The tag that brings them home.
Any phone taps your pet's CAIRN and sees exactly what matters — their photo, their medical alerts, and a one-tap call to you. Editable forever. Powered by nothing.
“The gate was open for twenty minutes before anyone noticed.”
Every lost-dog story starts the same way. What happens in the next hour decides how it ends. CAIRN puts your phone number, your pet's photo, and their medical needs one tap away from whoever finds them — no app store, no account, no reading a worn-off engraving.
Three steps between lost and found.
Tap
Whoever finds your pet holds their phone to the tag. iPhone or Android — no app, nothing to install, nothing to charge.
See
Your pet's page opens instantly: photo, medical alerts in a can't-miss box, personality notes, and your number — exactly as current as you keep it.
Home
One tap calls you. One more shares their exact GPS pin. You get the alert the moment the tag is scanned — before they even dial.
Flip one switch the second they slip out.
A can’t-miss banner with your message — reward, “call any hour”, whatever it takes.
Every scan of a lost pet's tag pings your phone instantly — even if the finder never presses a button.
One tap shares their exact location with you — no phone tag, no “I think I’m near the park”.
Engravings fade. Trackers need batteries.

Trackers find the collar. CAIRN gets the person holding your dog to call you. Plenty of pets wear both.
Fair questions.
Does the person who finds my pet need an app?
What shows up when someone taps it?
What if I move or change my number?
Battery? Charging? Subscription?
How tough is it, really?
What about my privacy?
How much does it cost?
When can I get one?
A cairn is a stack of stones that marks the way home.
CAIRN Pets is a family-run American maker. We grew out of Poppa Prints, our own small-batch manufacturing shop — which means the tag on your pet's collar was designed, printed, chip-embedded, and scan-tested by the same hands that answer your support messages.
We built CAIRN after one too many "the gate was open" scares. Engraved tags go stale the day you move. Trackers die the day you forget to charge them. We wanted the thing hikers trust: a marker that simply points home — no app, no battery, no subscription.
Every tag we print is one more stacked stone on somebody's trail home.
Accessibility matters to us: this site is built for screen readers, keyboards, and reduced motion, and we aim for WCAG AA. If anything is hard to use with your assistive tech, tell us through the contact form — we fix it.
Put CAIRN on your counter, in your kit, or on your feed.
Groomers, vets, trainers, pet boutiques, rescues, and creators — we work directly with the people pets already trust.
