Our review of the Fi Series 3+ Smart Dog Collar (Small, Pink) finds it best suited to owners who want confident, always-on location and health monitoring without fuss. The single biggest reason to buy is the markedly improved real-time location tracking: with 2x improved GPS performance and upgraded antennae, this collar keeps pace with adventurous dogs and provides instant escape alerts via Lost Dog Mode. It also combines activity and health insights with robust hardware - IP68 waterproofing, up to 3 months battery life, and a durable design built for active dogs.

Key Features

• Next-gen GPS: 2x improved GPS performance delivers faster, more reliable nationwide tracking so owners can locate their dog in real time with no range limits.
• Health and activity monitoring: AI-powered tracking records activity, rest, barking, scratching, and eating to give meaningful wellbeing insights over time.
• Lost Dog Mode and escape alerts: Instant alerts notify owners the moment a dog escapes, helping speed up recoveries when time matters most.
• Durable, adventure-ready build: IP68 waterproofing and 400 lb tug resistance make the collar suitable for wet weather and strong, active dogs.
• Long battery life and integrations: Up to 3 months of battery life reduces charging hassle and integrates with Apple Watch for on-the-go updates.
• Secure records and membership: The collar stores vet records in one place and includes a free 6 month Fi Membership for full access to GPS and health features.

Who It's For

The Fi Series 3+ Small in Pink is aimed at owners of small dogs who want best-in-class GPS tracking and health insights without buying separate devices. It suits active pets that go off-leash on hikes or in unfenced areas where reliable nationwide location and escape alerts are reassuring.

Owners who need a basic, no-frills collar or those unwilling to maintain a subscription beyond the free period should look elsewhere, because ongoing membership unlocks the full tracking and monitoring experience. Also consider alternate sizes or colors for medium and large dogs.
