What is the purpose of baseline blood work for a senior dog, and how often is it typically repeated?

• A. To measure heart rate during exercise; repeated weekly.
• B. To assess organ function and establish a reference; repeated annually or more often if conditions exist.
• C. To determine favorite toy; repeated every two years.
• D. To assess fur color; repeated every two years.

Answer: (B)

Baseline blood work is used to evaluate how the dog’s organs are functioning right now and to create a reference point for that individual. This helps the vet detect problems early, even before symptoms appear, and gives a comparison for future tests to see how thingschange over time or in response to meds or anesthesia. It’s not about measuring heart rate, choosing a toy, or fur color. For healthy seniors, the test is typically repeated about once a year. If there are chronic conditions, ongoing medications that can affect organs, or plans for anesthesia, the vet may want to repeat it more often, such as every 6 to 12 months.
