As pets grow older, owners increasingly prioritize their health and well-being, aiming to enhance their quality of life. Discussions about extending both the duration and quality of life should begin early, utilizing annual or bi-annual wellness visits to strategize preventive care. When pets are officially classified as seniors, veterinary teams should be ready with established protocols for maintaining their health. Incorporating diagnostic lab work and parasite screenings into wellness routines is crucial for comprehensively understanding and addressing the needs of aging pets.

According to the American Animal Hospital Association (AAHA), senior dogs are defined as being in the last 25 percent of their estimated lifespan, while senior cats are classified as those over 10 years of age. The AAHA 2023 Senior Care Guidelines advocate for regular diagnostic lab tests during wellness exams, recommending a complete blood count (CBC), comprehensive chemistry panel, and urinalysis every six to 12 months, along with annual screenings for ticks and heartworm in dogs, and routine fecal testing for both dogs and cats.
Although some pet owners may be hesitant about the necessity of laboratory testing during wellness appointments, clear communication can enhance understanding. It’s important to explain that assessing patient health requires more than just the pet owner's observations and a physical exam. For instance, while the CBC may seem like a single test, it actually provides a report on 20 to 25 measurements related to the patient’s blood cells, helping identify conditions like anemia, inflammatory diseases, and immune responses.
Similarly, the chemistry panel evaluates multiple organ functions and metabolic processes. Including a urinalysis along with these tests allows for better interpretation of other lab results, providing a clearer picture of the pet’s overall health.
When lab results indicate normal values, veterinarians can affirm these findings, emphasizing the absence of anemia or inflammatory disease, as well as normal functioning of major organs. Celebrating negative results from parasite screenings reinforces compliance with preventive measures and highlights the importance of regular testing.
However, laboratory evaluations can sometimes reveal abnormalities that warrant further investigation. Traditionally, lab results are assessed against broad adult reference intervals, which may not be sensitive to the individual needs of senior pets. Historical lab results from a pet when it was healthy can help create narrower reference intervals, allowing for earlier detection of issues as the pet ages. This proactive approach facilitates timely interventions before problems escalate.
November is designated as National Senior Pet Health Month, emphasizing the year-round significance of senior pet care. By planning in-clinic events and promotions, veterinarians can raise awareness and encourage thorough health assessments.
Defining wellness in aging pets can be complex, as behavioral changes may not always indicate disease. Subtle signs, such as changes in eating habits or hiding, can often be misinterpreted. Routine lab work adds objectivity to evaluations, enabling veterinarians to detect health issues that may not be immediately apparent.
As pets age, the focus shifts from preventive vaccinations to the importance of lab work and infectious disease screenings. Regular laboratory data helps tailor individual patient reference intervals, facilitating the detection of hidden health problems that can affect both pets and their owners due to zoonotic risks.
The findings from these tests provide essential baseline values for monitoring disease progression and inform decisions about pain management and end-of-life care. As pets and their owners share deep bonds, conveying the relevance of laboratory diagnostics can play a critical role in extending both the quality and duration of pets' lives.
