Do you remember Audi’s early ’70s “pack of dogs” promo? If I recall, you could get a free brand-new Audi Fox if you had a pack of same-breed dogs that could beat the Audi in a race. If I’m remembering this right, after an early loss to a pack of greyhounds, Audi altered the rules so it was a five-mile race, pretty much guaranteeing no dogs would have the stamina to win. Also, I think a few of the dealer-provided Audi drivers swerved menacingly at the dogs, and flung long chains of sausages out the windows, as Audi had no intention of giving away any cars.
Many dog owners were accused of doping as well, including one recorded incident with a Pomeranian that hit 45 mph.
Also, I may be making all this up.
