10 Best GPS Trackers For Small Dogs 2026 in the United States

The Fi New Series 3+ Smart Dog Tracker Collar is designed to keep small dogs safe with highly accurate GPS tracking that works nationwide without range limits. It stands out for providing real-time location updates every few seconds, along with custom escape alerts that notify you the moment your dog leaves a designated safe area. This tracker also offers advanced health and behavior monitoring, tracking activities like barking, scratching, and even eating, all visible through the easy-to-use Fi app.

It integrates well with Apple Watch, iPhones, and Android devices, letting you check your dog’s status quickly and get reminders for vet visits or vaccinations.

However, the collar weighs 77 grams, which might feel a bit heavy for very small dogs.

Another consideration is the included 12-month membership; continued use requires a subscription, which adds to the ongoing cost.
