The research

Your activity contributes to science.

All opted-in user data contributes to research about how to radically extend canine longevity. Sharing is opt-in in settings, and the app works the same either way.

What helps our research

Four everyday signals, one longevity picture.

Aging shows up in how a dog moves, how a dog carries weight, what a blood panel reads, and what a dog takes day to day. We track all four.

Every walk

A walk records real activity, the part of a dog's life that veterinary records never captured. Route, pace, and active minutes, from the walk you were taking anyway.

Photo check-ins

A photo reads body condition over time, one of the most studied signals in how dogs age. You confirm every read, and the picture builds as your dog does.

Lab-validated bloodwork

When you are ready, a real blood panel goes to your dog's vet to review, and the lab validates the values. That is what makes a longevity read sharp instead of rough.

Your dog's record

The record holds what your dog actually takes, food, supplements, and vet-prescribed medications, alongside weight over time. You log it, and your vet can add to it.

Your vet reviews the panel and reads it against the report in front of them. The lab validates the data. The score stays ours to compute, and the care stays with your vet.

How your dog helps

Every walk is a data point.

A decade of anecdotes becomes evidence when enough dogs are tracked the same careful way. Every walk, weight, and panel is one more real day in a picture that veterinary records never held.

Sharing your dog’s data for research is opt-in, in settings, and the app works the same either way. It earns no points and no badge. It is a gift, freely given, and that is exactly what makes it good science.

We publish what we learn in the open, and not only the flattering parts. Anyone can read the work as it comes.

Where it’s going

As new treatments arrive, we track them.

Aging science is having a moment: rapamycin trials in dogs, longevity drugs reaching real clinics, and new supplements and diets arriving every year. This is the most alive that canine medicine has been in a long time.

As each one arrives, Tailmates tracks how it fits with everything else we hold: activity, body condition, bloodwork, and what dogs actually take. That is the question worth answering, how it all works together, for one specific dog.

Naming the frontier is not a recommendation. What a dog should take is a conversation with your vet, always. Tailmates informs; your vet decides.

Where we’re at

Where the score stands today.

The longevity score is a transparent calculation, anchored to published veterinary life tables and shown as a range rather than a date. Every number is one you can check, and a lab-verified score adds a real blood panel your vet reviews.

As the pack grows, outcome tracking begins, and the score moves from a read of published research toward a read tuned on dogs. That is the road ahead, and it is the whole reason to track a dog carefully today.

We publish what we learn as it comes, whether the result is good, boring, or surprising.

Our papers

Both papers behind the score are public.

Both papers describing how the score works are posted on Frontier Science, the founder’s open-science journal, as editorial previews. They are early drafts, not peer reviewed yet, and we update the model they describe as real data comes in. You can read them yourself.

The ask is simple.

This part is a gift, freely given. Sharing your dog’s data for research is opt-in in settings, turning it on earns you no points and no badge, and the app works the same either way.

Walk your dog. That is the whole ask.

Read the mission this belongs to.

The score you see today is educational and built for everyday wellness. Your veterinarian leads the medicine and knows your dog; the score is here for the ordinary days in between.
