Quick Answer: The PetPace Collar v3 is a $299 (list $399) vet-grade health-monitoring collar that reads pulse, HRV, temperature, respiration, and posture every 2 minutes, per petpace.com, and layers a location feature on top — but it’s built as a clinical monitoring tool first and a GPS tracker second. A required subscription runs $13.90–$25/month depending on term length. It’s a strong pick for a senior pet or one managing a chronic condition; it’s expensive overkill if a missing pet, not a sick one, is what you’re actually worried about.
PetPace already shows up across several of our other guides — our best dog activity tracker roundup, best smart cat collar guide, and GPS tracker for multiple dogs comparison all rank it — but it’s never had its own dedicated review. That’s worth fixing, because PetPace is a genuinely different product category from the Tractive/Fi/Halo trackers this site covers most: it’s a clinical wearable that happens to include location, not a location tracker that happens to log some activity data.
PetPace by the numbers
- $299 (list $399) is the current Collar v3 hardware price on petpace.com, plus a required subscription — noticeably more upfront than a Tractive (
$50) or Fi ($149) tracker, because the price reflects the sensor package, not just a GPS chip. - Every 2 minutes is how often the collar samples pulse, respiration, temperature/fever, HRV (stress), posture, and activity, per PetPace’s own spec sheet — a far denser data stream than a step-counting activity tracker.
- Up to 3 weeks of battery life on a single charge, per PetPace — longer than any cellular GPS tracker on this site, because it isn’t holding a constant live-location connection the way Tractive or Fi does.
- IP66 and IP68 rated, per PetPace, meaning it’s built to be dust-proof and water-resistant for daily wear, not just splash-resistant.
- A peer-reviewed study in Frontiers in Pain Research used PetPace’s HRV data to distinguish dogs with osteoarthritis-related pain from healthy dogs — real clinical validation behind the marketing claim, and the reason vets, not just pet owners, have taken an interest in the device.
PetPace Collar v3 vs a dedicated GPS tracker
| Collar | Primary job | Location tracking | Battery | Cost (device + plan) |
|---|---|---|---|---|
| PetPace Collar v3 | Vital-signs health monitoring | Periodic / Find My Pet, not continuous | ~3 weeks | $299 + $13.90–$25/mo |
| Tractive GPS DOG | Live location tracking | Continuous, geofencing | ~1–2 weeks | ~$50 + from ~$5/mo |
| Fi Series 3 | Live location + fitness | Continuous, geofencing | ~2–3 months (base charging) | ~$149 + from ~$9/mo |
PetPace Collar v3 — Best for Chronic-Condition & Senior-Pet Monitoring
PetPace Collar v3
- Continuously reads pulse, respiration, temperature, HRV, posture, and activity — sampled every 2 minutes, per PetPace.
- AI flags deviations from your specific pet's own baseline rather than a population average, and a vet can log into the same portal remotely.
- Up to 3 weeks of battery per charge, IP66/IP68 rated for daily wear.
- GPS is included but built as a supplementary "where's my pet" check, not a continuously updating live map or geofence system.

What the data actually catches
The PetPace pitch is early detection, not fitness tracking — and there’s real research behind it. Beyond the osteoarthritis-HRV study cited above, PetPace’s own clinical-publications page lists multiple peer-reviewed papers using the collar’s sensor data, and the company markets it directly to veterinarians (it’s covered by trade outlets like dvm360) rather than just consumers. In practice that means the collar is tuned to catch slow-building trends — a resting pulse creeping up over days, a temperature that won’t settle, restless sleep — that are easy for an owner to miss but show up clearly once you’re looking at a baseline. For a dog or cat with congestive heart failure, arrhythmia, or a chronic pain condition, that lead time can mean a scheduled vet visit instead of an emergency one.
Why “GPS included” doesn’t make this a tracker
It’s easy to see “Positioning: GPS” on the spec sheet and assume PetPace competes directly with Tractive or Fi. It doesn’t, in practice. Independent hands-on reviews describe the location feature as a periodic map and a “Find My Pet” mode for when a pet actually goes missing — useful, but not the always-on, continuously refreshing live tracking that a dedicated GPS collar provides, and PetPace doesn’t market geofence alerts the way Tractive, Fi, Halo, and SpotOn all do. If keeping tabs on an escape-prone dog is your actual priority, our best GPS dog tracker guide covers the trackers built specifically for that job; PetPace’s location feature is a bonus layered on a health tool, not a replacement for one.
The bottom line
The PetPace Collar v3 earns its price for the right buyer: a senior pet, one managing a diagnosed chronic condition, or a recovery period where a vet wants continuous vital-signs data rather than an owner’s best guess. At $299 plus a $13.90–$25/month subscription, it’s the most expensive collar this site covers, and that’s fine when the clinical depth is the point. It’s the wrong buy if a pet running off is your real worry — for that, the Tractive GPS DOG or Fi Series 3 cost less and track continuously, which is what location-first tracking actually requires.
