Why health monitoring matters, according to a vet

Dogs are experts at hiding discomfort, so it’s rarely obvious when something is wrong. Noticing the subtle shifts — in activity, sleep, or mood — helps you catch issues earlier and have a more informed conversation with your vet.

Looking for answers? You've come to the right place.

Dogs can't tell you in words when something's wrong. Left unnoticed, small changes in activity, sleep, or mood can build into bigger problems. Regular monitoring helps you catch these shifts early, so you can act before they become serious.

Your dog's collar tracks activity, sleep, heart rate, and respiratory rate using onboard sensors. It also listens for vocalizations and reads emotional state — 24 distinct states across 7 core emotional families. The more consistently your dog wears the collar, the better Voicari understands what's normal for them specifically.

Activity is measured using motion sensors in the collar, which track movement throughout the day. This data is turned into daily stats like active time and steps, so you can see how your dog's activity compares day to day.

The collar's onboard sensors read resting heart rate and respiratory rate directly from your dog, without any extra hardware. Over time, this builds a picture of what's typical for your dog, so deviations are easier to spot.

Voicari listens to your dog's vocalizations and identifies their emotional state — from playful to anxious to distressed. Emotional patterns can be an early, easy-to-miss signal alongside physical vitals, which is why we treat mood as part of the overall health picture, not a separate feature.

No. Voicari monitors behavior, vitals, and vocal patterns, and flags changes worth your attention. It is not a diagnostic tool, and any concerns should be discussed with a veterinarian.

If you notice a sustained change you can't explain — in sleep, activity, vitals, or mood — it's worth mentioning to your vet, especially alongside any other symptoms. Think of Voicari's alerts as an early-warning system, not a replacement for professional care.

A summary of your dog's activity, sleep, and vitals over the past week, with an AI-generated overview highlighting anything notable. It's designed to give you a quick, digestible view of how your dog has been doing.

Voicari's model is trained on a large, breed-diverse dataset — over 1.16 million data points from more than 1,228 dogs across 110+ breeds — developed in collaboration with behavioral-labeling partners and an advisory board of veterinarians and canine-behavior experts.

Yes. Bark filtering happens directly on the collar — only bark events leave the device, while ambient sound and human speech are discarded on-device before anything is sent anywhere. Voicari is GDPR-compliant.

Voicari is currently open for Early Access pre-order, with the first devices shipping September 2026.
