"Laughing Gravy" was the actual name of the little dog. It made numerous appearances in Hal Roach productions.
A deleted end sequence lasting around ten minutes, Stan receiving news of a vast inheritance and discussing with Ollie how and if he could share it, was rediscovered in 1985, and has subsequently been released on video and DVD; the shorter two-reel version ended with the landlord committing suicide.
Laurel & Hardy liked the "animal in the boardinghouse" plot. They used it prior to this movie with a goat in Angora Love and would repeat it with a gorilla in The Chimp. Many of the gags in this movie, including the bathing scene, originated in "Angora Love".
This film, along with Be Big!, were simultaneously produced in Spanish language versions, and the two shorts were edited together into one continuous film Los calaveras. 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.
