GPS collar for dogs • Biotracker

A dog GPS collar is now much more than a simple accessory. Whether to prevent escapes, secure walks, or keep an eye on your pet when they're not at home, the dog GPS tracker has become a daily ally for many owners. Unlike traditional collars, a connected dog tracker lets you locate your pet directly from a mobile app, with no distance limit.

In the event of an escape, an unexpected outing, or being cared for by someone else, it provides essential peace of mind, especially for curious, active dogs or those prone to wandering off.

But not all dog GPS trackers are equal. Accuracy, update frequency, and tracking reliability are key criteria for ensuring effective location, especially in an emergency. With its Max GPS subscription, the Biotracker fully meets these needs.

When it comes to safety, the difference between a real-time dog GPS tracker and a tracker with infrequent updates is significant. Some devices only refresh the dog's position every few minutes, which may be enough for occasional tracking, but quickly shows its limits in the event of an escape.

A dog GPS collar with Live Tracking lets you follow your pet's movements almost instantly. With the Invoxia Biotracker 2026 Edition, the position is updated every second, providing a precise and continuous view of movements, directly from the app.

This high frequency makes it possible to:

• react faster in the event of an escape,
• track a moving dog in real time,
• improve route and location accuracy, even in urban environments.

The dog tracker then becomes a true safety tool, not just a position indicator.

A real-time dog GPS tracker works on a simple principle: it uses cellular networks to transmit the animal's location to servers, then to the owner's mobile app. Unlike short-range trackers, this system provides extended coverage, with no distance limit.

The dog GPS subscription generally includes:

• access to the communication network,
• transmission of location data,
• access to the app and associated features,
• updates and continuous service improvements.

With the new Invoxia Biotracker subscriptions, users can choose a plan suited to their needs, combining real-time GPS tracking with advanced dog activity and health monitoring features.

Many owners look for a dog GPS without a subscription to avoid a cost that keeps adding up, month after month, on top of the collar itself. With the Biotracker, the free mode is not a demo version: over Bluetooth, when your dog is within range of your phone, you keep the heart and respiratory rate measurements, the activity and sleep tracking and the deferred GPS positions. That is a fundamental difference from most dog GPS collars on the market, where the subscription is mandatory from the very first use and only location is on offer.

There are dog GPS solutions without a subscription, often based on local technologies such as Bluetooth. These devices meet specific needs and can be a first step into connected tracking, especially for owners who want access to certain features without a commitment.

In the case of the Invoxia Biotracker, the no-subscription version lets you benefit from:

• dog activity and health tracking at a lower cost,
• use without network constraints, with Bluetooth operation ensuring compatibility anywhere in the world,
• simplified access to essential data via the app.

In return, location tracking relies on a limited range and the movement history is intentionally restricted. This setup is suitable for local use or occasional monitoring, but shows its limits when it comes to tracking a moving dog or reacting quickly in the event of an escape.

The maths are worth doing over the whole life of the collar: with competing trackers, the subscription renews every year and its three-year total often exceeds the purchase price of the device, without ever giving access to heart and respiratory measurements. With the Biotracker, you only activate a plan if you want real-time remote location: health tracking keeps working either way.

For owners who want a real-time dog GPS, with continuous location, greater accuracy, and a complete trip history, a subscription remains the most suitable solution.

The Invoxia Biotracker stands out from all other dog GPS trackers on the market thanks to its health- and well-being-focused approach. Beyond location, it includes a true heart monitor for dogs and a respiratory sensor for continuous biometric monitoring.

Thanks to the exclusive Heartprint™ technology, the Biotracker creates a unique cardiac signature for each dog, a visual imprint of heartbeats that makes it possible to detect unusual changes in rate and rhythm. The Biotracker is the only dog tracker in the world that can detect early signs of atrial fibrillation (Afib), even at an asymptomatic stage.

The Biotracker dog health monitoring includes:

• continuous measurement of the dog's resting heart rate and on-demand readings,
• monitoring of respiratory rate at night and during the day,
• tracking of heart rate variability (HRV), a key indicator of stress and recovery,
• analysis of physical activity and daily behaviors,
• generation of a personalized AI daily report for each animal.

