The title was taken from a Chuck Jones short Prest-O Change-O, a Merrie Melodies released on March 25, 1939, and reissued as a Blue Ribbon in 1947 by Warner Bros. It stars Happy Rabbit, in his 2nd appearance, and that character appeared in 4 cartoons from 1938-40. The character has now evolved into Bugs Bunny, who has his own walk of fame, appeared in more films than other classic cartoon character, and is now the Warner Bros mascot. It also stars the Two Curious Puppies, who only made six appearances before being retired. This short is now in the public domain, thus freely distributed through unofficial releases and of course YouTube. The video has been restored for Looney Tunes Platinum Collection: Volume 2, Disc 2. However, despite the name, the 2 cartoons however are not similar in plot and storylines.

When the veterinarian captured Crocker (in Doidle's body), he said "to the neuter scooter," which would indicate that he intended to neuter Crocker/Doidle. But in "Dog's Day Afternoon", Doidle had already been neutered.
