What a dog respiratory rate monitor actually measures, and why most collars can't tell you

The dog is asleep on the couch. His pet parent counts chest rises. Seventeen. Eighteen. They lose count, start again. They do this every night because the cardiologist said to, because the dog has mitral valve disease, because a resting respiratory rate above 30 breaths per minute means a call to the clinic in the morning. They have been doing it by hand for six months.

There are devices on the market right now being sold as dog respiratory rate monitors. Most of them cannot do what that owner is doing on the couch. They count steps. They classify states as "active" or "resting." They do not detect breathing.

This matters if you are building a product in the dog health monitoring space. The distinction between a device that actually measures respiratory rate and one that merely implies it is the difference between a clinical tool and a sophisticated activity tracker with better marketing.

Why respiratory rate is not a secondary metric

Veterinary cardiologists treat resting respiratory rate as one of the most specific early indicators of developing heart failure in dogs. Most dogs have a normal resting respiratory rate of between the mid-teens and mid-20s breaths per minute. A resting respiratory rate over 35 to 40 breaths per minute is considered abnormal. For any individual pet, an increase of more than 20% above their average resting rate is considered a flag worth investigating.

That threshold has clinical weight. In dogs with heart disease, an increased resting respiratory rate is an early sign that heart failure may be developing. Catching the increase early can limit how sick the dog becomes, reduce the likelihood of hospitalization, and reduce the costs associated with heart failure treatment. The Cardiac Education Group, which publishes monitoring protocols for dogs with cardiac conditions, recommends that owners track breathing rate once or twice weekly for dogs with significant heart disease and daily for those already on diuretics like furosemide.

The owners who follow that protocol are not doing it casually. They are watching their dogs sleep, counting for a full minute, logging the number. They are the buyers your product needs to reach. And right now, most of what they are being sold does not actually help them.

The problem with the current market

Search "dog respiratory rate monitor" and you will find two categories of product that look almost identical from the outside.

The first is a true physiological monitor: a wearable device with a sensor capable of detecting the mechanical or electrical signals the body produces with each breath. The second is a movement tracker with a "health" label on the packaging, a step counter with sleep classification added on top.

The gap between these two products is not visible to a buyer browsing a retail page. Both come as collar attachments. Both connect to apps. Both produce health reports. The confusion is nearly universal, and it is costing brands that have invested in real sensor technology, because they are losing shelf space to products that cannot match their clinical output.

The same confusion runs through GPS and containment devices. Owners comparing a Tractive or Fi tracker against a health-focused device are not always comparing like for like. GPS trackers answer one question well: where is my dog? They use location data, not physiological signals. They do not monitor breathing rate. The distinction is almost never stated clearly in product descriptions, which means buyers who think they are purchasing a respiratory monitor often end up with a location device that reports activity levels.

Brands that can clearly explain what their sensor actually detects, and how that differs from a step counter or a GPS tag, own the conversation.

What it takes to actually measure respiratory rate

Breathing produces two things a sensor can detect: chest wall movement and the mechanical forces each breath generates through the body. Different device architectures target one or both.

The most common approach in consumer pet wearables is ballistocardiography, known as BCG. A BCG sensor detects micro-movements produced by heartbeats and breathing when pressed against the animal's body. Because cardiac contractions and respiratory cycles each generate distinct mechanical signatures, a BCG device can separate the two signals and produce independent readings for heart rate and respiratory rate, without shaving the animal, attaching electrodes, or requiring the animal to be sedated.

A 2025 peer-reviewed study published in Veterinary Sciences by researchers at Jeju National University tested a BCG-based wearable on both healthy and anesthetized dogs, comparing results against traditional electrocardiography. Under normal conditions, the BCG wearable provided reliable data and was efficient at detecting heart and breathing rates. BCG proved useful because of its rapidity and non-invasive nature, making it a helpful tool for veterinary use.

