Best Dog Wearables for Heart Disease Monitoring in 2026

Compare dog wearables for resting respiratory rate, heart trends, alerts, vet sharing, GPS, and the limits of cardiac monitoring.

Best Dog Wearables for Heart Disease Monitoring in 2026

If your dog has heart disease, the best wearable is not necessarily the one with the most sensors or the strongest activity-tracking features. The more important question is whether it can help you monitor the changes your veterinarian actually cares about—especially resting respiratory rate, resting heart-rate trends, sleep, and activity—without creating false reassurance or unnecessary panic.

A wearable can make home monitoring more consistent and may help you share a longer record with your veterinary team. It cannot replace an examination, echocardiogram, radiographs, ECG, laboratory testing, or prescribed treatment. An abnormal alert is not a diagnosis, and a normal trend does not rule out worsening disease.

For most owners, the decision comes down to five factors:

Does it measure resting respiratory rate automatically?
Does it show trends and personalized changes rather than isolated numbers?
Can you export or share useful data with your veterinarian?
How strong is the independent evidence behind the measurements?
Will the dog wear it reliably, and are the health features dependent on a subscription or cellular connection?

1. Invoxia Biotracker: strongest cardiac-focused feature set

Invoxia says Biotracker measures resting heart rate, resting respiratory rate, heart-rate variability, activity, and sleep. Its Heartprint feature is intended to identify unusual changes in cardiac rate or rhythm, and the company markets early atrial-fibrillation detection. The latter should be understood as a vendor claim rather than independently established diagnosis or a replacement for an ECG. (Invoxia)

Biotracker is particularly interesting for owners who want a personalized baseline. Invoxia says the app can alert owners to unusual cardiac, respiratory, or activity changes relative to that baseline and can generate downloadable PDF health reports for veterinary discussions. (Invoxia)

There is also relevant research behind the platform. A 2025 prospective study analyzed Invoxia data from 703 apparently healthy dogs in their home environments. In that study, measurements were recorded when dogs were lying down and immobile for at least 40 seconds, using collar-based seismocardiography and intermittent sessions rather than uninterrupted full-time measurement. (Frontiers in Veterinary Science)

That distinction matters. “Continuous monitoring” or frequent health tracking does not necessarily mean every heartbeat and breath is measured continuously. The practical value may be in repeated resting snapshots and longer-term trends.

Consider Biotracker if: your priority is the broadest cardiac-oriented feature set, personalized alerts, downloadable reports, and GPS in one collar.

Use caution if: you are looking for confirmed arrhythmia diagnosis, ECG data, or a device that can determine whether medication should be changed without veterinary review.

2. PetPace: broad vital-sign monitoring and veterinary support

PetPace says its smart collar measures pulse, heart-rate variability, respiration, temperature, activity, sleep, calories, posture, and location. Its website also advertises measurements taken every few minutes, AI-based health insights, alerts, and access to licensed veterinary telehealth. (PetPace)

This broad approach may appeal to owners whose dog's cardiac status is affected by more than heart rate alone. Respiratory changes, temperature, activity, sleep disruption, posture, and reduced movement can all provide context for a conversation with a veterinarian. However, context is not the same as diagnosis. A change in breathing or activity can also reflect pain, respiratory disease, anxiety, heat, medication effects, or another non-cardiac problem.

PetPace describes its system as clinically validated, but that phrase should not be treated as proof that every measurement is equally reliable for every breed, body shape, coat type, or stage of heart disease. Ask what studies support the specific metric you care about and whether the tested population resembles your dog.

Consider PetPace if: you want a wider health picture, frequent measurements, and advertised access to veterinary telehealth alongside the collar.

Use caution if: your purchase decision depends on a specific clinical threshold, such as deciding whether congestive heart failure is worsening. Confirm with your veterinary team how PetPace readings should be interpreted and what evidence supports that use.

