Download the app

“I can personally attest to the app’s addictiveness. Almost immediately, it became a part of the near-unconscious ritual of checking that begins every time I unlock my smartphone…to remind you, as you go about your connected existence, that you have a dog, somewhere, and that he’s alive, and that you love him.”

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!

  • 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.

  • 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.

  • 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!
