The 1936 dog sack was an innovative, though controversial, approach to traveling with pets. It offered a solution to keeping cars clean from pet hair and accidents by placing the dog in a canvas sack attached outside the car. While providing air and a view for the pet, the concept raised significant safety and animal welfare concerns and did not gain widespread acceptance.
