Now that humans have all manner of fitness bands to help us get in shape, it only makes sense that dogs get one too. Whistle has launched its activity monitor collar attachment for dogs on Android. The $129 accessory loops around your dog’s collar and syncs up over Wi-Fi or Bluetooth with the accompanying iOS or Android app. You can set daily goals for your dog’s exercise and receive notifications when it meets them. Alongside the Android launch, Whistle has added several new features to the iOS version. The accessory is now able to break down activity into different categories, such as walking, playing and resting. Running and swimming are planned down the road. You can also now take advantage of Facebook and Twitter sharing if you want to show off how healthy your pet is.
