I don’t want to awaken the ire of any committed pet owners but I would be lying if I said I didn’t cringe a little bit when I hear about extreme pet products and services like doggie treadmills, pet psychiatrists or pet fitness centers.Still, I came across FitBark on the floor at TechCrunch Disrupt and while it could, at first, seem “extreme” I found that after hearing the creators’ explanation, their device actually seems pretty reasonable.