These data do not replace veterinary advice, they complement it. The Biotracker allows owners to arrive at consultations with an objective history spanning several weeks, making diagnosis, treatment follow-up, and early detection of relapses easier.

Heart disease is one of the leading causes of death in adult and senior dogs. It often develops silently over several months before the first symptoms alert the owner. Continuous at-home dog heart monitoring changes the situation dramatically.

What is a normal heart rate for a dog?

A normal heart rate for a dog varies depending on size and age. The median resting values are as follows:

• Adult dogs (> 20 kg): median 59.5 bpm at rest
• Adult dogs (≤ 20 kg): median 62.1 bpm at rest
• Small dogs (≤ 10 kg): median 65.0 bpm at rest
• Senior dogs (≥ 10 years): median 68.7 bpm at rest
• Puppies (≤ 12 months): median 78.5 bpm, a higher value that is normal at this age

These values are population medians. What matters above all is each dog's individual baseline. The Biotracker builds it week after week, and only alerts you when your dog moves away from their own normal, not from a generic standard.

Data from the AI-collar study, conducted on more than 700 dogs by Prof. Valérie Chetboul, veterinary cardiologist.

Heart rate variability in dogs

Heart rate variability in dogs (HRV) measures the small time variations between each heartbeat. A gradual decrease in HRV can signal chronic stress, accumulated fatigue, pain, or the early stages of heart disease, well before the first visible symptoms.

The Biotracker measures HRV and tracks its changes over time, an indicator that most veterinary devices only capture during occasional consultations.

Atrial fibrillation in dogs: early detection

Atrial fibrillation in dogs is one of the most common arrhythmias, especially in large breeds (Labrador, Golden Retriever, Great Dane) and dogs with pre-existing heart disease. Its early signs are often subtle:

• slight exercise intolerance,
• unusual shortness of breath after moderate activity,
• temporary episodes of lethargy,
• irregular heart rhythm.

The Biotracker is the first and only dog tracker in the world to detect early signs of atrial fibrillation outside the veterinary clinic, thanks to Heartprint™ technology. It alerts you directly in the app. The earlier it is identified, the more effective the treatment options.

Mitral valve disease and respiratory rate monitoring

Mitral valve disease in dogs (MVD) accounts for more than 75% of acquired canine heart diseases. It particularly affects small breeds (Cavalier King Charles, Chihuahua, Bichon, Poodle) and progresses over several years.

Monitoring a dog's resting respiratory rate is the most reliable indicator for assessing MVD progression and treatment effectiveness. A rate above 30 breaths per minute in a sleeping dog is a warning sign.

The Biotracker measures this rate automatically and alerts you as soon as an unusual threshold is crossed. For dogs on heart medication, this continuous monitoring also makes it possible to adjust dosages, especially diuretics, using objective data collected over several weeks.

At-home heart monitoring: the essential complement to the veterinary consultation

An ECG during a consultation lasts only a few minutes, in a context that is often stressful for the animal. At-home dog heart monitoring offers what the consultation cannot: a continuous view in the dog's natural environment, at rest and during sleep.

By sharing the heart history directly from the Invoxia app, the owner arrives at the consultation with data spanning several weeks, information that the veterinarian cannot obtain anywhere else, and which enables a more precise diagnosis and truly personalized medical follow-up.

The best GPS collar for dogs depends above all on your needs. For some owners, the priority will be preventing escapes. For others, it will be tracking accuracy during walks, or the ability to monitor their dog's health over time.

Criteria to consider include:

• the GPS position update frequency,
• the tracker’s accuracy and network coverage,
• the battery life of the connected collar,
• comfort and weight for the dog,
• dog health tracking features (cardiac, respiratory, activity).

A dog tracker combining real-time location and cardiorespiratory health monitoring meets a complete range of needs, supporting the dog both outdoors and at home, and becoming a true preventive medicine tool. That is exactly the case with the Invoxia Biotracker.

