See how diet impacts your dog’s health

With our new food pantry feature, you can add all your pet’s everyday foods to see how diet changes affect their health and weight.


Yes, you’ll need an annual subscription so your device can connect to the service needed to collect your pet’s data.

It can last up to two months on a single charge. But we recommend charging once it hits 25%. Battery life is also affected by WiFi and network coverage, so keep that in mind if you have a shaky connection.

Your USB charger will bring your device back to a full charge in about 90 minutes.

Technically speaking, we use a three-axis accelerometer to estimate the total amount of energy your pet used each minute. Then we use that energy estimate to determine if your dog is resting, wandering around the house, or in full squirrel chase mode.

TLDR: We learn from your pet’s behavior over time and use that
data to understand their activity levels.

Short answer: sensors and a lot of measuring. Your device has sensors that take 150 measurements of your dog’s motion every second. We then use our behavior detection algorithms, courtesy of our partners at Pet Insight Project, to detect specific movements like scratching or licking.

We use a device called a three-axis accelerometer. It senses how much your pet is moving, up to 50 times per second. We use that data from tens of thousands of pets to create an algorithm that accurately calculates a distance estimate.

Your device will track your dog’s health and activity metrics accurately in any orientation, as long as it is attached to your dog’s collar and not another accessory like a harness or leash. Whistle’s algorithms account for 360 degree rotation around a dog’s neck to ensure every run, roll, and rub is captured!

In order to establish a baseline of your dog’s unique behavior and lifestyle, Whistle™ collects calibration data over the course of a 7 day period. Once a baseline is established, Whistle™ can then provide insights regarding any new changes in your dog’s behavior relative to the baseline.

    Does Not Stay On

    I absolutely love this device and the new lavender color. I upgraded my Whistle Health to this 2.0 version in the hopes that the device would stay on better than the original Velcro straps. However, it fell off and got lost within a month of having the device. I was extremely disappointed given that my parents spent $70+ on this for me as a birthday gift. I don’t see any solutions for better securing the Whistle Health in the website’s online store.
