Our mission

Walk more. Live longer. Together.

More good years with the dog you love

Dogs live shorter lives than we do, and the single biggest lever most of us have is also the simplest: the daily walk. Tailmates exists to make that walk something you and your whole pack want to do every day — and to turn all that movement into proof your dog is getting healthier.

Why Tailmates

The walk is the habit. Longevity is the payoff.

Most health apps ask you to start something new. Tailmates wraps a game around something you already do. Every walk earns points, grows a streak, levels up your pack, and quietly feeds your dog’s health — so showing up tomorrow feels less like discipline and more like play.

Underneath the game is the part that matters most: a vet-backed longevity score that shows the good years you’re adding. Not a grim countdown — a hopeful, gain-framed signal that climbs as your dog gets healthier. The game gets you out the door. The score shows you it’s working.

And you’re never doing it alone. Tailmates is built for packs — friends, your dog park, your neighborhood — because the surest way to keep walking is a few good companions pulling you back outside.

How it works

One simple loop, every single day

Walk → points → your dog thrives → a longevity insight you can watch improve. Then tomorrow, you do it again.

  1. 01

    You walk

    Hit start and walk your dog like you already do. The same fifteen minutes around the block — now it counts for something.

  2. 02

    You earn points

    Distance, streaks, levels, leagues, and packmates cheering you on turn a daily chore into a daily win you actually look forward to.

  3. 03

    Your dog thrives

    Those walks compound. Healthy weight, steady activity, a stronger heart — the quiet, daily work of a longer, better life together.

  4. 04

    You see the longevity insight

    Tailmates turns it all into a longevity score that shows the good years you're adding — and, with your vet, becomes a clinically Verified one.

The science, honestly

Hopeful, but never overclaiming

We’re optimistic about what daily movement does for a dog’s healthspan — and we’re careful about what we claim. The free score is a wellness estimate, not a diagnosis. The clinical truth comes from a vet, in the loop, every time.

That line is the whole point. Software is free and gets you moving; a licensed veterinarian provides the one thing software can’t — the medical sign-off. No Verified score exists without one.

What the longevity score is — and isn’t

  • The free Longevity Estimate is a wellness signal built from breed and actuarial life tables, body condition, and the real activity you log — not a medical test.
  • It is always shown as a range, never a single date, and it is framed by the good years you can add, not a countdown.
  • It does not diagnose, treat, or prevent disease, and we never sell supplements or promise outcomes.
  • A score only becomes Verified after a licensed veterinarian reviews real bloodwork inside an established veterinarian-client-patient relationship.

Start a streak worth keeping.
