Losing a dog is one of the most stressful experiences for an owner. GPS trackers can help you find a dog that escapes. Fi and Tractive are two of the most popular. This comparison looks at how they work, their differences and what to consider.
The Short Answer: Fi and Tractive both offer GPS tracking with phone apps and subscriptions. Fi is a smart collar known for long battery life, while Tractive is a clip-on tracker that works with your dog’s existing collar. Both depend on cellular coverage and subscriptions. Neither replaces a microchip and ID tag.
Key Details
| Feature | Details |
|---|---|
| Fi | Smart collar with built-in tracker (check current model) |
| Tractive | Clip-on tracker for existing collars (check current model) |
| Subscription | Both require a subscription |
| Coverage | Depends on cellular networks |
| Extras | Activity tracking and alerts |
What It Is and How It Works
GPS trackers use satellites to find location and cellular networks to send it to your phone. Both Fi and Tractive offer live tracking, escape alerts and activity tracking.
Fi is built into a collar. It’s known for long battery life between charges, and it uses a home base or your phone to know when your dog is safely at home. Tractive is a small device that clips onto your dog’s existing collar or harness. Its battery generally needs charging more often, especially with frequent live tracking. Both brands have released newer models over time, so check current specs before buying.
Both rely on cellular networks to send location data. In areas with weak or no coverage, such as remote trails, updates may be delayed or unavailable. Location accuracy also varies with buildings, tree cover and weather.
Trackers don’t replace microchips and ID tags. A tracker can fall off, run out of battery or lose signal. A microchip registered with current contact details and a collar tag with your phone number remain essential. See a guide to choosing the right dog collar.

Do GPS dog trackers need a subscription?
Yes. Both Fi and Tractive require a subscription to send location data over cellular networks.
How long does the battery last?
It varies by model and use. Fi is known for longer battery life. Live tracking drains any tracker’s battery faster.

How accurate are GPS dog trackers?
Accuracy varies with signal, buildings and tree cover. They’re usually accurate enough to locate a lost dog, but not always to the exact spot.
