FOR BUDOU · ID 001 · THE FIRST ONE. FOREVER.

Some love fades away.
But should never lose its voice.

Budou was Duolink's User #001. When we realized we never truly understood his discomfort, anxiety, and silence — we decided to do something about it:

So every family member can understand what their furry companion cannot say.

Duolink embeds medical-grade vital monitoring and behavioral sensing algorithms into a soft, comfortable woven design. It's not a cold tracker. It's a bridge connecting life and companionship.

The First One. Forever.

— GUARDIAN VALUE —

We don't want to monitor your dog.
We're just afraid of missing out.

After Budou passed, we kept thinking back:

Those unusually quiet nights. Those sudden drops in water intake. Those seemingly ordinary behavioral changes.

If someone had alerted us back then, would the outcome have been different?

And so, Duolink was born.

Detect Anomalies Earlier

Temperature, activity, and hydration trend analysis. When behavior deviates from its own baseline, Duolink logs the first record before you even notice.

Understand Discomfort Sooner

Swallowing and behavioral change detection. On-device AI models locally infer bark types and swallowing rhythms, translating pain and anomalies into a language you can read.

Take Action Sooner

AI risk alerts and family notifications. Strong alerts that override Do Not Disturb, actionable health conclusions, cross-device synced timelines — so love has evidence.

— WOVEN CORE · Invisible Tech Woven into Style —

Technology steps back.
Companionship steps closer.

Hardware exists. But it shouldn't be felt.

Most pet devices feel like electronics. Plastic shells, cold surfaces, bulky structures — eventually forgotten in a drawer.

Duolink chose a different path. We hid the sensors, algorithms, and battery inside a woven structure. What remains is only softness, lightness, and companionship.

Because truly great technology
shouldn't make pets adapt to devices. It should make devices adapt to pets.

— WHAT IF —

What if Budou had been
wearing Duolink.

He couldn't say "I don't feel well."

But his body temperature would have told us.

His activity would have told us.

Every swallow would have told us.

And back then, no one was listening.

So we did one thing — make sure the next Budou is heard.
Emotion Sensing System
— EMOTION SENSING · Hear the Signals That Can't Be Spoken —

You hear the bark.
Duolink tries to understand why.

Dogs express themselves every day. Just not through words.

An unusual silence.

Repeated licking.

Persistent low whining late at night.

A sudden drop in water intake.

These subtle changes often appear before the disease itself. Duolink connects sound, temperature, activity, and behavioral patterns to help families understand: what's happening. Why it's happening. And whether it needs your attention.

01

Hear Emotions

Detect anxiety, excitement, loneliness, and distress signals

Not just counting barks. Combining sound spectrum, activity changes, and temporal context to understand the emotional state behind every expression.

  • Know why they're barking
  • Know when comfort is needed
  • Know if anomalies are persisting
02

See Stress

Discover the anxiety you can't see

Moving house, thunderstorms, being alone, unfamiliar environments. Many dogs endure chronic stress without being noticed. Duolink continuously monitors activity rhythms, rest quality, vocal changes, and temperature fluctuations to build a personalized emotional baseline.

  • Identify chronic anxiety
  • Detect behavioral anomaly trends
  • Proactively adjust the environment
03

Understand Changes

Make every alert evidence-based

A single sensor can misjudge. A single behavior can be coincidental. Duolink cross-validates multiple sensing dimensions and only alerts you when something truly matters.

  • Fewer false alarms
  • Higher confidence
  • Clearer action recommendations
— DUOLINK ECOSYSTEM · A Companionship That Grows Together —

A companionship that grows together.

extending to every important member of the family.

— THE STORY OF BUDOU —

Technology is silent.
Love is louder.

Technology is silent. Love echoes louder.

There are already too many pet devices out there.

They count steps. Track location. Measure temperature. Then push a string of numbers to a phone screen.

But we always felt — that's not companionship.

Because a pet was never a data point to be managed.

They are family. They get happy. Anxious. Scared. And they endure pain in silence.

And the saddest part is: too often, by the time we finally notice something's wrong, it's already too late.

The story of Duolink began with a little dog named Budou.

He was in this world for only 90 days. A malignant disease took him from us.

For a long time after, we kept thinking about one question:

What if we had detected the temperature anomaly earlier.

What if we had noticed the swallowing changes.

What if we had understood those unusual silences.

Would the outcome have been different?

We don't know the answer. But we know — there must be many other families out there, experiencing the same helplessness.

And so, Duolink was born.

Not to make another piece of smart hardware. But to create a new way of understanding.

Let technology step behind. Let companionship step forward.

Let every temperature change be seen. Let every behavioral anomaly be understood.
Let every word that cannot be spoken be heard.

Meet Budou.

Member #001 · The First One.

Budou was Duolink's Member #001. And the original inspiration behind this entire project.

He was only in this world for 90 short days. Yet he made us start thinking —
could we have detected anomalies earlier, could we have better understood companionship.

The 001 nameplate will be permanently preserved.
Never sold. Never replicated.

It reminds us: Duolink was born not because of technology. But because of love.
