This month's edition of RoyalAuto (Royal Automobile Club of Victoria's magazine) referred back to this piece in their 'The Radiator' magazine of 1936.
"There has been some controversy whether owners of large dogs are humane when they subject them to risks by carrying them on running boards. If the dogs are tethered, they may be thrown off by a sudden swerve and strangled. If they are untethered, they may be dashed on to the roadway, thus suffering injury or constituting a danger to other drivers.
"The illustration herewith from Popular Mechanics (Chicago) shows a simple device. A sack made of canvas is clamped to the running board. A hole is made large enough for the dog's head to protrude. The hooks should be covered with a rubber to prevent damage to the enamel."
"Bird-dog's Palace" - Ha!
This fella thinks the step-plate is a doggy seat!
At the end of the journey
some exercise on the treadmill!
Or a quiet game of chess!
