Whistle, The Dog Tracker

The Whistle Activity Monitor For Dogs is a bluetooth collar that pairs with your phone, allowing you to track your dog’s food intake and exercise habits. If you’ve been struggling to micro-manage your dog’s carefree, happy life of treats and running around the yard to sniff things, this is the e-dingle for you. Plug your dog’s stats into the app and hitch them to your hell-existence of daily data entry.

At least it’s not as expensive as the Tractive GPS Pet Tracker, whose apparent use is to enable you to let your dog wander around freely all day, coming back only at night for device syncing and data transfer.
