The Adventures of Rex the Wonder Dog #43

In "The Doom Express!", Rex the Wonder Dog and his young owner Danny take a cross-country train ride that turns chaotic when train robbers strike and a runaway horse threatens the tracks. While Danny tries to impress movie starlet Jean Adair, Rex focuses on winning over her aloof dog, Fifi—earning his stripes by thwarting danger at every turn. Just when it seems like no heroic deed will win Fifi’s approval, a final act of kindness seals the deal.

In "Stop That Litterbug!", Rex the Wonder Dog teams up with a surprisingly sharp-eyed young man named Bobo during Oscaloosa Clean-Up Week, when a stray letter of credit blows into Bobo’s bag—unintentionally leading the town’s crooks straight into the Sheriff’s hands. With quick thinking and a little help from Rex’s keen instincts, Bobo’s litter-picking spree turns into a surprising act of heroism.

In "The Smallest Dog on Earth!", Rex the Wonder Dog teams up with scientist John Rayburn in a race against time when a mischievous squirrel accidentally shrinks Rayburn to bug-size with a failed formula. With the lab now a treacherous landscape, Rex must navigate towering obstacles and hungry predators to find a cure—proving that even the smallest hero can make a giant difference.
