical analysis indicated that younger dogs with incomplete vaccination were more likely to be CPV-positive.

Conclusion: The findings underscore the importance of vaccinating puppies, conducting targeted public awareness campaigns, and enhancing veterinary services to mitigate CPV incidence. Future research may investigate seasonal variations, environmental factors, and long-term immunity in recovered dogs to develop better disease prevention strategies.
