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.

- Bill Cosby'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 Brick Joke 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).
