About This

REAL-TIME GPS TRACKING, NO RANGE LIMITS: See your dog's live location nationwide in the Fi app. This GPS dog tracking collar runs on nationwide cellular and GPS coverage with 2x improved GPS performance over earlier generations, so it keeps up on trails, at the park, on road trips, and anywhere else the day goes.
FI MEMBERSHIP REQUIRED: All Fi trackers require a GPS/LTE Plan that you can select at activation.
ESCAPE ALERTS AND LOST DOG MODE: Draw safe zones around home, the yard, or a sitter's house and get an alert the moment your dog slips out. Lost Dog Mode switches to rapid live location updates so you can follow their path and act fast. The whole household can share the app, so everyone is alerted together.
AI HEALTH AND BEHAVIOR MONITORING: The Fi app counts steps and tracks activity, sleep, and rest, and detects behaviors like barking, licking, scratching, eating, and drinking. Long-term trends make it easy to notice quiet changes in routine that may be worth a vet conversation, and weekly goals with breed comparisons keep daily activity on target.
BUILT FOR REAL DOG LIFE: A stainless steel frame, IP68 waterproof rating, built-in LED light for night visibility, and wireless charging stand up to daily wear. Check live location and activity right from your Apple Watch, and ask the built-in AI Companion care questions, with vet visit and vaccine reminders plus uploaded health records organized in one place.
