Charlie Hall plays the dog-hating landlord. In real life, he would later adopt one of Laughing Gravy's puppies.
"Laughing Gravy" was the actual name of the little dog. It made numerous appearances in Hal Roach productions.
This film, along with Drôles de bottes (1931), were simultaneously produced in Spanish language versions, and the two shorts were edited together into one continuous film Los calaveras (1931). Laurel and Hardy read their lines from cue cards on which Spanish was written phonetically. At the time of early talkies, dubbing was not yet perfected. The same was done for a French language version, Les carottiers (1932).
Laurel & Hardy liked the "animal in the boardinghouse" plot. They used it prior to this movie with a goat in Entre la chèvre et le chou (1929) and would repeat it with a gorilla in Prenez garde au lion (1932). Many of the gags in this movie, including the bathing scene, originated in "Entre la chèvre et le chou (1929)".
The title and the dog's name is a euphemism at the time for liquor. Prohibition was still in effect when this film was made in February of 1931.
