The Automatic Canine Fetch Machine.

This award-winning toy keeps an energetic dog chasing tennis balls long after his human playmate tires, or even lets him play fetch all by himself (Play Video). The machine can be set to launch balls automatically or when a button on the remote control is pressed. You can adjust the distance (15' to 30') and interval (seven to 15 seconds) in which balls are launched, and if a dog is trained to drop a tennis ball into the machine, he can play indefinitely on his own. The machine's rugged plastic hopper has a 17-ball capacity and handles for easy transport. Includes six tennis balls and training tips. The launcher plugs into AC or runs on six D batteries (not included) that provide five hours of operation. 17 1/2" H x 15" W x 13 1/4" D. (11 lbs.)
