Mickey Mouse enters Pluto in a ritzy dog show. While Mickey grooms Pluto, Pluto starts swooning over Fifi the Peke. Things don't look good for Mickey and Pluto after the judge who looks over Pluto throws them out when the dog attacks the judge. But when a fire breaks out in the building (caused by a photographer), Pluto bravely goes in to save Fifi and is a hero.
- This cartoon is notable in that it was the last appearance of Mickey's older character design.
- There was later a comic strip based on it by Floyd Gottfredson although the comic strip was portrayed quite differently than the cartoon.
- This is Mickey's 100th appearance in a Disney cartoon.
- The original opening titles to the cartoon appears on the Walt Disney Cartoon Classics: Starring Pluto & Fifi VHS.
- This is the first appearance of Pluto wearing a green collar instead of red.(The poster still shows that Pluto's collar is red.)
