10 Best Dog Activity Tracker 2025 in the United States

The Fi Series 3 Smart Dog Collar offers several impressive features for dog owners seeking a comprehensive tracking and monitoring solution. Its standout feature is the live, always-on GPS tracking, which provides nationwide coverage without a maximum range, ensuring you can locate your pet anywhere. The escape alerts feature adds an extra layer of security, notifying you if your dog leaves a designated area, which can be a lifesaver in cases of wandering or escape. The collar also tracks activity and health insights, making it easy to monitor your dog's well-being through the app available on both iOS and Android devices.

Durability is a strong suit, with its stainless steel build, 400-lb tug resistance, and high waterproof ratings. Comfort-wise, the collar is designed to be sleek and user-friendly, and it comes in a small size suitable for most dogs. The battery life is exceptional, lasting up to 3 months on a single charge, which reduces the hassle of frequent recharging. The inclusion of a 1-year membership with the purchase adds value, as it covers the Fi Membership services and customer support.

However, the collar might be on the heavier side, weighing 12.3 ounces, which could be a consideration for very small or lightweight dogs. The initial price point might also be a bit high for some buyers, especially considering the need for ongoing membership after the first year. The Fi Series 3 Smart Dog Collar is a robust choice for pet owners looking for reliable tracking, health monitoring, and durability in a dog activity tracker.

The Fi Series 3 Smart Dog Collar is a highly advanced dog-activity tracker that combines GPS tracking, activity monitoring, and health insights into one sleek device. One of its standout features is the impressive battery life, boasting up to three months on a single charge, which is a significant advantage for busy pet owners. The collar's GPS tracking is precise and works nationwide without a range limit, ensuring you can always locate your dog, especially with the added benefit of escape alerts that activate if your dog leaves a designated area. This is a crucial feature for keeping your pet safe.

Additionally, the collar provides valuable health and activity data, including sleep patterns and behavior insights, all accessible through an app compatible with both iOS and Android devices. Durability is another strong point, with a robust design that includes 400-lb tug resistance and waterproof ratings of IP68 and IP66K, making it suitable for active and outdoor dogs. The inclusion of a 6-month Fi membership adds value, offering customer support and access to all the collar's features.

However, there are a few drawbacks to consider. While the collar size is large and suitable for adult dogs, it might not be the best fit for smaller breeds or puppies. Lastly, the collar's display is analog, which might not appeal to those looking for a more modern digital display. Despite these minor issues, the Fi Series 3 Smart Dog Collar is a robust choice for pet owners seeking comprehensive tracking and monitoring for their dogs.

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. This can help keep your pet in optimal shape by tracking their daily activity and sleep patterns. The tracker is also durable and waterproof, making it suitable for active dogs. 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.
