Quick Answer: The FitBark GPS is a 16-gram cellular tracker that combines live location with vet-style health monitoring — activity, sleep, and behavior-change alerts — in one device, which FitBark calls “the lightest pet tracker ever built.” The hardware costs $69.95 (frequently discounted to around $35–$40), and a subscription is mandatory: $10/month on FitBark’s shortest plan down to $4/month on a 5-year commitment, per FitBark’s own pricing page. It’s easy to confuse with the older, cheaper FitBark 2, which has no GPS and no subscription — if you want location tracking, you need the GPS model specifically, not the original activity monitor.
FitBark built its name on health data, not location — the original FitBark 2 was one of the first “Fitbit for dogs” devices, tracking steps, calories, and sleep with zero monthly fee. The FitBark GPS is a newer, separate product that keeps that same health-tracking core but adds a cellular chip for live location and escape alerts, at the cost of a required subscription. That combination — real GPS plus real health data, in a tracker lighter than almost every rival — is the FitBark GPS’s whole pitch. Here’s how it actually performs and whether the subscription is worth paying.
FitBark GPS by the numbers
- 16 grams — the lightest pet tracker FitBark has built, per the company’s own product page, light enough for small and toy breeds that struggle with bulkier collars.
- $10/month down to $4/month, depending on plan length, per FitBark’s pricing page — the 2-year plan at $6/month is listed as “most popular,” while the shortest 6-month plan runs $10/month.
- 4.6 out of 5 stars in Hepper’s hands-on review, which praised “very precise” location data and a secure zip-tie mount, though it flagged weak setup documentation in the app.
- An estimated 10 million dogs and cats are lost or stolen every year in the U.S., according to the American Humane Society — the reason a live tracker with escape alerts, not just a step counter, matters for any dog that spends time outdoors.

FitBark GPS — Health Monitoring Built Into a GPS Tracker
FitBark GPS Pet Tracker
- At ~16 g, the lightest cellular GPS tracker FitBark makes — comfortable on small dogs and cats.
- Combines live GPS with activity, sleep, and behavior-change tracking (licking, scratching, restlessness) most GPS-only trackers skip.
- Wi-Fi "Safe Place" geofencing sends an alert the moment your dog leaves a set zone.
- 100% waterproof with interchangeable soft covers.
- Trade-off: requires a subscription for GPS and full health features, and setup documentation is weaker than category leaders like Tractive.

What makes FitBark different: health data first, GPS second
Most trackers in this niche — Tractive, Fi, Whistle — started as GPS devices and bolted on activity tracking later. FitBark did the opposite. Its platform was built around behavior and wellness metrics, and vets have used FitBark data in published research on canine health trends. The GPS model keeps that same health engine — sleep quality, calorie estimates, and alerts when scratching or licking spikes above your dog’s normal baseline — and adds live cellular location on top. If you want a tracker that tells you something is wrong with your dog’s health, not just where it is, this is the one built for that from the ground up.
The subscription: cheaper long-term than it looks
FitBark’s pricing rewards commitment more aggressively than most rivals. The shortest plan (6 months) runs $10/month, but the 2-year plan — FitBark’s own “most popular” tier — drops to $6/month, and a 5-year plan bottoms out at $4/month. That undercuts Tractive’s short-plan pricing and is well below Fi’s $99/year ($8.25/month) baseline, as long as you’re willing to commit for two years or more. The hardware itself lists at $69.95 but is frequently discounted to roughly $35-$40, so most buyers pay closer to the lower figure at checkout.
Where it falls short
Hepper’s hands-on review, while positive overall (4.6/5), flagged app setup documentation as a weak point compared to more polished competitors, and didn’t have head-to-head data against Tractive or Fi to confirm real-world range in weak-signal areas. Because it’s a smaller company than Tractive, expect a narrower retail footprint and less third-party accessory support (cases, clips) than the category leaders.
How FitBark GPS compares to the alternatives
- FitBark GPS vs Tractive: Tractive is the better pure GPS tracker — cheaper short-term plans, a longer track record, and wider retail availability. FitBark GPS wins if health and behavior data matter as much as location to you.
- FitBark GPS vs Fi Series 3: The Fi Series 3 is a rugged, chew-resistant built-in collar with up to 3 months of battery, better suited to a determined escape artist. FitBark GPS is lighter and adds deeper wellness metrics, but its clip-on/tag design isn’t as bite-proof.
- FitBark GPS vs FitBark 2: The FitBark 2 is FitBark’s original, GPS-free activity monitor — smaller, cheaper, and completely subscription-free, but it can’t tell you where your dog is. Choose it only if location tracking isn’t a need; see our best dog activity tracker guide for where it ranks against PitPat and PetPace.
The bottom line
The FitBark GPS earns its spot for one reason: nothing else in this category packs live GPS and genuine vet-style health monitoring into a 16-gram device. If location is your only concern, Tractive is cheaper on short plans and simpler to set up. If your dog is a serious escape artist, the Fi Series 3 and its 3-month battery are the tougher pick. But if you want to know both where your dog is and whether something’s wrong with them health-wise, the FitBark GPS is the only device built for both jobs at once — just don’t confuse it with the cheaper, subscription-free FitBark 2, which only does the health half.
