Step 1: About Whistle FIT


Pet Insight Project is powered by Whistle FIT

Available exclusively to Pet Insight Project participants, Whistle FIT offers pet owners and researchers a window into the daily lives of pets, anywhere they go. Whistle FIT tracks your dog's activity in a simple mobile application so you can ensure your best friend gets the regular exercise needed to stay happy and healthy.
