Veterinary Teams Should Start Quality-of-Life Scales Sooner

Most veterinary teams reach for quality-of-life scales only after a senior pet develops progressive disease, treatment options narrow, and a family asks: "How will I know when it's time?" The 2023 AAHA Senior Care Guidelines and a growing clinical argument suggest that first assessment should happen months or even years earlier, while the pet is still doing well.

November is Senior Pet Month, and the case being made to practices is not about swapping tools. It is about timing. Introduced early, QOL scales create an individualized baseline, help families recognize meaningful change sooner, and turn future-care planning into a routine part of senior medicine rather than a conversation held during a crisis.

Why the baseline matters while good days are plentiful

The 2023 American Animal Hospital Association Senior Care Guidelines state that senior care cannot follow a one-size-fits-all approach and must consider the individual patient's health, function, environment, and family. The same principle governs QOL assessment.

One dog's good day may include a morning walk, stationing at the kitchen counter, and greeting family at the door. Another's may mean sleeping most of the day but still brightening when the leash appears. A cat's meaningful activities might include grooming, jumping onto a favorite chair, or watching birds from the same window each afternoon.

Senior visits can capture this picture with three questions:

• What does a really good day look like for this pet?
• What are 3 to 5 things the pet loves to do?
• What changes has the family noticed over the past 6 months?

The answers establish what "good" looked like before chronic disease, pain, cognitive decline, or frailty changed the picture. That record is surprisingly difficult to reconstruct later.

What should teams track — a score or a trend?

Several validated instruments exist. The HHHHHMM scale, described by Villalobos in 2011, evaluates hurt, hunger, hydration, hygiene, happiness, mobility, and whether good days outnumber bad. Owner-reported tools such as the Canine Brief Pain Inventory and the Liverpool Osteoarthritis in Dogs (LOAD) questionnaire assess pain and mobility; LOAD's construct and criterion validity were evaluated by Walton and colleagues in a 2013 study published in PLoS One.

The value lies not in a single number. One score is a snapshot; repeated assessments build a timeline. Because caregivers see their pets daily, gradual decline is easy to miss. A dog does not suddenly lose the walk he enjoyed a year ago — the route shortens over time, stairs go unused, the car jump hesitates, the door greeting goes unslept through. Any one change invites the rationalization of "just getting older." Viewed longitudinally, the same changes may reveal decline in mobility, comfort, cognition, or engagement.

Regular assessment gives the veterinary team and the family a shared language for recognizing those trends.

Does a falling QOL score mean the pet is dying?

Not necessarily, and the association is itself a clinical problem. When QOL tools appear only at end of life, clients may link them to euthanasia and avoid the conversation out of fear of what a declining score means.

A change in QOL indicates that something has changed — often something treatable:

• A dog that no longer wants to walk may have inadequately controlled osteoarthritis pain.
• A cat that stops jumping onto the bed may benefit from pain assessment, environmental modifications, or both.
• Changes in sleep, interaction, housetraining, or anxiety warrant evaluation for cognitive dysfunction.
• Decreased appetite or grooming may reveal an undiagnosed medical problem.

The AAHA guidelines explicitly state that senior care is not limited to sick pets and includes proactive attention to pain, cognition, nutrition, behavior, mobility, and environment. Longitudinal QOL assessment becomes clinically useful as a way to identify where the team can still improve a pet's life, not merely document its decline.

How does early assessment change end-of-life planning?

As a senior pet's needs increase, QOL conversations can become progressively more specific, without asking a family to decide today what they will do months from now. With progressive disease, the discussion can address which clinical signs should prompt a call, what constitutes an emergency, where the family should go if the pet deteriorates overnight, whether hospitalization aligns with their goals, and when the focus might shift from disease-directed treatment toward comfort.

Eventually, planning may cover hospice preferences, location of euthanasia, and aftercare, all documented in the medical record. Families who have worked through these questions in advance face a crisis with less panic and uncertainty; they are not weighing every end-of-life decision for the first time.

QOL tools will keep their place in hospice and euthanasia decisions. The shift being urged for Senior Pet Month is that they also function as ordinary senior-medicine instruments — establishing what a good day looks like while good days are plentiful, and revisiting that picture over time. Then, if a family eventually asks how they will know it is time, the conversation does not start there; the team and the family will have been asking "How is this pet doing today?" all along.
