The Adventures of Rex the Wonder Dog #43

On a train trip cross-country, Danny tries to get the attention of movie starlet Jean Adair, while Rex drools over Fifi, her dog. Rex knocks down train robbers, stops a runaway horse, saves Danny from getting run over, but nothing impresses the snooty Fifi. Until at the very end, Danny carries Jean over a puddle, and Rex helps Fifi. Then they're heroes!