3. Maven Pet Smart Collar: promising respiratory-rate support

Maven says its system tracks resting respiratory rate and heart-rate trends, along with activity, rest, itch behaviors, and water intake. It sends alerts for unusual changes and states that it does not diagnose or treat disease. (Maven Pet)

The product also has a relevant peer-reviewed evaluation. A 2026 American Journal of Veterinary Research study compared Maven respiratory-rate readings with manually counted rates in 19 healthy dogs across 120 paired measurements. The reported bias was -0.78 breaths per minute, with 95% limits of agreement from -6.81 to 5.26 breaths per minute. The authors concluded that the collar could aid resting respiratory-rate monitoring while emphasizing that clinicians must consider the limits of agreement. (PubMed)

The study is useful, but it should not be overgeneralized. It involved apparently healthy dogs, so its results do not automatically establish performance in dogs with advanced heart disease, congestive heart failure, unusual chest conformation, heavy coats, or difficult sensor fit.

Consider Maven if: resting respiratory rate and health-change alerts are more important to you than a large GPS feature set.

Use caution if: you plan to act on a single reading. Confirm unexpected results manually and discuss sustained changes with your veterinarian.

4. Tractive: a practical health-and-GPS option

Tractive's health documentation lists average resting heart rate and resting respiratory rate, seven-day trend charts, and status indicators such as normal, higher, or lower on supported models. The system also combines health monitoring with GPS, activity, and sleep tracking. (Tractive)

This may be a sensible choice for an owner who already values location tracking and wants basic health trends in the same app. Its seven-day view can be more useful than a single number because it helps show whether a change is persistent or unusual for that individual dog.

Compatibility is important: Tractive says health features are model-dependent, so verify the exact tracker before buying. The company also explicitly states that its products are not medical devices and are not intended to diagnose health conditions. (Tractive)

Consider Tractive if: GPS, activity, sleep, and basic resting vital-sign trends are all priorities.

Use caution if: you need detailed cardiac-rhythm analysis or a report specifically designed for veterinary cardiac review.

Why resting respiratory rate matters

For many dogs with heart disease, resting respiratory rate is one of the most useful home measurements. Virginia Tech recommends measuring it at least daily while the dog is sleeping soundly and says a normal resting rate generally does not exceed 36 breaths per minute. (Virginia Tech, “At Home Respiratory Rate Monitoring”)

The goal is not to compare your dog with every other dog. It is to establish your dog's usual pattern and watch for a sustained increase or a threshold your veterinarian has specifically given you. A wearable can make this easier, but manual checks remain valuable for confirmation.

Virginia Tech's handout identifies Cardalis as a free phone app for manually tracking resting respiratory rate. The recommended method is to count breaths while the dog is sleeping, count for 30 seconds, and multiply by two. (Virginia Tech, “At Home Respiratory Rate Monitoring”)

How to choose and use a wearable safely

Before buying, ask your veterinarian which metrics matter for your dog's diagnosis and what change should prompt a call. Then check:

Measurement conditions: Does the device measure only when the dog is still, or also during sleep? How often are readings taken?
Fit: Can the collar stay in the same position? Could coat length, neck size, chest shape, movement, or poor contact affect readings?
Alerts: Are they based on a personalized baseline, a fixed threshold, or a general status indicator?
Sharing: Can you export a PDF, share a trend chart, or provide a veterinary dashboard?
Connectivity: Does the health function require cellular service, GPS, a nearby phone, or an ongoing plan?
Cross-checking: Can you continue manual sleeping respiratory-rate counts when an alert appears?
Evidence: Were dogs with diagnosed heart disease studied, or only healthy dogs?

A 2025 study of a wireless veterinary harness found that heart-rate and respiratory-rate readings generally followed manual trends, but individual agreement was not strong enough for clinical decisions without confirmation. Fur length and chest conformation affected some measurements. (Animals, MDPI) This is a useful reminder that even a promising trend device should not be treated as a stand-alone clinical instrument.

Bottom line

Invoxia Biotracker is the most cardiac-feature-focused option in this comparison, especially if personalized cardiac alerts and veterinary reports matter. PetPace is appealing for broad vital-sign monitoring and advertised veterinary telehealth. Maven is worth considering when resting respiratory-rate trends are central to your decision. Tractive makes more sense when GPS and everyday tracking are equally important.

Regardless of the device, use it as a monitoring aid alongside veterinary care. Seek prompt veterinary or emergency help for increased breathing effort, collapse, severe lethargy, bluish or pale gums, or other acute symptoms—do not wait for a wearable alert. Establish your dog's baseline with your veterinarian, confirm surprising readings manually, and treat sustained changes as a reason to contact the care team rather than as a diagnosis.
