How does the pet tag help if my pet gets lost?
Each pet can have a QR code tag for its collar. Whoever finds your pet scans it with a phone camera and sends you a message, without an app and without seeing your name, address or your pet's history. If your pet goes missing, mark it as lost and VetVitae walks you through lost mode and a poster with the same QR code.

- Open your pet, tap ⋯ and choose Share and tag.
- Under Pet tag, tap Create tag.
- Choose Round tag · 3 cm or Sticker · 5 cm.
- Tap Print for an A4 sheet of tags to cut out, or Save image to print it elsewhere or engrave it.
- Under What the page shows, choose what else a finder sees.
What does a stranger see?
By default, only your pet's photo and name, "If you found me" and Send a message to my family. You choose what else, under What the page shows:
- A phone number, with Call and WhatsApp buttons. You type it on the tag; it is not taken from your account. It shows only while your pet is lost, unless you tick Show it even when Luna isn’t lost.
- Needs medicine daily. The page says "I take medicine every day", never which medicine.
- Allergies, from your pet's profile.
- Microchip number, from your pet's profile.
- A note from you, up to 120 characters, like "Very shy, don't chase".
Never shown: your name, email or address, your pet's history, or your other pets. Live preview shows the page exactly as a finder will see it. Each change saves on its own.
How does a finder's message reach me?
A finder writes a message, and can add their phone and share their location. You and everyone who shares your pet get it in VetVitae:
- In the notifications, as "Someone found Luna".
- On Home, as a card with the message, a map of where they were, Call finder and Directions.
- On the Share page, under Messages, for 90 days.
The finder doesn't need the app or an account. Messages arrive in the app's notifications; your phone doesn't ring for them, so open VetVitae often while your pet is missing.
What do I do when my pet is lost?
Mark your pet as lost. VetVitae walks you through four short steps, nothing in them is required, and you can change any of it later from your pet's Overview.
- Open your pet, tap ⋯ and choose Change status.
- Choose Lost and tap Next. Let’s get Luna home says what happens next. Tap Start.
- Under When and where was Luna last seen?, set the Date, the time if you know it, and Last seen around: a street, a square or a landmark, or tap Use where I am now. What happened and Wearing are only for your family. Tap Next.
- Under What should a finder know?, choose what the tag page shows, like a phone number. Tap Mark Luna as lost.
- Under Now spread the word, print the poster, share its image or copy the page link. Tap Done.
From then on the tag page says "I'm lost" first, and every scan shows in your notifications. If your pet has no tag yet, marking it lost makes one, so the poster always has a QR code that works. Your pet stays in your active pets with a Lost badge, and medicine reminders keep going. Routines pause.
What does the Overview show while my pet is lost?
The Overview leads with Luna is lost, since when and where, with Share alert to send the poster image and Emergency card. Under it:
- From Luna’s tag: the last three messages from finders since your pet was lost, with Call finder and Location, and how many times the tag was opened.
- Search kit: Print poster, Share again, Add more details for the phone, medicine and note on the tag, and Where Luna was seen to update the place and time.
- Luna is home, for when your pet is back.
People who only view your pet see the lost alert with Emergency card, without the messages or the search kit.
How do I make a lost poster?
Tap Print poster in the last step of the lost flow, or under Search kit on the Overview. The Share page also has Make a poster while lost mode is on. The poster has your pet's photo and name, since when, where it was last seen, the phone if you added one, and the tag's QR code.
- In color or Saves ink, for printing in black and white.
- Tear-off strips, on by default, adds tabs at the bottom, each with your phone, or the tag's address when there is no phone.
- Share image sends it to neighborhood groups through your phone's share sheet.
- Print A4 makes the poster to print, with the phone as its biggest line.
Scans and messages from the poster reach you the same way as from the tag. Calling nearby vets and shelters helps too, in case someone brings your pet in to scan the microchip.
What do I do when my pet is home?
Tap Luna is home at the end of the Overview, or on the Someone found Luna card on Home. You can also open the pet's ⋯ menu, tap Change status and choose Active. Lost mode turns off, the tag goes back to how it was, and the phone hides again unless you chose to always show it. Routines pick up again, and messages from this loss stop showing on Home and the Overview.
How do I replace or turn off a tag?
Both are at the bottom of the tag on the Share page.
- Replace tag makes a new code. The QR on the old tag stops working right away, and your settings and messages stay. Use it for a lost collar or a tag you gave away. Print the new one before your pet goes out.
- Turn off tag stops the page. Anyone who scans the old tag sees "no longer available". Messages stay for their 90 days, and you can make a new tag later.
What to know
- A tag never expires. It works until you replace it or turn it off.
- The Share page shows how many times the tag was opened. While your pet is lost, every opening also shows in your notifications, with nothing about who opened it.
- Messages are deleted after 90 days, with the finder's phone and location. Openings of a lost pet's tag are kept 7 days.
- When and what happened, and what your pet was wearing, stay with your family. They never show on the tag page or the poster.
- Fish have no tag. People who only view your pet can't see the tag or its messages.
Questions
Does the tag expire?
No. A tag is printed on something physical, so it works until you replace it or turn it off. Vet links expire; tags don't. If a collar with the tag is lost or given away, tap Replace tag on the Share page: the old QR stops working right away and you print the new one.
Does the person who finds my pet need the app?
No. Any phone camera opens the tag page in the browser, with no app and no account. From there they can call you, if you added a phone, or tap Send a message to my family, write a message, and add their phone and location if they want.
Is my phone number shown on the tag?
Only if you add it. The tag starts with no contact at all, and finders reach you through messages. When you add a phone, it shows only while your pet is marked lost, unless you tick Show it even when Luna isn’t lost. The number is typed on the tag, so you choose which one goes public.
Can someone spam me through the tag?
It's limited. Messages can't contain links, are capped at 500 characters, and each connection can send only a few messages an hour. Your name, email and address never show on the tag page. If a tag gets misused, tap Replace tag to change its code.
Will my phone ring when someone sends a message?
Yes, in the iPhone and Android apps, once you allow VetVitae's notifications. Each message rings your phone with what the finder wrote, and tapping it opens the tag. Everyone who owns the pet with you gets it too. On the web, messages show in VetVitae's notifications and as a card on Home. Add a phone on the tag as well, so finders can call you directly.
Can I order a physical tag?
Not from VetVitae. Print the tag yourself: tap Print for an A4 sheet with dotted cut lines, or Save image to take the QR code to a shop that engraves or prints tags. Choose Round tag · 3 cm for the collar or Sticker · 5 cm for a carrier or a crate.
Who sees the messages?
You and everyone who shares your pet as owner or co-owner. People who only view your pet don't see the tag or its messages. From the finder, you see only what they chose to send: the message, and their phone and location if they added them.