That validation is meaningful for brands because it is the clinical foundation a product can be sold on. A device that produces respiratory rate data validated against ECG is not the same product as one that estimates breathing from movement. The sensor architecture is different. The signal quality is different. The clinical conversation the device enables is different.

A separate long-term international observational study, the AI-COLLAR study published via the National Institutes of Health and involving 703 apparently healthy dogs monitored over a median of 189 days, reported accuracy rates of 99.6% for heart rate and 98.6% for respiratory rate, regardless of the dog's breed, age, body weight, or coat characteristics, compared against portable ECG for heart rate and manual counting from thoracic video recordings for respiratory rate. The study also found that both heart rate and respiratory rate decreased in early life, stabilized, then increased slightly in older dogs — the kind of longitudinal trend data that only continuous monitoring over time can produce.

What buyers actually need from a dog respiratory rate monitor

The owner counting breaths on the couch does not want a trend over six months. They want to know if tonight's number is 28 or 34.

That is the immediate use case. But the durable value of a respiratory rate monitor is not the single reading. It is the baseline. A device that has been on a dog for three weeks knows what that dog's normal resting rate looks like at 2am on a Tuesday. It knows whether last night's reading of 29 is in range or represents a 15% climb from that dog's personal average. Manual counting, done twice a week, cannot build that baseline with the same resolution. Continuous automated monitoring can.

A dog who slept all afternoon because it was 95 degrees outside looks the same in an activity log as a dog who slept all afternoon because something was wrong. Devices that measure physiological markers, including pulse and respiration, give you a different layer of information.

For senior dogs, dogs on cardiac medications, brachycephalic breeds with structural respiratory vulnerabilities, and post-surgical recoveries, that layer is what the owner is paying for. Not the GPS function. Not the step count. The breathing number.

The brand that understands this is positioned to own the senior dog segment, the cardiac management segment, and every owner whose vet has said "keep an eye on the breathing."

The PuresPet PHH-23: one device for respiratory monitoring and GPS tracking

The PuresPet PHH-23 is a sourcing option for pet brands that want to bring both capabilities to market without managing two separate hardware SKUs.

The device monitors heart rate, respiratory rate, body movement, and BCG waveform continuously, around the clock. It generates HRV reports, sleep analysis, and health summaries, and flags abnormal readings for review via its companion app. All of this runs through a BCG sensor architecture, not an accelerometer-only design. The device is CE and FCC certified.

Layered on top of the health monitoring is 4G Cat.1 cellular connectivity with full GPS and Wi-Fi positioning, trajectory tracking, and electronic fence alerts. The same collar attachment that a cardiologist might recommend for ongoing respiratory rate tracking is also a GPS device that sends an escape alert if the dog leaves the yard.

At 125 x 34 x 14mm and 55 grams, the PHH-23 is best suited to medium and large breeds. Battery capacity is 750mAh, with an IP66 weather resistance rating. Working temperature range is -20 to 45 degrees Celsius, which covers cold-climate markets where the combination of outdoor activity and senior dog health concerns makes a dual-function device commercially relevant.

From a sourcing standpoint: minimum order quantity is 100 units per color per size, with a production lead time of 20 to 25 days and a sampling lead time of 7 to 10 days. OEM and ODM arrangements are available, including logo, packaging, and companion app customization.

For brands that have been selling a GPS tracker and are now fielding customer questions about health monitoring, the PHH-23 is a product that answers both questions at once. For brands entering the health monitoring category for the first time, it allows a single launch that covers the respiratory monitoring use case without abandoning the GPS feature that remains a core retail driver.

More information on the PHH-23 is available at purespet.com.

The conversation your product needs to have

When a dog owner types "dog respiratory rate monitor" into a search engine, they are usually in one of two situations. The first is reactive: the vet told them to track breathing at home and they are looking for something better than counting by hand. The second is anticipatory: they have a senior dog, a breed with known cardiac risks, or a dog who has started sleeping differently, and they want to be ahead of it.

