The plot of this mid-fifties short is that Charlie Dog is a salesman, the only difference is that he’s trying to sell himself, which one might call novel, but it is a certainly something that won’t work by pestering Porky Pig, as easy as Porky is to pester. It does however make for a fairly rudimental and forgettable short, something not helped by the fact that Charlie isn’t all that interesting a character.
And rudimentary it is, running like clockwork, or rather a one-sided conversation piece between two characters. Charlie is a talkie character, one who completely overwhelms Porky, who is left in the background, or at least might as well be.
The other thing the overabundance of dialogue does is take over take anything else in the short; the main issue is that the dialogue is not altogether funny, especially after seeing the short after the dozen time (which admittedly, was unlikely to be a concern to its creators back when it was made). A lot of it is basically exposition, which Chuck would later prove to be just as easily done by good art direction and a few choice words.
Not a great short, not terrible, just not that memorable, even after repeated viewings.
