It's best to consult with your veterinarian to determine the appropriate vaccination schedule for your adult dog based on their health, lifestyle, and risk factors. They may also recommend titers (blood tests) to check for immunity levels, which can sometimes indicate whether a dog needs a booster shot or not.
In summary, adult dogs should not skip vaccinations unless advised by a veterinarian after proper assessment. Regular check-ups will help ensure your dog stays healthy and protected from preventable diseases.
