10 Best GPS Trackers For Small Dogs 2025 in the United States

The Fi Series 3 Smart Dog Collar is a feature-rich GPS tracker designed to keep tabs on your pet’s location and health. Its small and lightweight design ensures comfort for small dogs, and the durable, waterproof construction (IP68 and IP66K) makes it ideal for active pets. One of its standout features is the impressive battery life, which can last up to three months on a single charge, significantly reducing the frequency of recharges.

The collar provides nationwide coverage with live, always-on GPS tracking, making it suitable for pet owners who need reliable tracking without range limitations. Additionally, the real-time escape alerts are a valuable safety feature, ensuring you are immediately notified if your dog leaves a pre-defined safe area. The collar also offers health and activity monitoring, providing insights through an easy-to-use app available on iOS and Android devices.

The product requires a Fi Membership after the first free year, which may be an ongoing cost to consider. While the collar does not have a display, it seamlessly connects to your smartphone for all interactions. Its 400-lb tug resistance adds to its durability, and the built-in LED light is useful for visibility in low light conditions. The ease of removing the tracking device to swap bands is another practical feature. The Fi Series 3 is a comprehensive solution for pet owners looking for a reliable, durable, and feature-packed GPS tracker for their small dogs.

The Garmin Alpha TT 25 is a rugged GPS tracking and training collar designed to fit both large and small dogs, making it versatile but possibly a bit bulky for very tiny breeds. It weighs just over a pound and has a slim profile, which is decent for small dogs but not the lightest option available. Its standout feature is the impressive tracking range of up to 9 miles with updates as fast as every 2.5 seconds when paired with a compatible Garmin handheld device (sold separately). This makes it excellent for outdoor activities or hunting where long-distance tracking is important.

The battery life is quite strong, lasting up to 68 hours on a standard battery with dynamic tracking, and can be extended to 136 hours with an upgraded battery pack—great for extended use without frequent recharging. It’s built to be waterproof and durable, adding reliability for active dogs in various environments. The collar also offers training features, including 18 levels of stimulation, tone, and vibration, controlled via the handheld device, providing useful behavior management tools in one package. However, the collar itself requires pairing with a separate Garmin handheld unit to access full tracking and training functions, which adds to the overall cost and setup complexity.

There is no indication of subscription fees, suggesting avoidance of ongoing charges common with cellular trackers. The collar is user-friendly in terms of charging and replacing batteries, and the multicolor LED helps identify your dog easily, even in the dark. This product is best suited for owners of active small to large dogs who want a combined GPS tracker and training tool and are comfortable using the Garmin ecosystem. Those looking for a standalone or simpler, lighter, or cheaper GPS option may want to consider alternatives.

The Garmin Alpha 200/TT 15X Bundle is a robust GPS tracker designed primarily for dog training and hunting. One of its standout features is the sunlight-readable 3.5” touchscreen, which enhances usability outdoors. The device is lightweight at 9.9 ounces, making it suitable for small dogs. Additionally, its ability to track up to 20 dogs at a range of up to 9 miles is exceptional, although this may be more than necessary for typical small dog owners. The real-time tracking is highly effective with a 2.5-second update rate, supported by GPS and Galileo systems.

Battery life is decent at up to 20 hours, but it may require frequent recharging for continuous use. The product is durable and includes a waterproof design, which is crucial for outdoor activities. However, the advanced features like TopoActive maps, Hunt Metrics, and 18 levels of correction might be overkill for everyday pet monitoring. The Garmin Alpha is also backward compatible with existing collars, adding value for those who already have Garmin products.

This device seems more tailored to professional trainers or hunting enthusiasts rather than everyday pet owners. For ease of use, the combination of a touchscreen and button interface offers flexibility, but some users might prefer a simpler device. It is a high-end product packed with features that may be more suitable for specific use cases rather than general pet tracking.
