Car Exercises Dogs (Sep, 1955)

A proposal for a car system to exercise dogs, digged out in a 1955 issue of Popular Mechanics:

"With six racing dogs to keep in top shape, Dewey Blanton of Columbus, Ohio, has developed a “canine exerciser” that fastens to his station wagon. Blanton built a frame to support a long plank beside the vehicle. Springs fastened to the plank are attached to the dogs’ collars, permitting the dogs to run wide. Longer chains keep the dogs in check. The broad plank bumper prevents injury to the dogs as they race along at 35 miles per hour. Best of all, the dogs seem to love the exerciser."

Dog-powered scooter

A fantastic way to harness the energy of your Great Dane, irritate those who might share the bike paths of the city with you and entertain the crowd. Inventor Mark Schuette of Oregon claims you'll be in total control of the speed and direction of the dog powered scooter because the dog is harnessed inside of the frame and subject to its steering and braking force.
