10 Best Dog Trackers 2025 in the United States

The Fi Series 3 Smart Dog Collar is an advanced accessory for dog owners who want to keep track of their pets. It uses precision GPS tracking with nationwide coverage, allowing you to always know your dog's location. One of its standout features is the Escape Alerts, which notify you if your dog leaves a designated area, helping you act quickly to bring them back safely.

This collar provides health and activity insights, displaying your dog's movements and sleep patterns through an app available on iOS and Android. The battery life is impressive, lasting up to three months on a single charge, and it comes with a wireless charging base. Durability is another strong point, with the collar featuring a sleek, stainless steel design that can withstand up to 400 pounds of tug resistance and is waterproof rated at IP68 and IP66K. The collar is easy to remove and swap bands, giving owners flexibility.

One drawback is the lack of a display, which means all information must be accessed via a smartphone. Additionally, after the included one-year membership, there will be subscription fees to continue using some of the features. At 13.76 ounces, this collar is on the heavier side, which might not be suitable for smaller dogs. This product is best for dog owners who prioritize safety and health tracking and are comfortable using smartphone apps.
