In this review the Fi Series 3+ Smart Dog Collar in Blue, Extra Small is assessed for owners who need accurate location tracking and daily activity monitoring for small dogs. The bottom line: this collar is best for pet parents seeking reliable GPS location and simple activity insights combined with a waterproof design and an LED safety light. Setup and everyday use are straightforward, and the included six month membership makes initial use convenient, offering peace of mind for those worried about escapes or lost walks.

Key Features

• GPS Tracking: Provides accurate location updates so owners can quickly pinpoint a missing pet and reduce search time.
• Activity & Fitness Monitor: Tracks daily movement and activity levels to help owners monitor exercise and general health trends.
• Waterproof Construction: The collar withstands wet conditions so it continues to work through rain or swimming without special handling.
• LED Light: Built-in LED increases visibility on evening walks and helps locate a pet in low light.
• Escape Alerts: Sends alerts if the dog leaves a designated area, giving quick notice of potential runaways.
• Six Month Membership Included: Nationwide coverage is active from the start, removing the immediate need for a paid plan.

Who It's For

The Fi Series 3+ in Extra Small is ideal for owners of small-breed dogs who want continuous GPS tracking and activity data without bulky hardware. It suits people who value ease of setup and clear location information for daily use and occasional escapes.

It is less appropriate for owners who need multi-dog device management at scale or expect perfectly consistent battery life in every use case; some customers report variable battery performance. Those needing detailed veterinary-level health diagnostics should look at dedicated medical monitors instead.
