10 Best Pet Trackers 2025 in the United States

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.

The Garmin Alpha 200/TT 15X Bundle stands out in the pet-tracker category, especially for dog owners with specific needs such as training or hunting. Its GPS accuracy is enhanced by using multiple satellite systems, allowing for reliable tracking of up to 20 dogs from a distance of up to 9 miles, making it suitable for large properties or professional use. The device is equipped with a 3.5-inch sunlight-readable touchscreen, and a button-operated interface tailored for quick adjustments, which is beneficial in dynamic environments.

In terms of battery life, the user-replaceable battery offers up to 20 hours of operation, which is decent for day-long activities but may require frequent charging for extended use. The bundle includes features like preloaded maps, satellite imagery, and a built-in compass, which are great for hunters or outdoor enthusiasts. Additionally, the Hunt Metrics feature provides insights into each dog's behavior, helping maintain their health and safety.

The device's size and weight (9.9 ounces) might be a bit cumbersome for smaller dogs. The range of 9 miles is impressive but might not be necessary for casual pet owners or those with smaller yards. Also, while the system is backward compatible, it may require additional purchases for full utilization with multiple dogs. There are no subscription fees mentioned, which could be an advantage over competitors that require ongoing costs. The Garmin Alpha 200/TT 15X Bundle is a robust choice for serious dog owners who need advanced tracking and training capabilities, though it might be more than what average pet owners need.
