Primary Care II Senior Dog Care Exam 2 Practice

In senior dogs, keeping up protection against the diseases that cause the most serious illness is still important, but the plan is adjusted to the dog’s age and risk. Core vaccines, which protect against the most dangerous diseases (the ones dogs are at risk for regardless of location or lifestyle), are continued. Because immune memory from these vaccines tends to be long-lasting, boosters are given at longer intervals—commonly about every 3 years after the initial puppy/adult series—rather than year-round. Non-core vaccines, on the other hand, are selected based on exposure risk: where the dog lives, travel plans, indoor vs. outdoor lifestyle, and potential exposure to certain pathogens. If the risk is low, those vaccines may be deferred or omitted, while the core protections are maintained. This is why the best answer emphasizes continuing core vaccines and spacing intervals longer while tailoring non-core vaccines to exposure risk. Discontinuing all vaccines after age 10 isn’t standard practice, vaccines every 3 weeks regardless of risk isn’t evidence-based, and limiting vaccination to only non-core vaccines misses essential protection against serious diseases.
