Whirring, remote-controlled vehicles either terrify your dog or send it into a playful, sanguinary rage against the device (mine falls into the former). Sure, it's fun to grab a controller, sit back, and cause four-legged mayhem. But sharp metal and silicon plates in an excited dog's mouth is a recipe for busted gear and hefty vet bills.
If your dog is a furious appreciator of mechanical objects, and you have the liquid income to spare, get a GoGoDogPal remote-controlled dog toy. The device is a high-speed armored shell that comes in cat, groundhog, or racoon. This is blatant people marketing, as dogs could care less what's painted on the shell -- their desire is to disassemble the toy and learn about its inner robotic workings. But at least the design will give curious onlookers a laugh.
