Healthspan, Lifespan, and the Question TRIAD Asks

Two numbers, one question

Lifespan is how many years we get together. Healthspan is how many of those years a dog spends healthy, active, engaged and able to enjoy being a dog.

They are not the same number. A dog can live a long time while spending much of it in decline. They can also have a shorter life that is almost entirely good. Most owners, if asked, would trade years for quality — but the goal of course is both.

The shift TRIAD represents

For most of veterinary medicine, aging has been something you respond to after something goes wrong. The joints become painful, the heart changes, memory fades — and each problem is treated as it appears.

TRIAD, and the broader field of geroscience, ask a different question: what if those problems share something deeper? What if the underlying biological processes of aging could be measured, understood, and eventually influenced — so that decline arrives later and more slowly?

That is the shift from *treating diseases of aging* to *studying aging itself*.

What the benefits could look like

If TRIAD demonstrates that aging processes in dogs can be influenced, the downstream benefits could include:

• More good years — not just more years, but more years where a dog can still walk, play, think and engage
• Slower cardiac decline — preserving the heart function that keeps a dog active
• Preserved mobility — keeping dogs on their feet and moving comfortably for longer
• Cognitive preservation — holding onto the mental sharpness that makes a dog feel like themselves
• Extended lifespan — the hardest and most consequential endpoint

These are the outcomes the trial is designed to detect. None of them is a result yet.

Why this is hard

Measuring aging is itself an unsolved problem. Two dogs born on the same day may age at different rates, and there is no single number that captures how a body is doing the way a calendar captures how long it has existed.

That is why TRIAD follows many dogs over time and measures many things. The messiness of real life — different breeds, different homes, different food, different activity — is the point, not an obstacle. It is much closer to the real world any future recommendation would have to survive.

The honest position

We take no position on the eventual results. We are following the work because the question matters, and we will describe what it finds rather than what we hope it finds.

If aging processes can be measured and influenced, then "they''re just getting old" stops being the end of the conversation. That alone — regardless of what TRIAD specifically finds — would change how we think about the dogs we love.