There are currently several categories of dog trackers on the market. To choose the right one, it helps to understand what each technology can do, and what it cannot.

Bluetooth trackers

Bluetooth trackers for dogs work over short range: they can locate an object or animal only when a compatible smartphone is nearby. Useful for finding a lost item at home, they quickly show their limits for a dog on a walk or in the event of an escape. The range is generally limited to a few dozen meters, and location depends entirely on the presence of other connected devices nearby. Without a cellular network, there is no remote location tracking.

These solutions may be suitable for very occasional use or a tight budget, but they are not truly dog GPS trackers.

Classic GPS trackers

Dog GPS trackers rely on cellular networks (3G, 4G, or LTE-M) to transmit the animal's location in real time, with no distance limit. This is a major advance for safety: in the event of an escape, the owner can follow their dog's movements from anywhere, receive zone alerts, and find their pet quickly.

However, these trackers share one common limitation: they focus only on where the dog is, not on how they are doing. Location, route history, zone alerts, but no data on the animal's health, stress level, heart rate, or sleep quality.

The Biotracker: all-in-one dog GPS tracker and health monitoring

The Invoxia Biotracker is the only solution that combines both dimensions in a single connected collar. In addition to real-time GPS tracking every second via LTE-M network, it includes a true health tracker for dogs: heart rate, respiratory rate, heart rate variability (HRV), sleep quality, behavioral analysis.

Knowing whether your dog is active enough, resting well, or showing unusual signs of fatigue is a question most owners ask themselves, without always having the tools to answer it. The Biotracker provides a concrete answer thanks to precise and automatic dog activity tracking, with no action required from the owner.

Activities automatically recognized

Thanks to an onboard neural network, the Biotracker identifies more than 10 different behaviors in real time:

• Walking, tracking distances covered and pace, to ensure the dog gets the exercise suited to their breed and age.
• Running and trotting, distinguishing gaits for a detailed analysis of actual physical effort.
• Rest and sleep, duration of rest periods, nighttime sleep quality, and recovery score.
• Meals, detection of feeding times to track eating habits over time.
• Restlessness, recognition of unusual restless behaviors, which may signal discomfort, stress, or pain.
• Transport, distinguishing car or transit travel so as not to distort real physical activity data.

What these data make it possible to detect

Beyond simple step counting, the Biotracker's dog activity tracking makes it possible to spot gradual changes that often precede a health issue. A dog that walks less, sleeps more than usual, or shows a drop in energy over several consecutive days is sending a signal, often invisible to the naked eye, but clearly visible in the data.

The Biotracker alerts you if your dog's activity level deviates significantly from their personalized baseline, built week after week to match their real habits.

Calories, distances, behaviors: a complete dashboard

Each day is summarized with:

• calories burned,
• distances covered,
• rest time and sleep quality,
• a comparison of daily activity level with their usual averages and those of other dogs of the same breed in the Biotracker community.

These data are available at a glance in the Invoxia app, and included in the narrative daily report, for easy reading, without technical jargon.

For dogs being monitored for a chronic illness or recovering after surgery, this activity tracking becomes a medical tool in its own right: it allows the veterinarian to follow changes in the animal's mobility between consultations, objectively and in their everyday environment.

Invoxia designed the Biotracker as the most complete dog GPS tracker on the market, built for daily and long-term use. Compact (37g), lightweight, and comfortable, it fits the vast majority of existing collars without changing your pet's habits. Its battery life of up to 15 days and IP67 resistance make it a reliable companion in all circumstances.

With the 2026 Edition, the Biotracker takes a new step forward thanks to Live Tracking every second via LTE-M network, while retaining what makes it unique: being the only dog GPS collar in the world to combine real-time location, continuous cardiorespiratory health monitoring, and onboard artificial intelligence, all validated by an international board of veterinarians and cardiologists.

With the Biotracker, Invoxia offers the only GPS collar for dogs combining real-time location tracking and continuous cardiorespiratory health monitoring, a unique solution for owners who truly want to understand their dog every day, and a valuable tool to support their veterinarian in medical follow-up.
