Canine Longevity
Can we help dogs age better?
For the first time, scientists aren't only studying the diseases of aging. They're studying aging itself.
For generations, we've mostly responded to aging after something went wrong.
The joints become painful. Muscle disappears. The heart changes. Memory and behavior change. Energy declines.
Researchers are now asking a much bigger question.
Lifespan
How many years we get together.
Healthspan
How many of those years they remain healthy, active, engaged and able to enjoy being a dog.
We don't just want more years.
We want more life in those years.
Geroscience
TRIAD
One of the most ambitious questions ever asked about aging dogs:
Can we actually change how they age?
For decades
- Dog gets older
- Age-related problem appears
- Treat the individual problem
Now scientists are asking
- Dog gets older
- What is changing biologically?
- Can those processes be influenced?
- Could that preserve healthspan?
That is geroscience.
What is TRIAD?
TRIAD stands for the Test of Rapamycin In Aging Dogs. It is a research effort connected to the broader Dog Aging Project, and it represents one of the most ambitious attempts yet to investigate whether targeting biological aging can influence lifespan and healthspan in companion dogs.
Its importance is not that it will hand owners an answer next year. It is that aging itself is being treated as something that can be studied directly, with a protocol, endpoints and a control group.
Why dogs?
Dogs age faster than we do, which means a study can follow a meaningful portion of a life without waiting decades.
They also age in ways that rhyme with ours: joints, heart, muscle, cognition and cancer risk all change over time.
Why companion dogs matter
Laboratory animals live in controlled, uniform environments. Companion dogs live in our homes, sleep on our floors, eat different food, get different amounts of exercise and breathe the same air we do.
That messiness is the point. It is much closer to the real world any future recommendation would have to survive.
What is rapamycin?
Rapamycin is a small-molecule drug, not a peptide. It acts on a nutrient-sensing pathway that appears repeatedly in aging research across species.
Because it is not a peptide, it never appears in our Peptide Science section. It belongs here, in geroscience.
Nothing on this page is a suggestion to obtain or give any drug to a dog. This is research education.
What are researchers measuring?
Study designs in this field look at things like heart function, cognitive measures, activity, body composition, blood-based markers, disease occurrence and survival over time.
Measuring aging is itself an unsolved problem, which is part of what makes the work difficult and interesting.
What is healthspan?
Healthspan is how many of a dog's years are spent healthy, active, engaged and able to enjoy being a dog.
What is lifespan?
Lifespan is simply how many years we get together. It is the easier number to count and the smaller half of the story.
What could we learn?
Whether biological aging in dogs responds to intervention at all.
Which measures actually track meaningful change over years.
How much variation between dogs comes from genetics, environment and daily life.
Why this could change how we think about aging dogs
If aging processes can be measured and influenced, then "they're just getting old" stops being the end of the conversation.
We take no position on the eventual results. We are following the work, and we will describe what it finds rather than what we hope it finds.
The Dog Aging Project
Thousands of dogs.
One enormous question.
Why do some dogs age better than others?
Rather than testing one compound, this work follows large numbers of companion dogs over time and studies what actually differs between them.
Genetics
Why breed and family history shape how a dog ages.

But they may also have a biological age.
Two dogs can both be ten years old on the calendar while their bodies may not necessarily be aging at exactly the same rate. Researchers studying canine epigenetic clocks look at chemical marks on DNA that change in patterns over time, and ask whether those patterns can estimate biological aging rather than simply counting years.
Chronological age
Years since birth. Easy to know, and the same for every dog born on the same day.
Biological age
An estimate of how the body itself is aging. Still an active research question in dogs, not a finished consumer test.
The future of canine longevity
Different fields, one shared goal
Helping dogs live healthier for longer.
There probably won't be one answer to aging.
- TRIAD is investigating one approach.
- Peptide researchers are investigating others.
- Mitochondrial researchers are studying cellular energy.
- Epigenetic researchers are studying biological age.
- Regenerative researchers are studying repair.
- Neuroscientists are studying cognitive aging.
- Muscle researchers are studying physical resilience.
- Pawformance Labs follows all of them.
We follow the science wherever it leads.
Because our dogs are worth the journey.
Science is the tool. Love is the reason.
We aren't interested in longevity because we want a number on a chart to get bigger.
We care because there's a dog sleeping beside someone's bed tonight.
A dog waiting by the door.
A dog who still gets excited when they hear the word "walk."
A dog whose face has gotten gray but whose place in the family hasn't changed at all.
Their golden years are priceless.
And if science can teach us how to make more of those years good years, we believe that's worth exploring.
More good days.
More good years.
More time together.
