Biometric Dog Collars: Tracking Your Pup’s Health or Just a Bark?

Technology has revolutionized our lives in numerous ways, from smart home devices to activity trackers. And now, it seems that even our beloved furry friends are not exempt from the wearable revolution. Biometric dog collars claim to monitor your dog’s vitals and provide valuable health insights. But are these claims bark or bite?

The Rise of Canine Wearables

Just like their human counterparts, these biometric wearables for dogs aim to track cardiovascular and respiratory health. Several companies are jumping on the trend, promising breakthroughs in monitoring a dog’s well-being. Three products set to release this year all make similar claims, utilizing contactless sensors to monitor heart rate and, in some cases, respiratory rate. This data supposedly helps to infer a dog’s emotional state or detect potential heart conditions. While GPS and activity tracking in pet devices are already common, the addition of health monitoring is a relatively new development. However, experts remain cautious about these claims.

The Challenges of Canine Biometrics

Adapting existing biometric technology for dogs presents unique challenges. Devices like Fitbit and Apple Watch rely on skin contact to obtain accurate readings through ECG and PPG sensors. Shaving our furry friends just to strap on a doggy Fitbit is not a practical solution. This has been a roadblock for implementing similar technology in pets.

To overcome this challenge, companies have turned to contactless sensors such as radar and acoustic technology. However, translating radar signals into meaningful health metrics is complex, and acoustic signals require filtering out background noise. Despite these obstacles, several companies claim to have cracked the code.

French company Invoxia has developed a smart collar embedded with mini radar motion sensors. These sensors emit radio waves to detect subtle changes beneath the fur. By filtering out extraneous movements, they extract the heart and breathing rates. Invoxia is currently conducting a clinical validation study to support their claims.

Meanwhile, Taiwanese company Industrial Technology Research Institute (ITRI) uses doppler radar technology in their iPetWeaR collar. In a small experiment, they achieved 98 percent accuracy when comparing heart rate measurements from iPetWeaR to ECG readings. Additional testing with veterinarians is ongoing.

Japanese company Langless takes a different approach, using acoustic sensors in a harness called Inupathy. Their tiny microphone records the dog’s heart rate, which is then analyzed using HRV (heart rate variability) analysis to determine the emotional state. Inupathy has undergone extensive testing on hundreds of dogs and collaborates with universities and laboratories in Japan.

The Need for Validation

Despite these claims, skepticism remains. Dr. Firat Guder, a bioengineering expert, questions what breakthroughs these companies have achieved that were not possible in previous years. He emphasizes the importance of data and validation to convince experts and the public.

Other veterinary professionals share this skepticism. Dr. Ernie Ward highlights the need for robust validation, emphasizing that the tech might be sound, but results matter. With potentially serious consequences, accurate and demonstrable health monitoring is essential.

The Future of Pet Tech

While the allure of monitoring our pets’ health is undeniable, the question arises: are these biometric readings actually valuable to the average pet owner? Veterinary experts suggest that weight monitoring might be more impactful, as weight changes can be acted upon. It’s important for pet owners to hand over the collected data to trained professionals who can interpret and act on it appropriately.

As the pet tech market continues to evolve, companies like Fi and Wagz are cautiously exploring new advancements. Integrating reliable technologies that penetrate fur for accurate measurements is a priority in future developments.

In the end, the promise of biometric dog collars and their potential to enhance our understanding of our furry companions is an exciting concept. However, until comprehensive validation studies are conducted and the true value of these wearables is demonstrated, it might be wise to approach them with a mix of curiosity and skepticism.
