Playing fetch with your dog is fun to a point, but if your dog is a tireless ball retriever, check out the cool new GoDogGo Remote Fetch. This innovative device is an automatic tennis ball launcher and throwing machine for dogs that could easily replace you as their new best friend. Just load it up with tennis balls, adjust the distance from 15' to 30' and set the launch interval from 7 to 15 seconds. It launches balls automatically, can be operated via remote control or, best of all, if you train your dog to drop the ball back into the machine, they can play on their own continuously for hours while you relax. It's a great idea, but hopefully the dog doesn't learn to insert other items like your slippers, cell phone and the family cat! (via Michael Kiely)