Both situations involve a buyer who has already decided they want more information than they currently have. The product that wins their purchase is not the one with the most features. It is the one that answers the specific question they are asking, in language they trust.

"Monitors your dog's respiratory rate" means something to them. "Tracks activity and rest" does not.

If your product description does not use the first phrase, backed by sensor architecture that supports it, you are leaving that buyer to a competitor.

Frequently Asked Questions

What is a normal respiratory rate for dogs at rest?

A normal resting or sleeping breathing rate for dogs is between 15 and 30 breaths per minute. This range applies to healthy dogs, dogs with asymptomatic heart disease, and dogs with well-controlled heart failure. Rates consistently above 30 breaths per minute are considered abnormal, and individual dogs may have lower thresholds flagged by their veterinarian.

Why do vets recommend monitoring respiratory rate at home?

Respiratory rates should be monitored in pets with significant heart disease and a risk of developing congestive heart failure. Home monitoring can catch the earliest signs of fluid accumulation before the condition develops into an emergency that requires hospitalization and oxygen therapy.

Can a wearable device accurately measure a dog's breathing rate?

Yes, if the device uses an appropriate sensor. BCG-based wearables detect the mechanical forces of each breath as they travel through the body. A 2025 study in Veterinary Sciences compared a BCG wearable against electrocardiography in dogs under normal conditions and found that the BCG device provided reliable data and was efficient at detecting heart and breathing rates. Accelerometer-only devices cannot do this — they measure movement, not respiration.

What is the difference between a dog respiratory rate monitor and a GPS dog tracker?

A GPS tracker answers the question: where is my dog? It uses cellular or satellite positioning to report location and typically tracks activity as a secondary metric. A respiratory rate monitor answers a different question: how is my dog's physiology behaving right now? It requires a sensor capable of detecting breathing signals directly, not inferring rest from the absence of movement. Some devices, including BCG-based wearables with integrated 4G GPS, provide both functions in a single unit.

What is BCG and why does it matter for respiratory monitoring in dogs?

BCG stands for ballistocardiography. It measures the mechanical micro-movements the body generates with each heartbeat and breath. A BCG sensor positioned against a dog's body can extract heart rate, respiratory rate, and heart rate variability from those signals without skin contact, electrodes, or fur shaving. BCG is the standard for non-invasive vital sign monitoring in pet wearables. Heart rate, respiratory rate, and heart rate variability cannot be inferred from step counts or GPS movement — they require a sensor capable of detecting the body's physiological signals at rest and in motion.

Is continuous respiratory rate monitoring better than manual counting?

Manual counting, when done consistently, gives a reliable snapshot. But a dog's breathing rate varies throughout the night, across seasons, and as their health changes over months. Continuous monitoring builds a personal baseline for each individual dog. A long-term study involving 703 dogs monitored over an average of 189 days found that heart rate and respiratory rate both decreased in early life, stabilized, then increased slightly in older dogs — a trend pattern that is only visible through long-term continuous data. A single manual count cannot show a trend. A device worn daily for three months can.

Should a healthy dog wear a respiratory rate monitor?

According to the Georgia Veterinary Medical Association, wearable devices that have been part of a dog's care can serve as an extension of veterinary monitoring when the vet already has a baseline for that patient. The data supplements what the vet sees in the clinic rather than replacing it. For healthy dogs, the primary value is establishing a personal baseline before a health event occurs, so that deviations are visible against a known normal rather than an assumed one.

Which dogs benefit most from respiratory rate monitoring?

Dogs living with cardiac conditions, respiratory disease, diabetes, epilepsy, or post-surgical recovery all benefit from ongoing respiratory data. Senior dogs and stoic breeds are particularly good candidates — stoic dogs often conceal discomfort until a condition is advanced, and physiological monitoring can surface changes before any behavioral signs appear. Breeds with structural respiratory vulnerabilities, including bulldogs, pugs, and French bulldogs, are another group where baseline respiratory data has practical value.
