Yes, vaccinated dogs can still contract parvovirus, but the risk is significantly reduced. The effectiveness of the vaccine depends on several factors, including the dog's age, health status, and the timing of the vaccinations. Puppies typically receive a series of parvo vaccinations starting at six weeks of age, with boosters given every three to four weeks until they are about 16 weeks old. It is essential to ensure that your dog receives all the necessary vaccinations and boosters to provide the best protection against parvo. Additionally, some dogs may not develop full immunity even after vaccination, especially if they were exposed to the virus before completing their vaccination series. Therefore, it's crucial to monitor your dog's health and avoid exposing them to high-risk environments, such as dog parks or places where unvaccinated dogs frequent, especially during their early months.
