For those of you out there whipping your offspring into shape by utilizing the Step2Play middleman, and burning your own fair share of calories on the GameRunner, it's about time Rover joined the fray, eh? The Dog Walker treadmill helps prevent doggy obesity and apparently relieves the dog's stress, all while helping it to exert all that pent-up energy from being cramped up in the house all day. Aside from sporting a smaller, dog-friendly design, casters to enable easy transport, and two side shields to prevent minor tumbling disasters, the machine also sports a safety leash which prevents the pup from sliding off the rear (or giving up on the goal) and a devilish remote control to vary the speed from 0 to 5-kilometers per hour (3.1 mph). So if you're tired of Fido's stomach dragging the ground while crawling around in misery, you can pick up its very own treadmill (to go along with that recently-purchased pedometer) for ¥15,800 ($131).[Via TokyoMango]
