Meet Whistle

Whistle is the perfect companion for your daily adventures with your dog. The device and connected app keep you close to your best friend by helping you create healthy habits, track progress, and stay in touch when you have to be apart.

Play. Rest. Repeat.

Attach the lightweight device to your dog’s existing collar to track your dog’s daily activity and long-term health trends through a mobile app on your phone. When you open the Whistle app, you can quickly see how your dog is doing - and if they could use another round of fetch before dinner.

What people are saying

  • Every dog should have one!

    The Whistle has been an amazing addition to our family. I think what we have been most impressed with is how durable the device is. Ripley has put it to its test with playing with other dogs, swimming (even in frozen water!) and plenty of hikes and the Whistle won’t give in. Every dog should have one!

  • When we first read about Whistle, we immediately got on board.

    Whistle allows us to monitor Rory’s activity, whether playing, swimming, running or chasing the ball, and assures us he’s getting the exercise he craves. We also like that we can add other Whistle dogs and share in their adventures through comments, pictures, and encouragement to stay active.

  • Whistle is the perfect way for me to stay connected with Bella

    As a busy working 'dog-mom,' Whistle is the perfect way for me to stay connected with Bella on the go. I can easily see how she's doing throughout the day and am now so much more aware of her exercise and activity level!

  • With Whistle, I can check in on Kona and use the data to calm my internal overbearing parent.

    As an Oceanographer, I love data! Data is priceless and can provide answers I wasn't even looking for. Being able to establish a baseline for Kona allows me to monitor his trends over time and notice any anomalies.

  • Whistle gives me a window into the whole world of my dog

    Whistle gives me a window into the whole world of my dog. I can finally see just what he’s doing when I’m away, and identify times where he really needs an extra walk or play time when I get home from work. Tucker’s Whistle helps him tell me just what he needs.
