A startup called Whistle has developed something special for your dog, and at least on paper, it sounds like a pretty great idea. The device, a small metal disc that can be attached to a standard collar, is akin to human activity trackers like FitBit and FuelBand, but can tell you a lot more about your dog than just how active he’s been recently.

In a recent interview,Whistle’s co-founder and CEO Ben Jacobs promised that “it’ll fit any dog except a tea-cup Chihuahua,” and also mentioned that the University of Pennsylvania’s Veterinary Clinical Investigations Center has already made plans to use Whistle in studies. “Vets are like pediatricians where the patient can’t speak,” he continued.
Jacobs formerly worked as a consultant for Bain Capital, and helped design PetSmart’s retail strategy. In that same interview, he cited research statistics showing 80 million dogs in the United States (there are only 72 million kids) as one of Whistle’s principle inspirations. He even maintains that a dog tracker is definitively more relevant than a human tracker, stating that “The human quantified self can be subsumed by the phone – but your dog is never going to have a smartphone.”
