10 Best Pet Trackers 2025 in the United States

The Garmin Alpha 300i is a powerful handheld GPS tracker and training system designed especially for tracking dogs, making it ideal for hunters or active dog owners who manage multiple dogs at once. It offers highly accurate GPS tracking with updates every 2.5 seconds and a solid range of up to 9 miles, allowing you to monitor your dogs' locations in real time. The 3.5-inch touchscreen is responsive and easy to use, even with gloves on, which is handy outdoors.

One strong point is the long battery life—up to 55 hours on a single charge—so you can rely on it for extended trips without frequent recharging. The system supports tracking for up to 20 dogs and includes features like real-time alerts for activities such as when a dog is “treed” or “on point,” which can be very useful for hunters. The included dog collar is lightweight, rugged, waterproof, and equipped with LED lights for visibility in low light. It uses a combination of GPS and radio frequencies to maintain a clear signal and avoid interference, enhancing reliable tracking.

The device is somewhat bulky at 3.4 pounds for a handheld tracker, which might feel heavy compared to simpler pet trackers. If you need advanced tracking and training combined with safety features and can handle a larger, professional-grade device, this Garmin system is an excellent choice. Casual pet owners looking for a simple tracker might find it more complex and sizable than necessary.

The Fi New Series 3+ Smart Dog Tracker Collar is designed to keep a close eye on your dog’s location and health with its GPS tracking and behavior monitoring features. It offers accurate GPS tracking enhanced by AI, which helps ensure you know exactly where your dog is, and it includes escape alerts and a virtual fence to notify you if your pet leaves a designated safe area. The collar is lightweight at just 47 grams (or 1.66 ounces), making it comfortable for larger dogs. It’s also waterproof, so it can handle outdoor adventures and wet conditions without damage. Battery life is generally strong thanks to its lithium-ion battery, and the product includes a 12-month membership for the tracking service, though continued use will require subscription fees after this period. The device connects with Apple Watch, adding convenience for iPhone users.

The collar is sized for extra-large dogs, so it might not fit smaller pets well. Some users might find the subscription fees a bit of an ongoing cost to consider. The warranty lasts 6 months, which is somewhat short. With a solid customer rating around 4.2 out of 5, it is reliable for pet owners looking for a durable, accurate tracker with health monitoring and smart alerts, especially if you have a larger dog and want integration with Apple devices.

The Garmin Alpha TT 25 is a strong choice for dog owners looking for a reliable GPS tracking and training collar, especially for large and small breeds. Its standout feature is the impressive tracking range of up to 9 miles with updates every 2.5 seconds (when paired with a compatible Garmin handheld device), which means you can keep a close eye on your dog even at a good distance. The collar is built tough and waterproof, making it suitable for outdoor use in various weather conditions. Despite its rugged design, it remains relatively slim and lightweight at just 1.3 ounces, so it won't feel bulky on your dog.

Battery life is quite flexible — with dynamic tracking that adjusts based on your dog’s movement, you can expect up to 68 hours on a standard battery pack or up to 136 hours with an upgraded pack. Plus, batteries are user-replaceable, so you won’t have to worry about downtime. The collar also offers 18 levels of training stimulation plus tone and vibration, giving you multiple ways to communicate with your dog remotely using a Garmin handheld. Activity monitoring is basic but supported through the tracking features.

It is important to note that the collar requires pairing with Garmin’s handheld devices, which are sold separately and may add to the overall cost. Additionally, some features may require subscription fees, so it’s worth checking those details before buying. If you want a durable, high-performance tracking and training collar with long battery life and advanced control options, the Garmin Alpha TT 25 fits well, especially for active dog owners who need reliable GPS tracking over several miles.
