The 'Whistle' activity monitor works to transform your dog's activity into quantifiable data. The device attaches to your dog's collar in order to track its every activity. Whistle then transmits that data about how much your dog is active and inactive to your phone.

A smartphone app allows you to see your dog's activity levels and track their health. At the end of each day, the app provides an activity summary. The report provides insights into your dog's actions along with warnings if something is amiss. If the Whistle senses that your dog is getting less rest than average, the app will notify you and provide hard stats.

Whistle also gives you the ability to predict health and look at trends. In addition, the app has access to the data of similar dogs so that you have a benchmark to compare your dog's stats to.
