Whistle is this neat little device that tracks your dog’s activity levels, using an accelerometer to determine whether a dog is resting, playing, or sleeping. That data is synced using Wi-Fi or Bluetooth to an owner’s phone.
“We would love to be able to help these dogs live longer lives,” said Whistle co-founder and CEO Ben Jacobs, according to CNN. “The No. 1 indicator of a dog’s health is its own activity compared to its base line.”
