This is the fifth short featuring Ralph Wolf and Sam Sheepdog.
Unlike his lookalike relative, Ralph wolf speaks. He also drives a souped up roadster, perhaps a nod to Wile E. Coyote's endless chases after the roadrunner.
Ralph the Wolf looks suspiciously like Wile E. Coyote.
Sam the Sheepdog's multiple appearances are reminiscent of another canine cartoon hero, Droopy.
Sam Sheepdog is seen using old fashioned arm signals to indicate what his car will do. These were common in the days before indicator lights, gps and safety sensors, and were required knowledge in most state DMV driving tests.
