An animal handler in Hollywood, Eddie (Jonathan Silverman) may work with cats and dogs, but he doesn't want to own any; he holds to his "no pets allowed" policy even when his son, Billy (Moises Arias) brings home the loveable 185-pound Beethoven, a St. Bernard. He'll have to change his mind, however, when the animal lead of a big movie goes missing, and the studio chooses Beethoven as a replacement! The slobbering sweetheart of a dog soon wreaks plenty of havoc on set, but in the end, not even Eddie can deny that the drooling, demolition-friendly dog is one of a kind. This charming entry in the popular Beethoven series also stars Rhea Perlman, Eddie Griffin, Joey Fatone, and the "Dog Whisperer" himself, Cesar Millan.
