Uh oh, Fido's gotten into the whipped cream! Or the shaving cream, or the soap suds, or the toothpaste -- the point is, white foam is dripping from his mouth. Cue people running away and screaming, "Mad dog! Mad dog!"

Sometimes it's a human being rather than a dog inspiring the panic.

In a [[MillionToOneChance million to one scenario]], a rabid French dog has made it through the Channel Tunnel!" The dog is shortly followed by its owner who explains that far from being rabid, it ate some soap, which it had mistaken for cheese because [[DirtyForeigner we do not have soap in France]].
* There was a depressing ''ComicStrip/BetweenTheLines'' strip where a dog had just finished eating some honey offered to him by a cat. The owners then think he's rabid, and the last panel shows the dog's tombstone as the cat smirks smugly.

* In one episode of ''Series/MysteryScienceTheater3000'', Tom and Crow find Mike passed out with foam around his mouth and begin treating him for rabies (the movie they'd been watching had to this point entirely been about the main character seeming to contract rabies). It turns out Mike simply fell asleep while eating a creampuff.


[[folder: Stand-up Comedy ]]

* Creator/BillCosby's stand-up routine "Roland and the Rollercoaster" deals with his crazy friend Roland, who used to do things like keep soap chips in his mouth. When people think Roland's head has been turned around by the roller coaster (due to Roland wearing his clothes backwards), there is a throwaway line from someone seeing Roland: "And he's got the rabies!" It's a good BrickJoke as it usually takes the audience a few moments to remember the soap chips in the mouth (which was mentioned early on in a fairly long story).
