10 Best Dog Activity Tracker 2025 in the United States

The Fi Series 3 Smart Dog Collar is a strong choice for pet owners looking to keep a close eye on their dog's location and health without frequent recharging. Its standout feature is the always-on GPS tracking that works nationwide without range limits, which is much more reliable than short-range trackers like AirTags. The collar also offers escape alerts that notify you if your dog leaves a safe zone, helping to quickly locate pets who wander off. In terms of health, the collar monitors activity and sleep, presenting insights through an app available on both iOS and Android, making it easy to understand your dog's behavior and wellbeing.

Battery life is impressive, lasting up to three months on a single charge with wireless charging included, meaning less hassle compared to many trackers that need charging every few days. The collar is durable and waterproof, designed to handle rough play and outdoor conditions with a strong stainless steel build and high water resistance ratings. It also comes with a sleek design that fits comfortably and securely on large dogs, though smaller sizes might be needed for small breeds.

Compatibility with the Fi app is solid, offering a user-friendly experience and reliable customer support, including a free one-year membership with purchase. The collar's price and ongoing membership cost might be a consideration for some. Some owners may find the collar bulkier compared to simpler trackers. This product is well suited for active dog owners who want detailed health monitoring combined with dependable nationwide GPS tracking and are willing to invest in a premium product that emphasizes security, battery life, and durability.

The Tractive XL GPS Dog Tracker is a robust option for dog owners with large breeds over 50 lbs. In terms of GPS tracking, it excels with real-time updates every 2-3 seconds, which is significantly faster than many competitors. This feature, along with the ability to set virtual fences and view location history, makes it especially useful for keeping tabs on adventurous dogs.

The health and activity monitoring feature is a great addition, allowing you to track your dog's health and activity through a convenient app available on both iOS and Android.

In terms of battery life, it offers a range of 5-15 days, which can extend up to 30 days with the Power Saving Zones feature activated, giving you flexibility depending on your dog's activity level and your own monitoring needs.

However, it is important to note that a subscription is required to use the GPS tracking features, starting at $5 a month, which covers the costs of the integrated SIM card and data. The tracker is relatively lightweight at 4.1 ounces and designed to be comfortable for larger dogs. The product also comes with a 2-year manufacturer warranty, which adds peace of mind. On the downside, the subscription requirement may be a deterrent for some, and the reliance on LTE cellular coverage means it may not work in more remote areas without such coverage.

The Tractive Smart Dog GPS Tracker is well-suited for dog owners who want detailed, real-time location tracking and health monitoring. Its GPS updates every 2–3 seconds with unlimited range, which is impressive compared to many trackers that update less frequently or have limited coverage. This makes it a strong choice if you need precise, constant tracking, especially for dogs that roam freely. The device also monitors vital signs like heart and respiratory rates, which is a rare feature in dog trackers and useful for spotting health issues early. Additionally, the tracker alerts you to changes in your dog’s activity and barking patterns, helping you catch unusual behavior. It includes escape alerts with customizable virtual fences and location history, adding peace of mind for pet safety.

The tracker is lightweight and waterproof, suitable for dogs over 8 pounds, and offers up to 14 days of battery life, which is quite good for a device with continuous GPS monitoring. On the downside, it requires a monthly subscription starting at $5 for cellular connectivity and data, which adds ongoing costs. While the device is compact and comfortable, some users might find the need for a subscription inconvenient or prefer a tracker that doesn’t require it. The app is an integral part of the experience, providing health and location insights, and generally supports the device’s functionality.

Considering these factors, this tracker is ideal for active dog owners who value detailed health monitoring and continuous GPS tracking, and who are comfortable with the subscription model.
