PawPulse vs Tractive at a glance
Tractive is a GPS tracker first. Tractive sells the DOG 6 for $79 plus a required subscription from $5 to $10 per month depending on term, advertises up to 2 weeks of battery with Power Saving Zones, and lists the DOG 6 at 40 g. It offers resting heart-rate and respiratory-rate trends and states it is not a medical device. Its virtual fences send alerts.
PawPulse Lucero covers the boundary with fence training that uses vibration cues, never shock, and then keeps going: contactless heart rate, heart-rate variability, and breathing monitoring that works on every coat (Kinetic sensing), breath VOC and air-quality context, Prism Insights baselines for 100+ breeds, built-in Pulse Rhythm calming, and PawPulse Care sharing with your vet. Location runs on GPS and LTE with satellite-ready backup where carrier and certification allow, all on a 28g module.

Competitor figures come from official product pages as of September 2026. Where we found no official figure, the cell says so rather than estimating. A dash, cross mark, or "Not advertised" means we did not find that feature advertised on the maker's site as of September 2026. Weights are shown in grams; figures a maker lists in ounces are converted and rounded. Lucero pricing and battery figures are announced at launch; a $5 reservation holds your spot.
Weight on the neck
Lighter is kinder.
Especially for smaller dogs.
Your dog wears it every hour of every day, so every gram counts. The Tractive DOG 6 tracker is listed at 40 g. The Lucero module is 28 g, and it carries the full health stack.
10 lb dog
15 lb dog
30 lb dog
At 28 grams, the PawPulse module is about 0.6 percent of a 10 lb dog's body weight and about 0.2 percent of a 30 lb dog's. The strap adds weight on top. Tractive lists the DOG 6 tracker at 40 g and for dogs above 9 lb (tractive.com). Both figures are device weights; the collar or strap adds weight to each. The 3-5% band is a rule of thumb from wildlife-tracking research, not a veterinary standard. Scale runs 0 to 6 percent.
Worn every hour
A collar isn't a jacket you take off. Lucero is built to stay on day and night, so resting heart rate and breathing are captured while your dog sleeps. Every gram rides along the whole time.
Small airways, gentle gear
Veterinary guidance from VCA Animal Hospitals suggests a harness rather than a collar for dogs with tracheal collapse, a condition the American College of Veterinary Surgeons notes is most common in small breeds.
Pressure on the neck
Small studies have found that pulling against a collar can temporarily raise eye pressure in dogs, while a harness did not.
Manufacturers set their own minimum dog sizes: SpotOn lists 15 lb, Halo lists 10 lb, and Tractive DOG 6 lists 9 lb, per their product pages.
Ask your veterinarian if your dog has airway, eye, or neck conditions.

What Lucero adds
Lucero is for owners who want more than resting trends.
HRV, not only resting heart rate
Tractive offers resting heart-rate and respiratory-rate trends. Lucero adds heart-rate variability to contactless heart rate and breathing monitoring that works on every coat.
Boundary cues on the collar
Tractive virtual fences send alerts. Lucero fence training adds vibration boundary cues near the edge, never shock, along with the alert to your phone.
Breath and air context
Lucero adds breath VOC trends and air-quality context, so a change in the numbers arrives with the setting around it.
Baselines built for your breed
Prism Insights compares each signal with breed-aware baselines for 100+ breeds and with your dog's own history, so you see patterns instead of one-off numbers.
Calm and care built in
Pulse Rhythm, a three-mode calming haptic you can start from the app, and PawPulse Care sharing with your vet come built into Lucero.
Satellite-ready backup
Lucero pairs GPS and LTE with satellite-ready backup designed for places where cell coverage thins out, with availability depending on carrier and certification.
Two days that need more than a resting number
An open gate at dinner time, and a storm while you are at work. Lucero adds the context and the calm.
The gate the landscaper left open
You find the yard empty at 6:40pm. The question is not only where she is, but how she is doing while you close the distance.
A GPS-only collar tells you
- Her last known position, refreshed as often as the plan allows.
- A geofence alert once she has already left the zone.
- A blank spot if she crosses a dead zone on the way.
- No sense of whether she is trotting, hiding, or exhausted.
Lucero tells you
- Live position with satellite-ready backup, designed so a dead zone does not end the trail at her last fix.
- Vibration boundary cues near the edge and an instant alert to your phone. No buried wire, no shock.
- Heart rate and respiration alongside the map, so you know whether she is moving steadily or running hot.
- Pulse Rhythm on arrival, plus air-quality and temperature context for wherever she ended up.
The first big storm of the season
You are still at work, the sky opens up at four, and you have no idea how the afternoon went until you walk in the door.
A GPS-only collar tells you
- A location that says he is home, which you already knew.
- Maybe a spike in activity minutes, logged with no context.
- No sense of when the hard part started or stopped.
- Nothing you can act on until you are back in the room.
Lucero tells you
- A timeline showing when his resting heart rate and breathing rose above his usual evening baseline.
- Audio and motion cues that line up the restlessness with the loudest part of the storm.
- Pulse Rhythm, the collar's gentle haptic pattern, which you can start from the app while you are still away.
- A note in the app afterwards showing how long it took him to settle back toward his own normal.
PawPulse surfaces patterns and context for you and your vet. It is a consumer wellness product, not a medical device.

It is light, but not the lightest. Tractive lists the DOG 6 at 40 g, for dogs above 9 lb. Lucero's sensing module is 28 g, about 30 percent less, with the strap extra. A collar is worn every hour of every day, so every gram counts, most of all on small and toy breeds.
Yes. Setup is dock, pair in the PawPulse app, and fit the collar. Prism Insights starts from breed-aware baselines, so Lucero is useful before it has weeks of your dog's history.
