Fi Series 3+ is the smart dog collar that keeps you connected to your dog around the clock. Live GPS tracking shows exactly where your dog is, with nationwide coverage and no range limit, and Escape Alerts with custom virtual fences tell you the instant they leave a safe zone. If they do get out, Lost Dog Mode switches to rapid location updates so you can follow their path in real time. Beyond location, Fi is a complete health and activity monitor for dogs. It counts steps, tracks activity and sleep, and uses AI to detect behaviors like barking, licking, scratching, eating, and drinking. Weekly goals and breed comparisons make it easy to keep your dog moving, and long-term trends make quiet changes in routine easy to notice and worth bringing to your vet. The collar itself is built for real dog life: a stainless steel frame, IP68 waterproofing, a built-in LED light for dark walks, and wireless charging. The Fi app works on iOS and Android, integrates with Apple Watch, and lets the whole household share access, and the built-in AI Companion answers care questions and keeps vet visit and vaccine reminders on schedule. Your purchase includes a 6-month Fi Membership, the GPS and cellular service plan that powers the collar, so GPS tracking, health and behavior monitoring, escape alerts, and the full app experience work from day one with nothing extra at checkout. Membership renews after the included 6 months to keep GPS service active.
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.
6-MONTH MEMBERSHIP INCLUDED, NOTHING EXTRA AT CHECKOUT: One price covers the collar and 6 months of Fi Membership, the GPS and cellular service plan that powers it. No activation fee, no added hardware, no separate signup. Unbox, pair with the Fi app, and tracking, escape alerts, and health monitoring work the same day. Membership renews after the included 6 months to keep GPS service active.
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.
