Tiny tracker, big tech
Peace of mind, clipped right on
The Fi Mini does the heavy lifting so a slipped leash or an open gate never turns into a lost dog — and tells you how they're doing the rest of the time.
Find them fast
Live GPS location anywhere in the U.S. — even off the grid — right in the Fi app the moment they go missing.
Escape alerts
Set safe zones at home, work, or the park and get pinged the instant your dog leaves one.
Health & habits
Tracks steps and activity, flags health trend shifts, and keeps AI-organized vet records — all powered by Fi Intelligence.
Adding one is easy
Clips onto the collar you already love
No second collar, no separate order from Fi. The Fi Mini attaches right to your LUCKY+DOG snap collar — just add it to your order and we'll include it in the same shipment.
The membership is automatically billed $99 semi-annually plus a one-time $20 activation fee ($119) — the same Fi membership that powers the Fi Series 3+. Manage your plan anytime in the Fi app.
How the add-on works
- Pick your snap collar, then check the "Add a Fi Mini" option before checkout.
- Your collar and Fi Mini ship together — one order, one package.
- Activate the Fi Mini in the Fi app and choose your membership plan to turn on GPS tracking.
- The Fi Mini clips to the collar with the included strap, so you can move it between collars anytime.
