Earliest Citation:
In rare cases, the raider, who has been interested only in making a profit all along, will take over the company. That's usually a case of the dog that caught the car. What does he do now?
—Alan Gersten, "Greenmailer Eying HNG/InterNorth?," Omaha World-Herald, November 24, 1985
Notes:
This idiom is based on the strange habit that some dogs have of chasing cars that are passing by on a nearby road. What on earth would one of these crazed canines do if it actually caught a car? This idiom is also seen as the dog that caught the truck (1993) and the dog that caught the bus (1994).
