Tractive vs. Biotracker: The Comparison of Dog Trackers

Updated on August 12, 2026

On raw GPS coverage alone, Tractive has the edge (175+ countries vs. 35+ for the Biotracker) — but on health tracking, the Biotracker goes much further, with atrial fibrillation detection and continuous heart and respiratory rate monitoring that Tractive doesn’t match at the same level of precision. The right choice really comes down to your priority: maximum network coverage for travel, or in-depth daily health monitoring. Here’s the full comparison, without glossing over where each brand genuinely comes out ahead.

Tractive and Biotracker: strengths and limitations

#

Both trackers deliver reliable real-time GPS tracking with safety zones, but their respective strengths differ sharply. Tractive leans on very broad network coverage (175+ countries via 2G/LTE). The Biotracker leans on the depth of its health tracking: continuous heart and respiratory rate monitoring, early atrial fibrillation (AFib) detection, a personalized cardiac signature (“Heartprint™”), a sleep score, and detailed activity recognition (walking, running, play, barking, and more).

Dog GPS tracking in 2026: where do things stand?

#

On raw network coverage, Tractive has a genuine advantage. Its cellular network spans 175+ countries via 2G/LTE, compared to 35+ countries for the Biotracker on 4G LTE-M — a real gap, especially if you travel internationally with your dog a lot. To be clear on this one point: Tractive does it better. Invoxia’s LTE-M network operator keeps expanding coverage, though, so that 35+ country figure is likely to grow over time.

That said, within covered countries the Biotracker has the edge on responsiveness: in Live Tracking mode, it refreshes your dog’s position every second, compared to every 2-3 seconds for Tractive. The gap is modest in absolute terms, but it can matter in situations where every second counts — a dog that’s just slipped its leash in a busy area, for example. The real question isn’t “which one locates better in the abstract” — it’s whether the Biotracker’s coverage fits your actual use case, and what each tracker does beyond location.

Which countries does the Biotracker work in?

#

The 35+ country limit only applies to the Max GPS plan, which relies on the cellular LTE-M network for real-time location. That network currently covers 35+ countries, mainly across Europe and North America, and is still expanding — it’s worth checking the current country list on the Biotracker product page before traveling abroad, especially outside Europe.

The Basic and Plus plans, on the other hand, work anywhere in the world, including outside the 35+ LTE-M countries: they run entirely on Bluetooth (no cellular network involved), so there’s no geographic restriction — in exchange, they don’t include real-time GPS location, only a position reading when your phone is nearby. If health tracking (heart rate, breathing, sleep, activity) is your priority and you’re outside the GPS-covered countries, the Biotracker is still usable; if real-time GPS location matters most and you travel frequently outside the LTE-M footprint, Tractive (175+ countries) remains the more reliable option for never losing signal.

Health tracking: a far more advanced approach with Biotracker

#

This is where the two trackers really diverge. Tractive recently launched its own resting heart rate feature — but in its own launch announcement, the company states outright: “Tractive is not a medical device. While Tractive monitors trends and patterns in your pet’s well-being, it is not intended to diagnose health conditions.” Its heart feature simply compares your dog’s data against “thousands of similar dogs” — a trend indicator, not a screening tool.

The Biotracker takes a different approach: its heart and respiratory rate algorithms are built to flag clinically relevant signals, starting with early detection of atrial fibrillation (AFib), a common canine arrhythmia. That’s the exact kind of detection that caught Cracotte’s dog Emilie’s pulmonary edema in time — read her full story here.

The Biotracker also includes a sleep score (duration, restlessness, interruptions) and automatically generated daily and weekly reports, to track a dog’s wellbeing over time rather than in a single snapshot.

This precision isn’t just a marketing claim — it’s backed by a published scientific validation. The AI-COLLAR study, an international, peer-reviewed study published in Frontiers in Veterinary Science, followed 703 dogs across 29 countries between 2022 and 2025 using the Invoxia Biotracker, with a measured accuracy of 99.6% for heart rate and 98.6% for respiratory rate compared to a portable ECG and manual counting. The Biotracker is also already used in clinical practice — for example at FördeVet in Germany — where at-home monitoring complements regular vet visits, a level of validated use Tractive doesn’t claim.

Biotrack: when your dog’s data reaches the vet directly

#

Where Tractive stops at the owner, the Biotracker extends into the vet’s office. Invoxia built Biotrack, a dedicated platform that lets your veterinarian continuously follow your dog’s biometric data (heart rate, respiratory rate, activity, sleep) from their own dashboard, once they’re invited and connected to your tracker.

Biotrack automatically sorts alerts using AI, prioritizing them by importance and how far they deviate from the dog’s baseline reference values — rather than making the vet sift through raw charts, the platform surfaces the signals that actually deserve attention. Tractive has no equivalent: vet data sharing there is limited to a manual export by the owner, with no dedicated dashboard and no automatic signal sorting.

For a dog at higher risk (a breed prone to heart conditions, a senior dog, or a dog being monitored after a diagnosis), this direct connection to the vet changes what monitoring actually means: instead of data the owner checks occasionally on their own, it becomes shared oversight with a healthcare professional, capable of stepping in earlier when something looks off.

Tractive or Biotracker: which one should you choose?

#

It depends on what you actually need from the tracker.

• Choose Tractive if your priority is pure location tracking across very broad international coverage (175+ countries) — for example if you travel abroad frequently with your dog — mainly for safety and escape prevention.
• Choose the Biotracker if 35+ country coverage fits your needs (notably in Europe and the US) and you want real health monitoring over time on top of location — especially for a breed prone to heart conditions (Cavalier King Charles Spaniel, Doberman, Boxer, and others), a senior dog, or simply to catch a health signal before it becomes visible.

FAQ

#

Does the Biotracker also track location like Tractive?

#

Yes, the Biotracker provides real-time GPS tracking with safety zones, just like Tractive — plus a full health-tracking suite (heart, breathing, sleep, activity).

Can Tractive detect a heart problem in dogs?

#

Tractive offers a resting heart rate feature, but the company states outright that it’s not a medical device and isn’t designed to diagnose health conditions. The Biotracker, with its early atrial fibrillation detection, goes further on this front.

How does the Biotracker’s battery life compare to Tractive’s?

#

The Biotracker lasts up to 15 days depending on usage. Tractive DOG lasts up to 2 weeks in power-saving mode, but noticeably less (a few days) under intensive, continuous tracking.

Is the Biotracker more expensive than Tractive?

#

The Biotracker offers a free Bluetooth-only plan, with paid GPS plans on top going up to roughly $10.83-equivalent/month. Tractive requires a mandatory subscription from around $5/month depending on the commitment length. Check current pricing before comparing — both brands adjust their rates regularly.

Does the Biotracker work without a subscription?

#

Yes: the Biotracker’s Basic plan is free with no commitment ($0/month), and already includes heart/respiratory rate tracking, activity, and sleep via Bluetooth. That’s an important difference from Tractive, which requires a paid subscription to function at all, regardless of use case.

Can my dog’s vet be alerted directly to changes in the data?

#

With the Biotracker, yes: through the Biotrack platform, your veterinarian can be connected directly to your dog’s biometric data and receive AI-sorted alerts based on deviation from baseline values. Tractive has no equivalent — only a manual data export by the owner is possible.

How does Live Tracking refresh speed compare between Tractive and the Biotracker?

#

The Biotracker refreshes location every second in Live Tracking mode, compared to every 2-3 seconds for Tractive. The difference is small in practice, but can matter most in situations where responsiveness counts, like searching for a dog that has just gotten loose.
